Self-paying on the Buchla 200

"a self-playing patch, using some cybernetic elements:

Two VCOs (258) are cross modulated to produce an evolving sequence of clocks, not just random because the interactive nature of the cross modulation creates unexpected pauses and clusters - the envelope follower (model 230) helps in extracting the clocks. These are sent to an LPG which gates a modulating sound from the 259 - the main tone. The MARF sequences pitches, but these are shifted with a clocked random voltage, changing every 5 or 7 pulses (using the MARF programmable pulse out feature) There are 5 LFOs are all slightly different, and being clocked by more scaled down pulses from the MARF, so the LFOs are locked into the main set of pulses. The signal is split into several paths, one goes to the 277 delay (being modified by the same random voltage mentioned above) and the other going to the spring reverb, also being modified (by an LFO). These also go into 2 bandpass filters, being modulated with row 2 of the MARF. The stereo signal is being modified as well and the whole lot goes into the Buchla 100 signal leveller (model 172) and vintage eq (model 175)
