Peaks provides 4 different functions in a small 8-HP package. Their common point? They are all about generating an audio or CV signal in response to a trigger, and are all focused on rhythmic works.
Peaks is a dual-channel module – making it very useful for duophonic patches or for controlling/synthesizing the kick/snare rhythmic backbone of a patch.
Peaks’ first function is a no-frills ADSR envelope with segment times going from 0.2ms to 8s. Carefully tuned envelope shapes (quartic attack, exponential decay and release) provide a smooth but nervous response.
LFO and tap LFO
Peaks’ can work as a free-running, resettable LFO, or as a tempo synchronized LFO.
5 waveforms are available, each of them with a shape/morphing parameter: wavefolded sine, variable slope triangle, PWM square, stepped triangle and sampled/interpolated noise.
A unique feature of Peaks is its ability to lock onto irregular sequence of taps: the module can detect the periodicity of the incoming trigger pattern, and adjust the duration of the LFO cycles accordingly.
Peaks can synthesize bass-drum, snare-drum and hi-hat sounds using a digital model of the TR-808 circuits. An alternate drum generation mode synthesizes more aggressive FM-style drum sounds.
2-channel trigger to signal converter.
Three control modes:
twin: Channel 1&2 share the same parameters but can be triggered independently.
split: Channel 1 is edited by knobs 1&2, channel 2 edited by knobs 3&4, with a simplified 2-parameter control scheme.
expert: Channel 1&2 are completely independent.
Four functions: ADSR envelope generator, LFO, tap-LFO, and 808-style bd/sd/hh generator. Four additional “hidden” functions.

LFO / Tap LFO
0.03 Hz to 160 Hz.
5 basic waveforms: square, triangle, sine, stepped, random.
Waveform variations and morphing for each of these: PWM, slope, folding/harmonics, step size, interpolation.
Phase at reset control.
Tap LFO can lock onto irregular rhythms.
Channel 1: 808 kick model with extra parameters (tune, punch).
Channel 2: 808 snare model with extra parameters (tune, decay).
Channel 2: A specific combination of settings transform the snare into a modelled 808 hi-hat.
