Hi,
I'm having a strange issue with my Yocto. It started last week or so. When I switch the instrument select between instruments, the pitch of the CB/CYM/OH/CH goes up and down very slightly. Has anyone experienced this? Any tips where to start troubleshooting?
Thanks!
Instrument Select Changes CB/CYM/OH/CH pitch
Sounds like a short, check the sequencer schematics https://www.dsl-man.de/download/attachm ... 000&api=v2 and check your resistor legs
The issue wasn't instrument select at all. When I switched the instruments, the active button lights were changing per the sequence defined for whichever instrument was selected.. This introduced increased or decreased load on the power supply depending on how many were active. Since the internal PSU I was using was 500mA, it didn't have enough amperage for the circuit, and varyin pitch depending on load was the symptom of the issue. I swapped the 500mA transformer for a 1A transformer and everything is perfect now.
