Thanks Florian,
I'm actually expecting the DIY arp to be a difficult situation but one worth pursuing, albeit with some patience and no guarantee it'll end up working.
My setup has changed and i'm gearing up to abandon computers and midi altogether. To play the arp, i'll be wanting to create a miniature keyboard using dozens of small momentary buttons, and then (and i know this might be tough) have the output of the arp able to go to monosynth cv/gate. It would of course be nice to be able to have the output be switchable between V/oct and H/V, but V/oct would be preferred if only one. However is that's accomplished, external conversion would be possible at that point.

When i used the arp on the polysix, i almost always just set the synth into "monosynth mode" which was just by using the chord function for just one note. Then it would only ever trigger the same voice over and over. So this would be the goal for the diy arp circuit, to create a purely trigger/cv/gate situation but only ever for one voice at output. I don't even have a poly synth anymore.

And as for the tuubutec arp situation, and others, i'm pretty sure that the IC6 program information has never been extracted by anyone. So all of the arps out there are approximations, probably including the korg plugin. They may be close, and probably all awesome in their own regards. And maybe i'm naive to think that the original is superior since i haven't actually used the Kiwi/Tubbu/etc versions and they definitely have wonderfully committed designers behind them. But it's worth trying to resurrect an original since i'm already in love with the darn thing. call me a romantic.

Hello J,

you are of course right about how wonderful the arpeggiator in the P6
is, but still there is the question: what soundgenerator do you want to
control with it? You have to rebuild the complete Voiceboard including
the VCOs!

The CPU and the D/A converter output a multiplexed "nearly V/Oct"
voltage without any trimming. If you control a normal CV-Synth with this
voltage, it will sound like "cats chant" (german saying). The trimming
happens within a common exponentiator for all voices and then is
demulitiplexed as six V/Hz voltages. The VCOs of the P6 are V/Hz (this
is, why the P6 is that amazing stable in relative tune).

If you want the P6-Arpeggiator and want it to send MIDI-NOtes, then get
the tubbutec CPU for the P6 (https://tubbutec.de/modypoly/). You may use
it nearly standalone and it will send the Arpeggio via MIDI-Out and(!)
will read the notes from MIDI-In.
