Using CV sequencer with FV-1
What would be the best way to use a sequencer's cv to control a pot input on the fv1? dont want to exceed 3.3v but the sequencer I have puts out 5v. Im worried that a voltage divider will not supply a constant 3.3v depending on the dc adapter the pedal is plugged into.
A voltage divider is not a bad way to go. You could use an opamp with a gain of about 0.66 to scale 0-5V to 0-3.3V, etc. Really as long as the power supply goes through regulators to give you a nice 5V and 3.3V it shouldn't be an issue.

The POT inputs will actually max out slightly lower than 3.3V so target a 0 to 3.1V range.
While transients slightly above 3.3V should be OK you do not want to run any continuous voltage above 3.3V. Better to run a lower voltage and if necessary scale up the POT value in code.
