Vintage Synth CPU Updates, Upgrades and Expansions

There are so many CPU upgrades now for our beloved synths of old, that I thought it would be nice to have a catalog of them all in one place. If someone else has done this already, please let me know. Here are a few I can think of. Add new ones below and I will incorporate them into the master list here.

    Hi great list. Found this as it appeared as ping-back on my site..
    I would like to note that the Tubbutec Juno-66 is not only for Juno-60 but for Juno-6, too.
    Additionally there is the Tubbutec ModyPoly for Polysix, Poly-61 and Mono/Poly synths.

    From the Polysix Yahoo group…

    “The KiwiSix is one of two boards I’ve heard of that adds more patch memory. It has 1024, with full MIDI CC and SYSEX support. Johannes Hausensteiner has a MIDI kit that also expands memory to 128. The other various MIDI kits only affect the key assigner board (KLM-366) not the programmer board (KLM-367). The two clone KLM-367 out there (one from Jed and Andy, one from Old Crow) are really clones with no change in functionality. Tubbutec has two kits for Polysix. The ModyPoly adds MIDI, some new unison modes, arpeggiator functions and a Sample and Hold feature for the filter. The PolySex does some interesting pitch modulation with a couple of extra LFOs. The Kenton MIDI kit does note on/off and program change via both MIDI IN and MIDI OUT, as well as patch dump and load (SYSEX) but still with 32 patches. MIDI IN also handles pitch wheel, mod wheel. CHD ELEKTROSERVIS has a MIDI kit that also looks like it handles eight other CC#.

    Did I miss any current kits? Sorry if I gave your favorite kit a less-than-complete description.

    Hi – Thanks for providing this informative and helpful listing!
    For completeness I suggest you add the Korg DW-8000’s Turbo-DW Expansion by Angel City Audio that was once available.
