A high res control mode you can enable in global settings. 1024 values instead of 128, for all the controls. Like on a Korg or other modern analog synth with a digital control interface. The staircase effect when slowly changing a parameter sounds very cheap. The synth already has 14-bit MIDI, so it would be super easy to implement. Otherwise, how about releasing the firmware open source like the Linnstrument bravely did?
