I'm looking to try this one now because a friend is interested in it...
Has anyone considered running it at 5v? That's really what most of those logic chips want. I don't see higher voltages being in any way necessary. Rather have a thing that works 100% instead of worrying about chips frying all the time. I have no interest in doing a total clone, as long are functions are similar and it sounds weird. :lol:

digit’s schematics are all missing now. Can anyone post schematics for his final version and the arpeggiator?

The schemo is in the DEFX build doc, here;

As for the arpeggiator, I used an EHX 8 Step for the CV steps. There is a DEFX mod doc for that to make it work better with the PLL, here;

No matter how many times I cut it, it`s STILL too short!
