Nice touch on tweakabilty to make this more synth like however changing these pre-set curves in the menu and the EG/Filter dial has little to no effect on some voices. Even the tone dial applies essentially undetectable tonal changes. I would want & hope these parameters would apply pretty drastic changes to the sound. I hope the programming/scale can be improved in an OS update. The more change in tone and parameter with the spin of the dial the better. It's frustrating to turn and press buttons & change values and nothing detectable happens. Super cool that this was included in the YC design but give us more tonal & parameter change please.

Currently the most dramatic changes happen with FM voices which makes sense. Tone still has little to no change. Muffled to very bright would be good for the tone knob.
