Greg Surges’ USB-Octomod is an interesting new USB device which allows the generation of computer-controlled analog synthesizer control voltages, in the range of approximately +/- 5V.
Using a small open-source and cross-platform host application, you can control the 8 output channels of the Octomod through a simple OSC interface. The OSC interface lets you control the Octomod from a variety of software.
For example, Octofaders, above, is a Pure Data patch that lets you use an iPhone or iPad to wirelessly control modular synth gear.
The Octomod is available as a kit for $159 and assembled for $249.
I wonder if it'll work with Monotron. Of course it does cost more than Arduino.
Monotron has cv ins that are labeled … so you could solder direct to the board.
You could also use a midi-2-cv to do this. I have had some issue with USB latency in the past, midi seems to be a faster connection.
Hey, the USB-Octomod should work with any device that expects a bipolar control voltage in. I've also spent a lot of time minimizing USB latency, and there's really no noticeable lag.

Thanks Greg.
Looks like a really cool kit and would be cool to sync a Monotron or Modular Device direct to an iPad.
Thanks! George Macklin made a TouchOSC/PD patch to interface with the Octomod: http://granularmatter.blogspot.com/2010/10/modula…
Might be a nice way to do it.
