Peaks - Dual Trigger to Signal Converter

Mutable Instruments

  • $ 19900

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 ヨ making it very useful for duophonic patches or for controlling/synthesizing the kick/snare rhythmic backbone of a patch.

Classic ADSR
Peaksメ 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メ 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 モhiddenヤ functions.

    ADSR enveloppe generator

  • Segment durations ranging from 0.2ms to 8s.
  • Quartic attack, exponential decay, exponential release.
  • Other fancy modes implemented in the code, waiting to be unlocked!

    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.

    Drum generator

  • 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.

    Inputs, controls and outputs

  • 4 parameter edition pots.
  • Channel 1 & 2 trigger inputs.
