Can I plug a VC signal into the expression pedal input?
Yes, but there are a couple things you want to do. The range that the SD accepts is from 0V to 3.3V. Don’t let the voltage get above 3.3V. Also, you’ll need to plug in a TRS cable with the RING disconnected. This is so the power that the SD provides on the RING terminal doesn’t short to ground. That would be bad news. Q: I’m having problems saving presets. A: The little black button has to be held down while hitting the preset stompswitch. Some people hit both the black button and the stompswitch at the same time. This won’t work all the time.
