Description

This utility maps common expression CCs found on MIDI controllers to script-specific OSC params on Monome Norns. It properly supports scaling both on the MIDI input end (integer values from 0 to 127) and the OSC output end where values are floats and can have different ranges, say, panning between -1.0 and 1.0 but filter cutoff from 0.0 to 5000.0.

The defaults are set up for Awake so you can test it right away after adding it to your project. But of course, any OSC parameter in a Norns script will work. To discover what names they have, go to PARAMETERS on Norns, select MAP, and find the parameter you like.

You address the parameter by its name prepended with "/param/". For example, in Awake you'd go to PARAMETER > MAP > halfsecond to find "delay_rate". If you want to use it with the MIDI mod wheel, put "/param/delay_rate" as the parameter name in the MIDI to OSC plugin.

This was inspired by my MIDI CC to MIDI CC translator:

and the global OSC parameter editor for Norns:
