I would dearly like to see a midi insert effect where you could set a velocity curve to filter velocities.
Its main use would be to adjust the action of a under or overly sensitive midi controller keyboard, but it would have other uses as well. Not all controllers have this setting.
At the moment you can use logical editor to aproximate some of the common curves, but its a bit of a pain to do, and it’s nowhere near as useful as having a fine grained and user friendly beizer curve implementation.
Bonus points for including a “pitch curve” secondary layer - but maybe that’s asking too much
