Description

Videos above demonstrate the original Mutable Instruments version of the open source Peaks. The CCTV clone is functionally identical.

Immutable Peaks is a clone of Mutable Instruments’ best-selling open source multi function signal generator.

Immutable Peaks provides 4 different functions in a small 8-HP package: ADSR, LFO / Tap tempo LFO, and drum synth.
Their common point? They are all about generating an audio or CV signal in response to a trigger.

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.

FEATURES:

ADSR envelope generator

• Segment durations ranging from 0.2ms to 8s.
• Quartic attack, exponential decay, exponential release.

LFO and tap-tempo 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 synth

• 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.

+4 Hidden Modes!
Hold the FUNCTION button for one second (it starts blinking). Peaks now provides four alternative functions instead of envelope/LFO/tap LFO/drum generation. These functions are:

• Mini step-sequencer (4-step in twin mode, 2-step in split mode)
• Trigger delay/shaper
• Trigger stream randomiser
• Digital drum synth

SMD is all preassembled, leaving only the through-hole parts to assemble – pots, jacks, LEDs, and buttons. The firmware has been pre-flashed.

Estimated time to solder is about 1 hr, and a build guide is available to walk you through the process
