Hey there,
The CC97 and 98 NRPN are not required to make this work, the BeatBuddy is automatically set to incr/decr via CC:106 and CC:107 tempo MSN/LSB, but you may want to set them to CC:106 and CC:107 after having set it to CC:0 and CC:32
From BB manual:
Steps to Increment Tempo
| Steps | Message | Details |
|---|---|---|
| 1* | CC:99 / 106 | Set the NRPN MSB register to Tempo MSB |
| 2* | CC:98 / 107 | Set the NRPN LSB register to tempo LSB |
| 3 | CC:96 / 1 | Increment the tempo by one |
Steps with a * are optional if the only value control by Inc/Dec is the Tempo. By default, the BeatBuddy will increment / decrement the tempo when receiving a INC/DEC message.
After doing this you can also use CC:97 to decrement by one (or by whatever value used in CC:97)
Hope this makes sense,
Thanks for the question!
