Hiya!

I just received my 8820 and I am currently "evaluating" it in serious games 🤣
The INST MAP button on it is great to hear differences as it changes maps on the fly without doing a reset. After looking at the manual here I see that you can send a SysEx message to change the Instrument map with it:

Needless to say I don't fully understand the procedure... Anyone here knows what SysEx message is the "bank select MSB and program change" one so I can edit it and add one of the values from the first image?
Thanks in advance for any help!
