PC
88
(If there isnÕt one, it just shows a number.) HereÕs an example of the PC88Õs display when you
press the
<<<
key while an internal voice is active:
You can set the Bank by any of the usual data entry methods, Direct or Intuitive. Like Programs,
any Bank can appear in any Zone. For example, turn the alpha wheel one notch clockwise
while the above is displayed to see:
Zone:1||||||1:001
Bank:General|MIDI
Notice that the Bank number and name change, but the Zone number and program number donÕt.
Sending Bank Select Messages to External MIDI Devices
Bank Select messages can go to external MIDI devices as well, if the Destination is set
accordingly. Some instruments have more banks than the PC88: the Kurzweil K2000, for
example, has 10. The MIDI SpeciÞcation says a device can have up to 16,384(!) Banks, and the
PC88 gives you access to every single one of them. Bank switching over MIDI makes it easy for
the PC88 user to scroll through sounds on external instruments, no matter how many Banks
they might have.
If you select an empty Bank (like Bank 1 if you donÕt have the VGM board; Bank 4 if you do),
the Zone will produce no sound on the PC88, but will still send MIDI data out. The Program
display will say ÒExternal Program,Ó indicating that any sounds produces will be created by an
external device. If the Bank parameter is showing on the display, instead of a name you will see
some numbers, in the display below, for example: Ò292 (2/36)Ó.
Zone:1|||||292:049
Bank:292||(2/36)||
The Þrst number is the Bank number and the ones in parentheses show the Bank number in the
two-byte form (Most SigniÞcant Byte (MSB) followed by the Least SigniÞcant Byte (LSB))
prescribed by the MIDI SpeciÞcation. The Bank number is the MSB multiplied by 128, plus the
LSB. If this is confusing, donÕt worry Ñ weÕll discuss what it means shortly.
Press the right cursor (
>>>
) to return to the Program menuÕs program display. From the above
display, for example, pressing
>>>
would change the display to this:
Zone:1|||||292:049
049|External|Prog|
From this display, use any data entry method to change the program number.
Entry Transmit
The next parameter on the Program menu (press the right cursor button, twice if you have to) is
Entry Transmit
. If it is set to
On
, then whenever you select this Setup, the program number
assigned to the Zone will immediately be sent out as a Program Change command on the
ZoneÕs MIDI channel (assuming that MIDI is one of the destinations). When it is
Off
, no
program change is sent from the Zone when the Setup is called. A Bank Select command may
or may not accompany the Program Change, as weÕre about to see.
