Noise Reap's DIY sequencer is a nine step voltage sequencer with hold and reset functions. Patchable gate outputs.  Loops at 9 steps if no information is given to the RST or HLD inputs.  It's skiff friendly, and reverse polarity protected - at a crazy good price!


  • CLK – Clock input for a square wave LFO, dedicated clock, etc.
  • HLD – A positive voltage here will cause the clock input to be ignored, thereby holding on the current step
  • RST – A positive voltage here will return the sequencer to step one - note that the sequencer will not start running again until the RST voltage goes low again.
  • CV Out – Voltage output corresponding to knob position (±2V, noon position is 0V)
  • HLD@ – Same as HLD (Note: If a cable is patched from 5 to HLD@, the sequence will be five steps long and stop at step 5)
  • RST@ – Same as RST (Note: If a cable is patched from 5 to RST@, the sequence will be four steps long and loop)
  • Outputs 2-9 – Gate outputs.  Any given output will be high (+5 V) for as long as the corresponding step is active

Like Spinal Tap, it's one more!Review by HipsterSpeedball
This was my first successful sdiy. I was so excited. I cleared my entire day and got to building. I followed the build guide on the Noise Reap site. Detailed photos helped also. PCB is cleary labeled. With 9 knobs/LED's and 16 input/output jacks make sure to take your time. I layed the components in the PCB and installed the faceplate gently. Hand tightened everything in place and made sure the LED's were aligned and soldered everything.

With some patience and a quick breaks in between, I was done after a few hours and got to playing. I'm not going to get into what this module can do, but if you're not sure, just go for it! (Posted on 1/26/2017)
