I was able to recreate a similar patch to the ones I’ve used in recent performances, but with the inclusion of the second 259 which wasn’t available to me in the small performance configurations from a few weeks ago at Invent Room Pop and the Pre-INC show.
The rhythmic pulse is the mod osc of a 259, filtered, and with it’s waveshape altered via (CV) feedback to a spike, with a QRV source occasionally bouncing it into the audio range. The other half of this 259 becomes the audio FM source to inputs of another pair of VCOs from a single 259 (both using the square outputs), all three of which share pitch inputs that have emanated from a single source but each with different conditioning.
The Monitor line – with all three VCOs (the FM prin osc not making it into the final mix) enabled – is fed to the preamp and then sent to one half of the 275, which then is sent to a centered channel on the 207.
The 281 and 257 provide some activity for the 266 to feed on, and also each help with the signal levels on the 292 (the 281 via an OR).
