So been fiddling around with my new ground control and hooked it to my lexicon mpx 1... everything is working well but i cant figure out how to reach any programs above 99. if the ground control goes in the low hundreds , on the mpx1 it says PROGRAM UNAVAILABLE. Basically right now i can't access program 100 and up, (the user presets start at 200).

How do you send bank change messages from the ground control? Im pretty sure its cc32...

thanks!

The Ground Control Pro does not currently support the MIDI Bank change that the MPX1 requires. The immediate solution is to copy all the patches you actually do use to the User bank and set the MPX1 to pull patches only from the user bank.

I hope that helps!

But the user patches are on 200-250

Does that mean you can't access them???

ouch this is a big problem for me i bought a groundcontrol pro mainly to use with my mpx1

I have not tried this but flipping thru the manual i believe i found the answer, and will post in case any other mpx1 users might have a similar issue.
From the MPX1 user manual , page 5-10, it seems that any program change 0-127 can be mapped to any of the MPX1 250 programs.

System > Midi Maps > then match Map to Program number.

I believe that should be it....

Mapping the presets will work. I believe you can also simply set the processor to default to the user bank so it will simply recall presets from the used bank whenever it receives a Program Change message.
