> I would love to see this module happen! The monophonic nature of analog could be handled with a bank of switches to select scale relationships, along with 1 or 2 extra cv or switching inputs for more control. It doesn't need to be perfect or on par with the best arpeggiators out there, I'd be happy with just the 32 pre-defined patterns as suggested. Clock in, main CV in, chord cv in, gate out, cv out would make me very happy :) Maybe also a way to control the pattern via cv but really in use I don't think it's needed, flipping a switch is probably easier than playing a chord on a real keyboard :P

You know, such a module is fantastically simple to implement in software using, say, an Arduino board. Solder on some CV inputs for root pitch and clock speed, and a button and some LEDs for scale, some others for direction (up, down, pingpong), a switch for one-shot / loop, and some CV outputs for pitch and gate. Then probably a few dozen or so lines of C code, written over a few days, should be sufficient. If there's not enough interest for a proper commercial arpeggiator module, I could whip up an amateur one like that over a few days. (Alas, as to *which* few days), it would have to be after I've finished Stepper Acid and a few other projects, which are actually more complex than an arpeggiator anyway. I would have made the arpeggiator first if I had any use for it, but I simply do the arpeggiation in MIDI before converting to CV as it's more versatile that way.)

Anyway, let me know if anyone would be interested in, say, such source code and schematics.

All the best,
Zoë.
