Got a call from Paul Maddox - he's involved in organizing the excellent Cambridge Synth DIY meetup - we attended this a few years back (actually it was at least five years!) - it was a blast.
Paul has just made some of his hand built machines available. First up is Zira, a monophonic, 2 Osc synth which uses Korg NJM2069 VCF/VCA filter chips - these the same type used in the Korg DW6000/8000 and DSS1.
Also from Paul (aka Vaco Loco) is the GorF mini MIDI 8 Step sequencer which has just had a fairly major OS update.
AES67 Standard, multichannel playback, record, sync
I guess I've been trying to recreate a Korg Electribe all this time..
