Thought some of you might find this interesting.  I'm working on a sequencer project, using a Radio Shack 90 in 1 Project Kit for prototyping.

I'm not sure if the Arduino's DAC is good enough to use for CV output, but I'm going to try it (CV is Control Voltage, the system used by old analog synths).  Then again, sometimes, glitchy is good.

I'll post updates as I make more progress.

Sounds cool. I look forward to seeing more :)

Well as the arduino hasn't got a DAC then I suspect it isn't.
It has some software that will generate a PWM output and you can convert that into a DC signal with a filter. But there are issues with the filter design for such a taxing application as this.
See:- http://www.thebox.myzen.co.uk/Tutorial/PWM.html

Aah, thank you.  This is my first project, still finding my way around.  The CV converter was just an idea to try and make the device as useful as possible down the road, it's not a requirement.  My 777 will do the conversion if I need it to, anyway.
