Discussion about the Korg PolySix synthesizer

I did sell a board, to Greg M.   Did your Poly Six vacation in CA?

       Well that's good news.
 Please pardon my ignorance of your device this is for, in
 fact I think my old polysix was midi modd'ed by you Bob
 so i should know this already (i'd bought it from
 someone who had it done by you).. But for what product of
 yours are you referring to? You have a replacement IC6 or a
 whole board?

       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.
