I want to try input an external LFO to the FV-1. Could this be done using one of the POT inputs?

Pretty sure that's possible, although there is a bit of a time lag due to filtering of the POT inputs. Somewhere around here there is a bit of code to increase the responsiveness to the POT inputs.

Yeah you can do this, just make sure your LFO is limited to 0 to +3.3 Volts. Like Larry said there's some lag due to the filtering on the pots, which can be improved with the "fast pot" code he mentioned. The filtering also limits the maximum frequency to a few Hertz, I can't remember exactly what, it's been a while since I tried it.
