PSP nitroFormant is a flexible dual formant filter offering two separate filters with independent pitch control for each filter and the ability to morph between them. The module features master input and output gain, frequency and resonance controls, and PSP’s renowned softSAT saturation algorithm.The PSP nitroFormant takes full advantage of the module format. It not only offers master stereo control-voltage-style inputs and outputs, but independent CV inputs for Pitch A and B, Resonance, Frequency, and Morph controls.

Taking the super envelope follower from PSP stomps and display functionality from PSP N2O, this flexible module can be fed from two sources, Feed A and Feed B, with separate control voltage-style inputs for each. In addition to adjusting the threshold, you can set whether the filter operates when the signal is above, below, or around the threshold. You can adjust the envelope’s attack, and also turn the attack hold on, off, or set it to boost the attack. You can choose between three filter slopes: sharp, soft, and smooth. You can set the amount of link between the two feeds, as well as the output polarity. PSP nitroEnveloper also features master input and output level controls and independent CV outputs for each feed. Finally, the large LCD-style display can be set to show peak or RMS metering.

Featuring the ultraflexible LFO from the super LFO from PSP stomps, and display functionality from PSP N2O, PSP nitroLFO includes a whopping ten waveform types plus an additional derived waveform type that reinterprets the selected waveform type based on the module settings, adds the derivative to the output, and offers a dedicated makeup gain control for the derived waveform. PSP nitroLFO gives you two offset controls along with a smooth toggle for each, and master trigger level, smooth, and tilt/width controls. There’s also a polarity switch and master output range control to blend between the two offset signals. Being a module, you also get a plethora of control-voltage-style ins and outs. PSP nitroLFO offers a 1V/oct control input, S&H input, direct trigger input, and double outs.

The stereo PSP nitroPhaser lets you set the left and right frequencies independently. You can select up to 32 stages for the phasing effect, and the module offers master input and output gain, along with depth and resonance controls with selectable right inversion buttons. PSP nitroPhaser also includes PSP’s renowned softSAT saturation algorithm. Finally, this module includes all the control-voltage-style control you could want, with master stereo CV ins and outs, along with CV inputs for both frequency controls, depth, and resonance.

The PSP nitroLoFi module offers continuously adjustable sample rate emulation from 48 kHz down to 750 Hz, with buttons for anti-aliasing and smoothing. It also offers continuously adjustable bit-rate simulation from 24 bits down to 1 bit, including a button for nonlinear emulation. PSP nitroLoFi also includes eight preset buttons, with settings for DVD players, tape machines, and more, along with selectable emulations of dither/noise shaping. Rounding out the controls are master input and output gain knobs. PSP nitroLoFi doesn’t skimp on control-voltage-style control either; in addition to master stereo CV ins and outs, there are individual CV inputs for sample rate and bit-depth control.

PSP nitroBQF is the module adaption of the BIQUAD from the PSP N20, with its two parallel multimode filters. This unusual module features two filters with four filter shapes each: low-pass, high-pass, bandpass, and peak. The filters have independent controls for resonance and saturation. You can set the filters to have a gentle 12 dB slope, a more aggressive 24 dB slope, or a steep 36 dB slope. The module offers adjustable input and output gain, and the famed morph control to blend the processed sound with the source. PSP nitroBQF takes full advantage of its module form; not only does it include master stereo control-voltage-style inputs and outputs, but it offers CV inputs for the frequency, resonance, and morph controls.

This comb filter offers separate frequency and depth controls for the right and left channels, as well as the ability to link them or invert a specific channel. The module lets you choose between a feed-forward or feedback comb filter structure (with crazy amounts of resonance), and either linear, cubic, or no interpolation. It also features master input and output gain controls, as well as PSP’s renowned softSAT saturation. PSP nitroComb takes full advantage of its module form; not only does it include master stereo control-voltage-style inputs and outputs, but it offers independent CV inputs for the frequency and depth controls for each channel.

PSP nitroSVF gives you all the flexibility and control options you could want in a state-variable filter, and then some. It offers two filters (A and B) with five filter types, frequency, resonance, and saturation controls for each, along with a morph control to blend the two filters. There’s master input and output gain and a choice between a 12 dB and a 24 dB slope for the filters. PSP nitroSVF also includes PSP’s renowned softSAT saturation algorithm. Don’t forget, as a module, PSP nitroSVF includes a ton of control-voltage-style options, too. You have master stereo CV ins and outs, independent inputs for both frequency and resonance controls, and a CV input for the morph control.

PSP nitroPitch provides the expected controls for input and output gain, semitone adjustment of up to an octave lower or higher, and adjustment of up to a hundred cents lower or higher. But that’s the only thing expected of this module. You can tune each channel separately or link the tuning of the two channels. You can select four different pitch shift resolutions: low, standard, high, or very high. You can switch the overlap of pitches to standard, high, or very high. You can flip the phase of the pitch shifted signal. Finally, PSP nitroPitch includes all the CV-style control you’d hope for, with stereo ins and outs, and individual CV control of semitone, cents, Tune L, and Tune R controls.

This noise generator module features two independent, true-stereo outputs and offers three types of noise: white, pink, and brownian, along with three distributions: flat, triangle, and gaussian. The module includes an adjustable output level with a range set, and features incredibly smooth control throughout the entire spectrum, from brownian to white. PSP nitroNoise takes full advantage of its module form; not only does it include master stereo control voltage-style outputs, but it also offers CV inputs for the noise spectrum and level controls.

PSP nitroADSR is an advanced envelope generator module. Beside a typical set of envelope controls (extended with delay and hold), it can generate envelope curves both linearly or filtered, work in either loop or continuous mode, and more. PSP nitroADSR offers CV-style controls for most of its parameters.

PSP nitroFreqShifter is an analog-like frequency-shifter module. Unlike pitch shifters whose operating principle is to shift the input signal up or down by a musical interval, the frequency shifter shifts the signal up and down by a given amount of cycles per second (in other words: frequency). The result is highly input-signal dependent. This makes it effective as a fine-tuning processor for drums, or for producing subtle spatial effects for mono guitars, or even sci-fi effects on voices.
