Discussion about the Korg PolySix synthesizer

Big project.   You might contact the people who are selling 
KLM367 replacement pcb's to see if they will let you use their
artwork, or maybe just buy that board from them.  It's very 
reasonably priced.

I have PIC code that replicates the function of the key assigner 
MCU and adds Note On/Note Off MIDI.   I can let you use that 
if you want, for your own projects, but not to sell.

The Electric Druid web site has an implementation of an SSM envelope
generator chip using a PIC chip.   Maybe it's the same SSM used in the Polysix?
But you would still need the SSM filter chips, right?

       Hello All,
 I have just joined the
 group. Its great to see there's a worldwide community
 for the Polysix.
 On the other hand the big
 attraction of that vintage machine, has
 let the price explode within just a few years.
 Hard to get a hand on one below 1000
 Euros these days.
 I own already a couple of
 POLY 61 which can still be got around 200 Euros,
 which is a very reasonable
 pricing.
 So while I cannot afford
 the tag for a full Polysix, I've got
 plenty of 2nd hand components to make synth of my own, and i
 thought
 Why not build a Polysix
 clone from scratch?
 Some may think I am crazy?
 But why not?
 When you have a database of
 all PCBs with schematic and
 layout,it's a piece of cake to
 replace one CPU by another, add mods, hacks, MIDI etc,
 without ending in a mess of cables and
 PCB stacks..
 I am skilled in using PCB
 schema and layout design.So I got
 schemas and layouts of KLM 369, 370, 371 already
 together.
 Now I want to get going
 with the bigger PCBs. However what I
 need are good quality photos of existing PCBs from above and
 from below.In addition I've need a
 scan of a SM where the PCB traces are resolved better than
 on the copy that I have.
 So if the one or other of
 you had such photo or scans, I would be more than 
 happy.
 If someone was interested I
 will for sure share my layouts and schemas with
 you.Native format is TARGET3001,
 which you can get for free as pin-limited
 version.
 Cheers,
 Tarek
