Tuning And Receive Transpose; Bank Select Control; All Notes Off; General Midi - Kurzweil PC88 Musician's Manual

Global Parameters
Merge mixes the incoming MIDI data with the data being generated by the PC88 keyboard and
sends the combined data stream out the MIDI Out jack. Channel numbers of incoming
commands remain intact. Both note and non-note messages are passed normally, but System
Exclusive messages are Þltered out. (The MIDI Thru jack still works normally.)

Tuning and Receive Transpose

Changing the Tuning parameter raises or lowers the pitch of the PC88 by up to a semitone, in 1-
cent (1/100th of a semitone) increments. Changing Receive Transpose ( Recv Trans ) raises or
lowers the pitch a semitone at a time, up to 64 semitones.
The PC88 doesnÕt care which Zone is selected when you adjust these parameters: the whole
instrument changes pitch.

Bank Select Control

Bank Sel Ctl determines how the PC88 will respond to incoming Bank Select messages to
switch among the Internal and the VGM banks. (How Bank Select is transmitted is set under the
Bank Transmit option on the Program menu Ñ in Chapter 5.) Bank Select can be a great source
of confusion, since instruments from different manufacturers may interpret Bank Select
messages differently. This parameter offers the most ßexibility possible, and should be set so
that it agrees with the sequencer or other MIDI device that will be sending the Bank Select
messages. The choices are to respond only to Controller #0; to respond only to Controller #32;
to respond only if both Controllers are sent together; or to respond to either Controller. Note that
if the VGM board is not present, switching a channel to any bank except 0 will render that
channel silent.

All Notes Off

All Notes Off speciÞes how the PC88 will respond to a standard MIDI All Notes Off message
(controller #123). Normally, when this message is received, a synthesizer should stop playing
any notes being held ( Respond ). However, some keyboards (notably those from Roland) and
even sequencers generate All Notes Off messages too frequently, and can cause notes to cut off
prematurely. If this is a problem in your setup, set this parameter to Ignore . In fact, you can
usually set this to Ignore no matter what your setup is: it is quite possible to lead a happy and
productive MIDI life without ever responding to an All Notes Off.

General MIDI

Turning on the General MIDI parameter sends out the MIDI message ÒGeneral MIDI OnÓ to
any GM-compatible synthesizers that are receiving MIDI from the PC88. If the VGM board is
installed, it also puts the PC88 into General MIDI mode, and sets all channels to Bank 1, except
channel 10, which is assigned to a special bank for drums. Turning it off sends out the MIDI
message ÒGeneral MIDI OffÓ. General MIDI is also discussed in Chapter 8.

Device ID

Device ID is a parameter to use when youÕre using more than one PC88 in a system. If you
need to address the instruments individually so that you can dump or load Setups to one and
not the others, then each must have a unique Device ID. The Device ID defaults to 0, but you
can set it to whatever number you want, up to 126. Setting it to 127 invokes a special
ÒbroadcastÓ mode: any PC88 on the MIDI line, regardless of its device ID, will respond to a
PC88 whose ID is 127. The Device ID gets stored as part of the Setup information when you
dump a Setup into a sequencer or other storage device, so when you load it back into the PC88,
