How do I change my drum "set" / "kit"

Sorry if this has been discussed elsewhere but I cannot find any info in any of the forums.......
In a nutshell. I am using Musescore 2.0 on Windows 7.0 laptop with Jack Audio plugin to re-direct MIDI out
from Musescore into Kawai MP6 keyboard MIDI in. Works great! But now I am trying to go one step further and
switch drum kit(set) from the "standard kit" (patch 1) to "jazz kit" (patch 33). I believe this has to be done
using an external "program change" MIDI message sent to the Kawai from Musescore/Jack. (I'm not sure,
I'm not a MIDI expert and the Kawai MP6 users manual is sparse to say the least). I don't think I can
change the patch using any buttons on the Kawai keyboard itself and I wouldn't want to do that anyway since I would want to probably change back and forth remotely anyway.

Thanks for any and all help or pointers to more information to research to get this to work. I'm probably
missing something really basic. Thank you for your patience.
