Tiptop Audio CP909

Analog TR-909 clap clone with noise-trashing character

4 HP Eurorack module

The CP909 is a one-to-one analog clone of the Roland TR-909 clap sound generator adapted for Eurorack modular use. It faithfully recreates the iconic 909 clap through a quasi-random logic-based noise generator, with independent accent control and the added TRASH knob for clock-mangling the noise source into degraded, trashy textures beyond the original machine. It delivers everything from crisp classic house claps to heavily distorted percussive noise bursts.

Features

  • One-to-one analog clone of Roland TR-909 clap circuit
  • TRASH knob controls speed of the quasi-random logic-based noise generator
  • Independent ACCENT level control per module (unlike the original 909 global accent)
  • ACCENT IN normalled to GATE IN when no external accent signal is connected
  • ACCENT input accepts gate, trigger, or CV signals
  • ACCENT knob acts as fine output gain control when no external accent signal is patched
  • Onboard trimmer to balance clap sound versus clap reverb sound
  • Trimmer set to TR-909 service manual spec from factory
  • Eurorack +/-12V power compatible (original 909 used +/-15V)
