Here is a test...
1. Set up your rig so the Legacy is last in the MIDI path.
2. On the Ground Contorl Pro, disable the G-Sharp in Setup Mode by setting the MIDI channel to "--" in the Device list.
3. See if the Legacy 3 responds when only a single MIDI channel is transmitting.
Let us know what happens.
Ok well I just ran this test above and the Legacy did not respond at all to anything. Maybe it is because the Gsharp has a midi out and not a midi thru? So it seems like the Midi Solutions Event Processor will not work on my setup..
another thing i did was to put both on midi channel 1 on this chain and from the GCP the amp tried to change channels as the gsharp changed patches...and oddly enough, if i manually incremented the preset on the face of the gsharp from lets say 01 to 02 and loaded it, the amp would switch to channel 2 as the gsharp would go to patch 2 and so on so forth..
so it looks like i wont have a solution that cleary should be working..
