second, you maybe have to setup some things while on both sides:
1) on the arduino pots side: assign each one a different MIDI CC perhaps--i don't really can't help you here, as I don't even know what the so called "Leonardo" thing is :)
2) on the synthv1 front side (or any of the v1's for that matter): go into menu Help > Configure > Controllers and map those MIDI CCs to one and each of the knobs by symbolic name; one better and friendlier way is right-clicking on the target knob you wish to control, set to its "MIDI Controller..." and there you can even catch up while turning the arduino leonardo controls (pots?), provided it's connected all through alright.
hi, first make yourself welcome
