Changing the key of the harmonizer with NRPN (midi Raw)

  • Hey,


    I own a kemper stage for one year and an half, and I use set list maker to send midi programme change to my kemper so it allows me to change my rig and my performances as I change my songs to the app (by creating midi presets). I also use a bluetooth midi device (yamaha mbt01) between my ipad and my kemper, instead of a cable, and fopr that purpose, everything work fine.


    Here is my setup:
    Ipad -> bluetooth midi device from ipad (and the app) -> Kemper in
    Kemper out -> Roland GR 55 in
    Roland Gr55 out -> bluetooth midi device from ipad (just to give the power to this device, as the midi out of my kemper is already connected to the roland GR55 in).


    My question is how could I change the key of the harmonizer to each song (midi preset)?


    I know that setlist maker could use raw (NRPN) midi as well as my kemper. But I'm not really familiar with raw midi :


    What do I need to write exactly to make it work?
    I find some stuff like that to a former thread in this forum (which I no longer find) , but I don't know what it means exactly:


    B0 63 32 // dec 50

    B0 62 40 // dec 64

    B0 06 00 // dec 0

    B0 26 02 // dec 2


    Any idea?


    Thanks :)


    Sincerely


    Thomas
