As I’m sure most Ion users know, a lot of functions rely on NRPNs. I’m looking at different MIDI boxes to translate CCs to NRPNs in the future. I saw peterpaul’s post about the stereoping controller, which looks cool. Until that time, I thought I would provide the definition file I use that has the few CCs from the Ion MIDI implementation. I hope it helps those with an Ion but no translation box.
