Original Commercial Product

• Mutable Instruments Peaks page
  • 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.

• 8 HP
• 25mm depth
• +12V@60 mA, -12V@2mA

Parts List Notes

• Parts List has JLCPCB part numbers
• SW1, SW2 - JLCPCB C620311 - Tactile Switch, 6mm, 14mm
  • Ordered on Ebay
• 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 :/
