The mail lady just delivered my Cocoquantus!  I’ve only just started playing with it.  Here’s my first recording.  I created a simple drone patch using one Buchla 258J VCO, modulated by the dual XR-2206 VCOS with the sine and waveform outputs patched through a pair of Haible Trapezoid VCAs in self-cycling mode.  These are patched into the Cocoquantus, which is recorded.  I manually operated the COCO delays and did not use the Quantussy Oscillators.  The recording starts out dry, you just hear the patch.  Then I bring up the delay feedback and shortly afterwards start messing with the delay frequencies.  Wild.
