- A SWISS-ARMY KNIFE FOR PERCUSSIVE PATCHES
- 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 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, and are all focused on rhythmic works.
- Four in one…
- 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.
- 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.
- Specifications
- Inputs: 100k impedance, threshold at 0.6V.
- 16-bit CV/audio generation with 48kHz sample rate.
- Output level: 0 to +8V for envelopes, 10Vpp for LFOs and drum signals.

Parts List Notes
- Parts List has JLCPCB part numbers
- SW1, SW2 - JLCPCB C620311 - Tactile Switch, 6mm, 14mm
- SW3, SW4 - JLCPCB C501573 - Illuminated switch (ordered along with PCB]
- LEDs have Green body when off, but light up in yellow when illuminated
- Can use 100K pots?
- The pots are used to set levels into the STM32 analog pins
- 5pcs Red Common Cathode 7 segment display - MAKE SURE TO CHOOSE COMMON CATHODE
- Get a STM32 Programmer here
- The STM32F103C8T6 is the 64kb version and thus too small but SOMETIMES they are 128kb
- STM32F013CBT8 (128kb version) on ebay... not that many to choose from :/
- Added cap ref des C3, C4, C7, C12
- LEDs go Kathode down
