Cat Girl Synth CGS58 Utility LFO and two CGS34 Analog Shift Registers in one module. The addition of Loop and Series switching on the dual ASR's was a fun logic exercise.
At the time of video posting, the module still has a few bugs. One of the registers is glitchy and produces a short voltage burst occasionally. The Looping function layers the last voltage onto the next sample causing a linear rise in cv pitch, which is probably a switch logic problem. Otherwise the module works pretty well.
The series switch sets up a six register round. The channel A LFO pulse is forced to the channel B side for this keeping everything timed. The Loop function also works with/without the Series and was a major hurdle to make work together - logic wise.
I added the Hi/Lo speed caps to get the range broader on the LFO. I also added a mute switch for each register stage on the ASR's.
A fun project but a time consuming and challenging build for my level. The module is 3 spaces wide in 5U MOTM format. The depth behind the panel is 3.5 inches (89mm). Pretty tight.
This thing is a vco eater. I used eight vco's in this demo. Two for the LFO and six for the ASR's.
Thanks for watching and commenting.
