Re: [PolySix] anyone have an IC6 (key assigner 8049 217) left over from KIWI install?

2015-12-18 by Bob Grieb

You are incorrect in saying that noone has ever extracted the Poly Six key assigner code.
As I mentioned in an earlier post, my PIC code is a direct port of that code.   I take the 8049 instruction 
and map it to the equivalent PIC instruction.   I did have to add a little delay in a few places as the PIC is 
much faster, but aside from that it's the same.   I also added MIDI note on and off, but that was a pretty 
small change.

       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.
