non-programmable button.
The only limitation of MIDIScope is that it can display only one message at a time. Therefore it
can be confusing if you are sending multiple channels of information at the same time. If you are
testing the PC2 itself, itÕs best to mute all the zones but one so that you can see what info that
zone is sending (or you could use the Solo button). If you are testing info coming from an
external source, such as a sequencer, you would also want to mute all the tracks but one.
If you suspect a physical problem with the PC2, you can use the diagnostics to test it.
