Digitone - NRPNs and Ratio Offset Control

Hello all,

I’m trying to setup a controller to be able to modulate the Ratio offsets on the DN. The MIDI implementation shows NRPN information for the four offsets but, being new to NRPNs, I cannot figure out how to actually setup my controller. One thing I’m hoping to clarify is:

  • The ratio offsets do not have any CC values, only NRPN values. Can they be controlled if they don’t have an associated CC value? It would be really odd to even publish NRPN values if they are devoid of CCs (and they are required).

I just want to confirm that you can even control the ratio parameters externally or if I’m just wasting my time going down this rabbit hole.

Cheers!

Yes, possible to control with CC just need 3 CC slots.
NRPN MSB (CC 99) with value 1
NRPN LSB (CC 98) with value 95-98 for offsets
Data Entry (CC 6) with the actual value for the offset

Cheers! I’ll see if I can translate this onto my Grid controller. Curious, where does the MSB value of 99 comes from? Is that because the last LSB value is 98?

Edit: I see now where 99/98 come from after reading this article:

Edit: Worked like a hot damn. Big thanks!!
