Great tracking, low temperature related pitch drift, subsonic to supersonic frequency range, and a phat sawtooth core. In addition to the standard features there is a folded or “freaked” triangle out.

Inputs:

  • 1V/Oct
  • CV (Exponential) – Voltage at this input affects frequency, and is attenuated by the CV knob.  The CV knob ranges from fully off to fully open - when fully open, 1V = about three octaves.
  • RST (Hard Reset) - Add another oscillator output of similar frequency here to track them together, or use a wildly different frequency for new timbres and sideband frequencies.
  • PW – Changes the pulse width of the square wave.

Nice Oscillator, Build Guide MIAReview by charliehuge
This is a nice-sounding oscillator for the money, and assembly isn't too tricky. Through-hole components all the way through, easy to get the 2 PCBs connected, will probably take you a few hours to get it together. Solid build design, too.

On the down side, the build guide is MIA from the internet and Noise Reap's website makes (almost) no mention of ever producing such a kit. I was able to figure out what went where by the (very nice) markings on the PCBs, looking up some part numbers, and going through the parts list spreadsheet and schematic. At one point, I thought I had an extra resistor and couldn't for the life of me figure out where it would go on the board. Turned out it was the 2k tempco that goes underneath the CA3046.

If you're up for some adventure, this is a good kit. But I assume the build guide would have made the process significantly easier. (Posted on 10/2/2016)
