found this photo from 2007 in a folder on my drive.. was the patch i used to record this piece: soundcloud.com/ava76/buchla-296-buchla-donald
note: configuration has been changed slightly since this photo, now one of 2 original 288s occupies the space to the left of the System Interface.
...its hard to see in this pic but its a hybrid system consisting of 28! Oscillators, Freq Shifter/Bal modulator, 2 Spectral Processors, 16 Lopass Gates, 8 Envelopes, Source of Uncertainty, Voltage Processors, Mixer/preamp, Triple Envelope Follower, System Interface, Time Domain Processor and touchplate. the 300 cpu handles all the sequencing and further voltage processing, multistage complex envelopes.
Q: whats the module left to the system interface?
...its the 298 Silicon cello/sax.. a recreation of the circuit stuffed in the silicon cello... a few were made in 2002 (by me) at the same time as the original run of barberpole modules.
