Allen Organ Company Protege C-19C User Manual page 26

Therefore, it is possible that a MIDI device that is only High Bank or Low Bank
compatible, to have 128 BANK Numbers, each could contain up to 128 voices/sounds,
for a total of 16,384 sounds. Think of these BANK Numbers as floors or stories in a tall
building. Each floor would contain 128 rooms and each room could then contain 128
voices!
There also are MIDI devices that are High Bank and Low Bank compatible. It
therefore, would be possible for these MIDI devices to have as many as (128 X 128 X 2
= 32,768 voices/sounds) 128 voices/sounds in each of the 128 BANK Numbers, in each
of the High and Low Banks. Most MIDI devices do not use all of the locations
available. It would be very expensive as well as difficult to remember the address for
each sound location.
Some MIDI devices offer only General MIDI sounds/voices. These General MIDI
devices may operate using High Bank or Low Bank but only the sub-group Ø Bank
Number is used to store the 128 General MIDI sound settings.
Allen Organs are able to access any of the Banks and therefore are able to communicate
with all MIDI devices.
NOTE: You MUST know the capabilities of, and understand how to operate, any
MIDI device you intend to use!
SELECTING HIGH BANK or LOW BANK:
Advance to the window function "MIDI Base Channel" (See Section A-2). It will
display: "MIDI BASE CH: X" along with the current BANK pointer. Using the
CURSOR button on the Console Controller™ place the cursor on the second line after
the word "BANK". Turn the ROTARY DIAL to select either HIGH or LOW Bank
priority.
SELECTING MIDI BANK NUMBERS: Applicable for some models)
Bank Numbers are able to be assigned the same way MIDI Program Numbers are (See
Section C-3); except you must only select from the Divisional Pistons. Using a BANK
Number to select an external MIDI Device sound/voice, can be done from any of the
Divisional Pistons. You must have "USER" mode selected as the program change
mode (See Section C-2)
Advance to the MIDI Program Change window function (See Section A-2). It will
display: "MIDI PROG CHANGE". For this example press the Great Division Piston 1.
The display will indicate that Great Divisional Piston 1 has been selected and the current
BANK number assigned to that piston. The window also displays the current MIDI
program number assigned to that piston. Using the "CURSOR" button place the cursor
on the first line of the display after the word "BANK:". Turn the ROTARY DIAL to
raise or lower the bank number. A bank number (0-127) will be transmitted on the
channel assigned to the division from which you selected the piston; in this case, the
Great Division on Channel 2. (See Section C 1). Once you have assigned a MIDI BANK
Number to a piston, that number will remain assigned to that piston even if the organ has
been turned off.
