Velocity Expansion

[ferro4prez]

Hi all! I'm just looking for a quick dirty fix for my midi controller's limited velocity output. Literally, if someone can help me write a little JS snippet that maps velocity from (20-110) to (10-127), I'll be the happiest of campers.

I did the math, and the function f(x) = (13x - 160) / 10 will linearly accomplish this.

Could someone tell me what JS code would take the input velocity value, and times-it-by-13-subtract-160-all-over-10, then spit it back out at this remapped velocity ?


The ultimate version of this would let you type in your controller's lowest and highest possible velocities, and let it remap it to (0-127) or whatever you choose, automatically. I'll be happy to just get mine working in the meantime though

THANKS!

Try this.

EDIT: If you have time, try the second one and see what you think.

My god man, THANK YOU! This does precisely what I need!!! I really appreciate your help with this, my controller feels as close to a real piano as I think possible. I'm positive that many people would get so much use out of these scripts, in particular the one that allows you to input ranges.


All the best!

Sorry for un-dust this old thread. Is there some updated or new midi tool(s) for replace this dated 2014 or it is still fine to use? I can't found velocity input transformation in ReaControlMIDI.

Thanks in advance.
