Sub 37 MIDI Commands - How to use NRPN

Post by CJDeegan » Sat Oct 31, 2015 2:19 pm

Hey there I am seeking help on the mystery of NRPN messages. I am using my MP-201 pedal to send MIDI to my Sub 37 but don't know how to send NRPN messages when the MP only does PC and CC. Specifically I just want to utilize ARP STEP 1 RESET (Value Range = 2/ NRPN=416/ NRPN MSB=3/ NRPN LSB=32) to stay in time with a live drummer. How can I accomplish this?
Thanks a lot for any feedback!!

Admitted I have done a lot of this and definitely never done it for this specific NRPN:

You'll need 4 CC messages to send an NRPN message

99 3 - this tell the synth you want to send an NRPN message (99) and the message you want to send is identified with MSB 3 (ARP STEP 1 RESET - MSB 3)
98 32 - this tell the synth you want to send an NRPN message (98) and the message you want to send is identified with LSB 32 (ARP STEP 1 RESET - LSB 32)
6 0 - data for the NRPN message MSB - since this message only has a range from 0-2 this will always be 0
38 2 - data for the NRPN message LSB - the range for the ARP STEP 1 RESET is 0-2 so this could be 0, 1 or 2. I'm not sure what the 3 different values represent.

If this doesn't work, try swapping the 0 and the 2

Good luck.
