Example use of the Modular Tetrazzi as a sound generator, driven by other modules. In this patch a simple pattern generator drives four MOTM-800 envelope generators, each of which is patched to one Tetrazzi VCA input.  The inverted out of the MOTM-800 came in handy to drive two of the VCAs panning in the opposite direction.  The pattern generator clock also drives three sample and holds, which patch to the four Tetrazzi VCO CV inputs.  With that running I played around with the UPTON, DONTON, UPMOD, and DONMOD pots, and flipped the range switches.  The recording is straight from the Tetrazzi VCA outputs.  No other processing!
