Tweaking knob sensitivity via midi_value divisor

[buzkorian]

Sorry if this is poorly expressed, but I don't know all the right words.

I'm looking at the Behringer X-Touch Mini, which I understand has knobs which are not free-spinning but "click" for each fraction of a turn. My understanding is that MIDI2LR assumes each click is intended to move the linked value (Temperature, Tint etc) by a set amount, being 1/127th of the range of the linked value. Another answer says you can control the value of each click by limiting the range (minimum to maximum) of the linked value. However, I understand this means that each click is still a set proportion of that range - that is, (maximum - minimum)/127.

If that's correct, would it also be possible to tweak the value of each click by using a different number in place of "127"? A higher value for finer adjustments, or a lower value for coarser ones?

Is that number something users can set in the options? Ideally you'd be able to adjust it per linked value like you can with min/max values.

Regular controls only send 128 different values (0 through 127) so there's no way to have finer adjustments. It's a limitation of MIDI. There are two ways to get around it:

1. Make the control an NRPN control (some MIDI control surfaces allow that). Then you have 16,384 different values (0 through 16,383), so much finer control.
2. Make the control a differential control. Then MIDI2LR allows you to set the number of steps between min and max. This is because a differential control sends an up or down signal rather than sending an absolute value, so MIDI2LR can use an arbitrary scale.
