Description

maaping function

LMMS has a placeholder for this, but it's not functioning since I'm using LMMS (version 0.4.5).

I'm starting to think about creating a live set for performing with a band and LMMS seems like the best option. Yet it'd be great if I could transform the input values.

Right now when I assign a CC control to a plugin dry/wet control I get:

0..127 = -1..1

I'd like to be able to make it:

0..127 = 0..1

I can do this within my MIDI controller, to make a knob send out signals in range 63..127 , but it'd reduce my precision twice, and if I want to control multiple parameters in different instruments with one knob, it'd be lacking flexibility.

What do you think?

Research direction

No source file, test, or entry point is named in the issue. Start by locating the controller mapping implementation and determine how plugin dry/wet controls currently convert MIDI CC values; done means supporting the requested 0..127 to 0..1 mapping without reducing controller precision.
