Trouble Shooting - Kurzweil PC88 A Step By Step Manual

PC88 Made Easy

27. Trouble Shooting

If you run into problems while playing or programming, there are several things you can
do to help troubleshoot the problem.
First of all if you are not getting the expected results from your programming or are
having strange results when hooked to an external device, you can use the MIDIScope
utility to see exactly what MIDI messages are being received by the PC88Õs sound engine.
Press the Global button, the press >> until you see MIDIScope. (Or you can hold the >>
button and it will quickly scroll through the parameters.) Then press Enter. The display
says ÒMIDIScope Any Button QuitsÓ. Now the display will show EVERY MIDI message
that the sound engine part of the PC88 receives, whether that message comes from PC88
itself or from the MIDI In Port. You will see exactly what type of message it is along with
the value of that message. For example, a note on message will show you the note
number, along with the attack velocity. A controller message will show the controller
number along with the controller value. It also shows you the MIDI channel of the
message. To leave MIDIScope, j ust press any button on the PC88.
The only limitation of MIDIScope is that it can only display 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 PC88 itself, it is 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 PC88, you can use the diagnostics to test it.
The diagnostics are covered in Appendix G of the manual.
