Seems like it might be a power supply issue of some sort.
- I left the midimuso in and removed other modules one at a time. Each LFO I removed decreased the wobble slightly.
- I tried different wall warts. I even swapped for one that was only 1amp instead of two which lowered the pitch and increased wobble. This seems promising.
I use two FC Microbus power supplies per case connected in parallel I think. Each case has one 12V 2a AC AC wart. Perhaps I need to get a better wall wart or explor other power supplies? Ideas?
I suppose I could also separate the Microbus and have a wall wart per bus, but I was hoping to keep it to one power cord per case.
