NRPN for Sequencer and parts ABCD

NRPN for Sequencer and parts ABCD
« on: January 13, 2021, 12:27:35 PM »
Hi!
Anyone know what these NRPNís are? Or if they are available at all? Looking for the NRPN for Play on the sequencer and also for parts ABCD if possible. Wanted a hands free midi control option since I play guitar and keys simultaneously.

Works like a champ on my Rev2(the sequencer play NRPNs for Part A and B).

Per the manual, Appendix F: MIDI Implementation, Control NRPN Data section, NRPN 4188 is supposed to be for Sequencer Play/Stop though I didn't see it sent. Or sending MIDI start/stop.

Glancing at MIDI NRPN data from pressing the A/B/C/D buttons, it looks like the following may work:

A   431
B   432
C   433
D   434

When a button is pressed, that one is sent first with a value of 1 then the other three NRPNs are sent with value 0. So, switching to D would probably be sending the following NRPNs:

nrpn 434   1
nrpn 431   0
nrpn 432   0
nrpn 433   0

In case they might be useful:

Seq Mode      nrpn 422   0-2  Normal, Gated, Trigger
Seq Direction nrpn 423   0-3  Fwd, Rev, Fwd/Rev, Random
Slew          nrpn 374   4-5  Off, On


I did notice a possible UI bug after changing the A/B/C/D button selection via NRPN where the previously selected button could not be selected unless you select another first including the one just selected via NRPN. Will need to test out further before submitting as an issue.

Hope that helps.

Jeff,
You are correct NRPN 4188 does nothing via triggered by DAW(logic) or my cymatic LP-16. Whereas, the same NRPN that is specíd for my Rev 2 works flawlessly with the exact same global settings.
Iíve tried everything and no luck getting that sequencer to trigger externally.
