5 PSP 84 Operation Manual 5 Installation To install any PSP plug-in, run the installer and follow the installation instructions on the computer screen. Please make sure that you select the appropriate plug-ins folder for your host application. VST hosts VST applications (such as Cubase, Logic, Nuendo, and WaveLab) require VST plug-ins to be installed into special folder. In most cases a VST application accepts plug-ins installed in the Vstplugins subfolder under the main applications folder, for instance, C:\ProgramFiles\Emagic\Logic Audio Platinum 4.8\Vstplugins. Some hosts, such as Steinberg hosts, use a shared plug-ins folder. If you want to use the PSP plug-in in more than one VST application, manually copy the plug-in dll file, which has already been installed into the chosen folder, to the appropriate VST compatible host application folder. For example, Cubase VST hosts VST plug-ins in its Vstplugins folder. Cubase VST 5.0 can also host plug-ins in a shared folder called Shared VST Plug-ins Folder. This folder is usually located at C:\ProgramFiles\Steinberg\Vstplugins. In order to install any PSP plug-in in other VST compatible applications, you should refer to the particular application's operating manual. DirectX hosts All DirectX applications (such as Sonar, Cool Edit, Samplitiude, SoundForge) allow you to install plug-ins and documentation in which ever folder you like (e.g. C:\ProgramFiles\plugins\) until it is a valid folder. Be careful not to use an empty folder path to install our plug-ins. This may happen when the setup application can't find a default installation path. To uninstall PSP plug-ins, choose the automatic uninstall option and follow the instructions on your computer screen.

6 PSP 84 Operation Manual 6 Overview PSP 84 is a high-quality processor, capable of producing a wide variety of delay-based effects. Two independent delay lines operating with variable sample rate and a precise tape saturation algorithm with adjustable gain that allow for convincingly sounding simulation of tape delay, including all the exciting effects resulting from tape speed instability. The Filtration section, consisting of three 2nd order switchable resonant filter types, can be used to process input, feedback or wet signal. The adjustable slope of the filter ranges from gentle, which is useful for simulating high frequency absorption, typical for tape delay and wet signal equalization, to extremely steep with high cutoff frequency peak making all the wild wah-wah and resonance effects easily available. The Delay line sample rate and the filter cutoff can be modulated by any of the 5 LFO waveforms that are automatically synchronized to the sequencer tempo or envelope follower with adjustable sensitivity and attack/release. Moreover, the PSP 84 contains the functional reverb unit with simplified setting, carefully tuned to exactly reproduce the sound of classic spring and plate reverberators. Features High quality, unique signal processing algorithms, Up to 10 seconds of delay time per channel (depending on internal sampling frequency), Continuous control over the delay time, Cross-channel feedback and independent channel settings with channel link mode, Tape saturation simulation with adjustable gain based on the algorithm used in our mastering processors, Modulation section consisting of a LFO and an envelope follower, mixed in any proportions, used for filter cutoff and delay line sample rate modulation, 5 click-free LFO waveforms and variable LFO channel phase offset, LP, BP, HP filter with adjustable cutoff and resonance, Flexible filter routing capabilities, Vintage reverberation module for faithful simulation of spring and plate reverb characteristics, Parameter filtration for smooth and click-free operation, Support for sample rates of up to 192kHz, MIDI and VST automation of all parameters, Logic Control support, Pentium IV optimization, Over 60 presets for easy start.

7 PSP 84 Operation Manual 7 Applications The PSP 84 is primarily meant for applying to individual tracks within a mix and experimenting with drum and synth loops. The included presets reveal its huge potential in processing vocal, guitar and bass tracks. Though it can be successfully used for adding classic sounding delay, its capabilities go far beyond that. The PSP 84 independent channel settings and cross-channel feedback allow for creating animated delay effects that are more spatial and cut better through the mix than a simple statically-panned delay. Resonant filters and a modulation section that synchronizes to the host tempo, make it possible to create superb auto-wah-wah effects, warm smoky dub sweeps, evolving ambient textures as well as to easily shape the wet signal's spectral contents. The PSP 84 can create both pristine clean sounding echoes or degenerate the signal to great extent - all depending on your needs -, thanks to the variable internal sample rate allowing the pitch-twist effects, rich vocal doublers, flangers and unsurpassed detune effects to be achieved. Guitarists that are not satisfied with dry and cold sounding tracks recorded using direct-boxes will appreciate the saturation algorithm, great for adding mild overdrive and harmonic contents enrichment. Last but not least, the unique reverberation unit allows for adding space and warmth that most of the native digital reverbs lack.

8 PSP 84 Operation Manual 8 Internal architecture Delay lines (DLY L, DLY R and VCO) The core of the PSP 84 comprise of two parallel delay buffers (one for each channel), operating with variable sample rate ranging from 0,5x to 2x of the host sample rate. There are two factors that determine the actual (audible) delay time in the PSP 84: actual buffer length, internal sample rate, The actual buffer length is set by the up/down buttons of the corresponding delay section or by the invisible slider (please refer to the 'controls' section of this manual for further explanation). It can also be expressed in rhythmic units (instead of milliseconds) as part of one bar which allows for faster setting. The Internal sample rate can be adjusted manually (manual knob in the VCO section) or controlled by the modulating signal coming from the modulation block. The easiest and probably the best way to explain how these two factors affect the audible delay time is to highlight the analogy to a classic tape delay. A basic tape delay machine (picture 1) is constructed in very similar way to an ordinary tape deck and consists of two heads, one for recording and one for playback. The main difference is that the magnetic tape is looped, e.g. after the audio has been recorded on the tape by the recording head it will be played back after certain time (delay time). This time depends on how long it takes for the tape to cover the distance between recording and playback heads, which in turn depends on the distance itself and on the tape speed. These two factors are the exact analog equivalents of PSP 84 actual buffer length and internal sample rate: head distance ~ actual buffer length, tape speed ~ internal sample rate. The longer the actual buffer length (distance between heads) the longer resulting delay time. The greater internal sample rate (higher tape speed) the shorter resulting delay time. Picture 1: simple magnetic tape delay It might seem that there is no point in having two ways of setting the delay time. This is not true. Although both methods can be used to set the desired delay time (at least within a certain range), they also affect other processing properties and are not equivalent. Changing the actual buffer length in the PSP 84 is equivalent to moving the playback head to the new position. This is done immediately and the result is that the buffer playback pointer (playback head) jumps to another part of the audio that was recorded into the buffer. If you are familiar with audio editing programs, you can think of it as of moving the playback pointer to another position while the audio file is being played. Changing the internal sample rate (tape speed) is

9 PSP 84 Operation Manual 9 very different from that because the playback is continuous. The Playback position does not jump to another part of the recorded audio. Instead, the recorded audio starts to be played back faster or slower. This results in its pitch to be altered too. If you increase the internal sample rate, which corresponds to increasing the tape speed, sound is transposed up, and vice versa. After the whole buffer has been played back, the pitch stabilizes because the audio is being played back at the same speed as it was recorded. In the digital domain the maximum frequency that can be reproduced is limited to half of the sample rate (this is called the Nyquist frequency). That is why the side-effect of lowering the internal sample rate is that the delayed signal is band-limited. This can be used to achieve low-fi effects that are required for certain purposes. The significant drawback of operating in the digital domain, that a sound engineer must be aware of, is the aliasing phenomenon. It occurs when the original audio is being downsampled (what happens when the PSP 84 s internal sample rate is lower than the host sample rate). If the sound that is being down-sampled contains frequencies greater than the new Nyquist frequency (half the new sample rate), they become audible as unwanted artifacts. Unfortunately some of the digital processing programs that are doing sample-rate conversion somewhere in their signal path, do not care about the aliasing problem which becomes clearly audible. There is no way to avoid aliasing in real-time applications. The only way possible is to minimize its adverse effect by high frequencies attenuation so that it becomes much less audible. The PSP 84 implements a 4th order low-pass anti-alias filter prior to the sample-rate converters, that cures the aliasing problem to a great extent. However, it cuts some of the high frequencies too, which may be unwelcome in certain applications where a crystal-clean fullband delay is needed, such as hihat processing. That is why, when the PSP 84 s sample rate conversion module (VCO) is switched off (which implies no aliasing), the anti-alias filter is deactivated making full-band processing possible. Every unit making sample-rate conversions (with the exception of down-sampling with an integer ratio) has to implement some kind of interpolation algorithm. The simple techniques of decimation and linear interpolation that are found in many commercial products, introduce high harmonic distortion. The PSP 84 uses high quality multi-point interpolators both at the input and output stage of the delay buffer. These interpolators have been designed to introduce low distortion while keeping the CPU-usage at the reasonable level at the same time. The result is a pristine clean sound all across the allowed internal sample rate range. The hardware tape delay machines damp the recorded sound by a certain amount every one tape lap. This makes the sound to be quieter with each repetition. The PSP 84 contains a similar mechanism - feedback path. The feedback value defines the attenuation of the signal and ranges from -oo db to 0dB, which corresponds to one signal repetition and to lossless infinite signal recirculation, respectively. In addition, the PSP 84 has controls that let you set which part of the signal being fed back goes to the same channel and which to opposite. This allows for creation of interesting stereo delay effects. Filter (FLT) The PSP 84 is not only capable of attenuating the feedback signal. It can shape its spectral contents, making some frequencies to be attenuated more than others, thanks to the filter section. Three filter types are available: low-pass, band-pass, high-pass.

10 PSP 84 Operation Manual 10 All of them have been mathematically derived from analog 2nd order resonant filter prototypes and, though not 100% equivalent, manage to keep most of their character. For each filter type, cutoff frequency and resonance can be set. The resonance range let you shape the filter slope from very soft, useful for gentle equalization, to steep with high peak around the cutoff frequency, that makes the PSP 84 really scream. The Filter cutoff can be controlled by the modulation section as well. The modulation depth can be both negative and positive, letting the asymmetric LFO waveforms such as sawtooth to be inverted (up-saw becomes down-saw). When modulation depth is not equal to 0, the manual cutoff knob controls the center frequency around which the actual frequency oscillates. The Filter section is not only limited to changing the spectral contents of the feedback signal. There are three points within the PSP 84 s signal path, where the filter can be plugged: input (IN) - input signal before any other processing is filtered; filtration affects both dry and wet signals and the filtered signal is recorded to the delay buffers. This mode is the best for wah-wah effects and is identical to having wah-wah and delay connected in series, feedback (FB) - both feedback and wet signals are filtered; the result is that the first repetition is to be filtered and every next one is to be filtered more and more. This mode is useful for simulation of frequency absorption coming from wall reflection as well as for exciting resonant effects. wet (FX) - wet (processed) signal is filtered; this mode allows for degeneration-free signal recirculation within the feedback path and controlling the output signal spectrum only. WARNING! The loud feedback may damage your speakers and ears! When the filter is operating in FB mode the plug-in can easily become unstable. Always start with low feedback and resonance values while in this mode and increase them gradually to achieve the desired effect. It is a good practice to lower the plug-in output level too. Saturation (DRV) In order to make the tape delay simulation sound more convincing, the PSP 84 has an advanced tape saturation algorithm. The saturation module is located just before the delay buffer, so that the input signal, as well as the feedback signal, go through it. The only adjustable parameter of this section is gain. It allows for setting the desired amount of saturation - from mild harmonic contents enrichment to heavy overdrive and distortion. The saturation algorithm is based on PSPaudioware.com research and experience in programming the award-winning mastering processors, and its sound is warm and pleasant unlike most digital overdrives, at least for low gain values. The Saturation module is responsible for calculating the envelope follower signal too (explained in the modulation section description later). This signal has nothing to do with the saturation in fact, which may be a little confusing. The easy (and correct) way of thinking about it is that both the saturation gain, and the envelope follower sensitivity controls have been integrated into one knob. Turning up the DRV knob will increase not only the saturation amount, but also the envelope follower sensitivity (and even, if the saturation block is off, effectively allowing you to adjust it when you do not want to saturate the signal).

11 PSP 84 Operation Manual 11 Modulation (MOD) The Filter cutoff and internal sampling rate can both be controlled (at the same time) with the signal that is generated by modulation section. This section consists of two main elements: low frequency oscillator (LFO), envelope follower. The LFO is capable of generating the following waveforms: sinusoidal (SIN), pulse (SQR) with 50% pulse width, triangular (TRI), sawtooth (SAW), random (RND). The waveforms that have discontinuities (SQR, SAW and RND), are low-pass filtered to make the plug-in operation click-free. The random waveform is synced with the start of the bar, if the host is capable of providing the plug-in with the necessary information about the current song position. The LFO rate can vary within the range of 0.01 Hz to 15 Hz and can be adjusted freely or host tempo related. The LFO waveforms that are generated for the left/right channel do not have to be the same. In fact they can be phase-shifted which allows for very interesting fat chorusing and panning effects when modulating the internal sample rate. The RND waveforms behave in a different manner - if the phase offset is set to 0, the LFO signal is the same for left and right channel; if it is not 0 then the plug-in generates two (usually) different random numbers - one for each channel. The Filter cutoff is always modulated by the left channel LFO signal. The LFO signal can be mixed in any proportion with the envelope follower signal, making up the final modulation signal. The Envelope follower analyses the input signal. Its value depends on the weighted average of the absolute signal level, calculated for a certain time window. The width of the window is adjusted with the 'speed' knob. Note that the envelope follower sensitivity can be controlled by turning the DRV knob of the saturation block. Reverberation (RVB) Included with the PSP 84 comes the vintage reverb module, capable of simulation of spring and plate reverberator types. Many commercial reverb units available attempt to simulate virtual spaces through precise early reflection shaping and generation of a dense reverberation tail. Unfortunately they often prove to be of little use in the mix, even if sounding convincing when listened to in isolation. PSPaudioware.com made an attempt to meet the musicians and engineers demand for a classic mechanical reverberators simulation by analyzing their physical properties and implementing the reverb topologies that match those mechanical constructions close. The results produced by the two reverb types are significantly different. The Spring reverb creates a periodic tail, something that is usually considered unwanted by reverb programmers. However, this is close to the actual way the spring reverb acts and it turns out to sound surprisingly good in certain recording situations. The Plate reverb has a denser and brighter tail being not as periodic as Spring this is typical for physical plate reverberators. The reverb module can operate in two modes - processing only the wet signal or the output signal, consisting of dry and wet signals mixed in the proportion set by the 'mix' knob. It has an adjustable damping that effectively controls the reverberation time and the reverb amount, which in fact allows for setting the internal mix proportion.

12 PSP 84 Operation Manual 12 Main (MAIN) The input signal can be either attenuated or amplified before further processing, by setting the 'input' knob. Since the PSP 84 contains non-linear elements (saturation) and an envelope follower within its signal path, the input level does not only change the volume, but can also affect the sound itself (its spectrum). The dry and wet signal can be mixed in any proportions. The '-6dB method' has been used for mix control, which means that in center position, when the proportions of the dry and wet signal are both 50%, both signals are attenuated by -6dB. Though it may feel uncomfortable that most of time the result of mixing is too quiet when compared to the level of the dry or wet signal only, the point is that the PSP 84 is designed to deal with short delay times as well, and the '-6dB method' becomes more convenient in this situations, when the alternative 'equal power method' would cause clipping. The outgoing signal can be attenuated or amplified allowing for final level adjustments. The PSP 84 acts differently in bypass mode than most other plug-in processors do. Activating this mode does not stop processing, but only copies the plug-in input to its output. All the processing is still done in the background. Even though it eats up CPU resources, this seems to be the only appropriate method for processors that have feedback in their signal path.

14 PSP 84 Operation Manual 14 Controls The PSP 84 front panel consists of: display, input level meters, controls. The display is used to show continuous parameter's values (continuous parameters are described below). Input level meters (or headroom meters) indicate the peak level of the input signal. The Input signal level can be adjusted with the INPUT knob. Controls are used to change values of parameters. Parameters affect the way that the signal is processed and thereby the sound. Each control has a parameter bound to it. If you change the position of the control with your mouse (or MIDI control surface), the value of the parameter that is bound to this control changes too. The opposite is true as well - if the value of the parameter is changed by an automation event sent by the VST host, the position of the control will be adjusted to reflect this change. There are two types of controls used in the PSP 84: continuous controls - knobs and invisible sliders discreet controls - switches, buttons Continuous controls are bound to the parameters that can have any value from an allowed range, for example filter cutoff. Discreet controls are bound to the parameters for which only a few values are allowed, such as filter type. The PSP 84 front panel is divided into sections that correspond to the internal modules that process the incoming audio: DLY L - left channel delay line, DLY R - right channel delay line, FLT - resonant filter, DRV/ENV - saturation module and envelope follower sensitivity, MOD - modulation signal source, VCO - delay line sample rate control unit, RVB - reverberator, MAIN - levels and mixing. The FLT, DRV/ENV, MOD,VCO, RVB and MAIN sections can be switched off. We recommend doing this for the sections that are not needed for current application, to save CPU resources. The section is switched on/off by clicking on its name. The only exception is the MAIN section that is switched by clicking on the BYPASS button. DLY L and DLY R sections cannot be switched off and are always active (unless the plug-in is turned off totally by the host application). Clicking on the name of the DLY section makes the section the parent, while the opposite channel section becomes the child. The parent section has the following two meanings: its delay time is shown by the display, when LINK is activated, the parent section settings are copied to the child section. The LINK button allows the left and right channels to share the common settings. If link mode is active, whenever the control position (and the value of the parameter bound to this control) of one channel is changed, the opposite channel follows this change immediately.

15 PSP 84 Operation Manual 15 There is no parent/child section while in link mode. To indicate this both DLY L and DLY R sections are lit. Most of the time the display indicates the delay time of the parent section. However, when the position of the continuous control is changed, the current value of the parameter bound to this control is shown on the main display for two seconds. After that it switches back and shows the parent section delay time again. Since the values of the parameters bound to discreet controls can be easily read from the control's position, they are not shown by the display. The PSP 84 contains the following parameters, grouped in the sections: I. DLY (L/R) sections DLY L/DLY R - parent channel indicators/switches. The parent channel delay time (expressed in ms or in rhythmic value, depending on which mode is set), is displayed on the main display. MODE - switches the delay time setting mode; the delay time can be set in ms (TIME) using INVISIBLE SLIDERS and DOWN/UP buttons or in tempo-dependent rhythmic value (NOTE mode), expressed as the numerator and denominator, using DOWN/UP buttons. If the host application is capable of providing the plug-in with tempo information, the PSP 84 will get in-sync automatically when in NOTE mode and will follow every tempo change. If you use a host that does not have such functionality, you can still set the tempo manually by clicking on the main display area and dragging left/right or up/down. DOWN/UP: - when in TIME mode used for setting the delay time in miliseconds. Press shift or ctrl key to increase the step. Please note that the step depends on the delay time RANGE set. The minimum step is 1/1000 of the current range. - when in NOTE mode used for changing numerator/denominator values. The result is obtained by dividing the numerator by the denominator, defining the tempo-related delay time expressed as the fraction of one bar. Press shift or ctrl to decrease the value. INVISIBLE SLIDERS - two sliders (one for each channel) located between DOWN and UP buttons used for setting the delay time in ms. Simply click on them and drag your mouse while keeping the mouse button down. They do nothing when operating in NOTE mode.

16 PSP 84 Operation Manual 16 RANGE - changes the delay time range; the available ranges are: 100 ms, 1000 ms, 5000 ms. Setting the range to be narrower allows for finer delay time setting. The Range can only be set manually when the plug-in is in TIME mode. When in NOTE mode, the range is automatically set to be as narrow as possible with the actual delay time resulting from numerator and denominator settings and the current tempo. In NOTE mode, the resulting delay time may exceed the maximum allowed value of 5000 ms. If this happens the display starts to blink and the actual audible delay time is set to 5000 ms. FB - sets the feedback attenuation. This can be any value from -oo (no feedback) to 0dB (lossless signal recirculation) with -6dB in the center position. FB PAN - controls the feedback panning for the channel. The signal can be fed back to the same channel and to the opposite channel in the proportion that is controlled by this knob. DLY INV - inverts the wet (delayed) signal phase. FB INV - inverts the feedback signal phase. LINK - links the channels.

17 PSP 84 Operation Manual 17 II.FLT section FLT - activates/deactivates the filter section. MODE - controls where the filter is plugged in within the PSP 84 s signal path. There are three modes available: IN - input signal is filtered prior to any other processing, FB - both feedback and wet (effect) signals are filtered. This results in the first occurence of delayed signal to be affected and each consecutive repetition to be filtered more and more. FX - wet (effect) signal is filtered. In this mode the signal can recirculate in the feedback loop unaffected (without degradation) and only the wet signal, just before it is mixed with the dry signal, is filtered. TYPE - controls the filter type. Can be any of the following: LP - low pass resonant filter, BP - band pass resonant filter, HP - high pass resonant filter. CUTOFF - filter cutoff frequency. When the cutoff modulation is not equal to 0, then the value set using this knob is the center frequency around of which the actual cutoff frequency oscillates. The allowed range is from 50Hz to 16kHz, with 1kHz in the center position. RES - filter resonance. Sets the height of the peak at the cutoff frequency. In 0 position there is no resonance at all, in maximum position the filter is close to self-oscillation. Be careful when turning this knob up, particularly when the filter is in FB mode, since higher resonance values may result in instability. MOD - cutoff modulation. The Filter cutoff can be modulated within the range of octaves. This knob allows the modulation depth to be set. If turned counter-clockwise from the center position, then the modulating signal is phase-reversed, allowing for example to change up-saw waveform into down-saw.

18 PSP 84 Operation Manual 18 III. DRV/ENV section DRV - activates/deactivates the saturation section. DRIVE - has two bound parameters: saturation gain ranging from 0dB to +24dB with +12dB in center position. This affects the saturation depth. Please note that even if this knob is set to 0dB, there is some saturation unless the section is switched off. envelope follower sensitivity. This is active even if the section is switched off! IV. MOD section MOD - activates/deactivates modulation section. If it is switched off, neither filter nor vco is modulated, even if the modulation depth controls are set to the values other than zero. MODE - switches the LFO rate setting mode: FREQ mode - the LFO rate is set in Hz using the FREQ knob, NOTE mode - the LFO rate is expressed in tempo-related rhythmic value using DOWN/UP buttons for setting numerator and denominator. This is very similar to the NOTE mode of the delay sections. If the resulting LFO rate exceeds the allowed range of 0.01Hz - 15Hz, the display starts to blink. DOWN/UP: in FREQ mode - these buttons changes the LFO waveform, in NOTE mode - they set the numerator and denominator values (press shift or ctrl to decrease the value).

19 PSP 84 Operation Manual 19 WAVE - clicking on the corresponding symbol changes the LFO waveform. Clicking on the already active waveform symbol restarts the LFO. There are 5 LFO waveforms available: sinusoidal, pulse with 50% width (square), triangular, sawtooth, random (synced to the bar start if the VST host is capable of sending current song position information). When in FREQ mode, the LFO waveform can be set using the DOWN/UP buttons as well. FREQ - sets the LFO frequency when in FREQ mode. The range is 0.01Hz to 15Hz with 3Hz in the center position When in NOTE mode, this knob's position is automatically adjusted to show the actual LFO rate, resulting from numerator and denominator values and current tempo. PHASE - controls the phase offset between the LFO signal for the L/R channel within the range of -90 degrees to +90 degrees. Only the VCO can be modulated for each channel independently. The filter is common for both channels and is always modulated by the left channel modulation signal. SOURCE - sets the proportion of the LFO and ENVELOPE FOLLOWER signals, comprising the final modulation signal. SPEED - integrated control of the ENVELOPE FOLLOWER attack/release time. It changes the width of the time-window for which the average absolute input signal value is calculated. The allowed range is 100 ms to 1000 ms.

20 PSP 84 Operation Manual 20 V. VCO section VCO - activates/deactivates the section. If this is off, then the delay lines are operating with the same sample rate that the host does. Antialias filters are then deactivated too, allowing for full band-width processing. MANUAL - manual control of delay line sample rate within the range of 0.5x - 2x of the host sample rate. MOD - delay line sample rate modulation. If the LFO phase is not equal to 0, then each channel delay line is modulated separately by its own modulation signal. VI. RVB section RVB - activates/deactivates the reverberation section. MODE - lets you apply reverberation to the wet signal (FX) only or to the final output signal (OUT) (after the dry signal has added to the processed signal). TYPE - switches between two classic (mechanical) reverb types. SPRING simulates the spring reverb. In this case the reflections density does not increase with the time and reverberation pattern is periodic. PLATE recreates the plate reverberator characteristics that are brighter than a spring reverb and the reflections density increases with time.

21 PSP 84 Operation Manual 21 DAMP - controls the reflection damping, effectively determining the reverberation time. AMT - sets the internal proportion of the dry and wet signal. Please note, that this is internal to the reverb section so the dry signal here can mean either the PSP 84 wet signal (if the reverb mode is FX) or its output signal (if the reverb mode is OUT). VII. MAIN section MAIN - unlike all other section indicators, this one cannot be switched by clicking on it. It only shows whether the unit is in bypass mode or not. Use BYPASS switch to control this. INPUT - controls the input signal attenuation/amplification. MIX - sets the proportion of dry (unaffected) and wet (processed) signal in the output signal. OUTPUT - attenuates/amplifies the output signal.

22 PSP 84 Operation Manual 22 BYPASS - activates the bypass mode. When bypass is on, all the processing is still done in the background even though the PSP 84 s output signal is the same as its input signal. VIII. Other There is an additional INVISIBLE SLIDER located on the main display area used to set the BPM tempo manually if the host is not capable of providing the plug-in with tempo information Clicking on PSP 84 logo brings up the BACK PANEL showing the registered owner name and version information.

23 PSP 84 Operation Manual 23 Factory presets The PSP 84 has been equipped with a large number of factory presets that allow for an easy start and will show you some of the plug-in s exciting capabilities. Switching between presets is usually smooth and click-free. Unfortunately, some VST hosts do not have controls for navigating through the presets one by one by pressing up or down buttons, instead they only allow you to choose the presets from the drop-down list. In this case a short processing break may occur. The PSP 84 contains the following presets: 1 4 Feedback, 1 4 Feedback LP, 1 4 Feedback->C, 1 4 Single, 1 4 Single LP, Feedback->R, Feedback, X-talk, 1 8 Feedback, 1 8 Feedback BP, 1 8 Single, 3 16 Feedback, 3 16 Feedback HP, 3 16 Single, X-talk, Feedback, 1 12 Feedback, 1 4 Bounce, 1 8 Bounce, Synesthesia, Doubler Rough, Doubler Stereo, Doubler Verb, Mental Illness, Flanger Light, Spitsbergen, Splasher, Takeawalk, Satori, Gasherbrum Four, Seti, Hollow, Sarawak, South Pole, Deja Vu,

How to use presets? Using presets in Cubase, Nuendo or WaveLab To use our presets under Cubase, Cubasis or Nuendo, just click on the preset arrows to try the programs one by one. Alternatively, you can open the preset list to choose a preset from. To use presets under Wavelab, just click on the PRESETS box and select a preset from the list. Using presets in Logic To use presets under Logic just click on the PROG01 text box. The preset list will appear. Click on the name of the preset to load it. Using presets in other VST Refer to your host application's manual for details on using internal VST presets. There are still some VST applications (such as Paris or WaveBurner) which don't support internal VST presets. In that case we recommend users to share presets between users. Using presets in DX host There is no standard way of implementing the presets is Microsoft DirectShow (part of DirectX) specification. However, some companies made an attempt to enhance DirectShow to support presets. The PSP 84 implements the IStaticFilterPreset interface, introduced by Sonic Foundry, that has become a standard and is supported by most DX compatible host applications. However, since it is possible that your host does not support this interface, we advise you to refer to the host's manual or use the host manufacturer support service to check

25 PSP 84 Operation Manual 25 this. You will not be able to use the PSP 84 s predefined presets if your DX compatible host does not support the interface mentioned. Note that you will be able to save and load your own presets, though. The lack of the IStaticFilterPreset implementation does not affect any other PSP 84 functionality.

26 PSP 84 Operation Manual 26 External controllers and automation Every PSP 84 parameter can be automated, provided that your host application supports it. Many of the VST and DirectX compatible commercial sequencers and multitrackers available are capable of recording and sending automation information. However, some hosts contain limitations, such as a restricted number of automatable parameters per plug-in or low automation resolution, that can make automation difficult or impractical. If you encounter any problems with automating the PSP 84 parameters, always refer to your host application documentation for details. Besides VST and DirectX automation, the VST version of PSP 84 can be controlled via MIDI. This can be used for real-time control of the plug-in using any MIDI control surface that is capable of sending MIDI Control Change (CC) messages. Once the PSP 84 has been activated in your host application by plugging it anywhere in the audio path, the new MIDI port (usually named PSP 84 ) becomes accessible: The plug-in s engine and user interface respond to the messages that are sent to any MIDI channel of this port (it operates in OMNI mode). Furthermore, MIDI automation can be used to overcome problems, arising when the number of automatable parameters is limited by the host application. The PSP 84 has been designed, developed and tested to work properly with Logic Control from Emagic. Plug-in parameter values can be changed in real-time using LC faders and Vpots. The parameter names and their values appear on Logic Control s display, making navigation easy and convenient. The MIDI Control Change (CC) numbers assigned to PSP 84 parameters are fixed.
