Effect to remap midi notes based on velocity?

I doubt that this exists, but it would be easy to do a JSFX for that purpose. -Michael

It should be possible by using a JS or PizMIDI note filtering plugin followed by JS velocity control. .

I think I can do it with a bunch of copies of MIDI Polyshear (to filter by note and velocity) and NoteMapper (to remap the notes themselves) in parallel, but it would probably be more efficient and easier to modify if I just wrote a script.
