Performing (Play Mode)
You can transmit program changes to select sounds on your sound module from the A-PRO.
If you want to select a sound from a different bank, first use bank mode to transmit a bank
select message that will switch the bank. Then transmit a program change message. The
bank select message must be transmitted before the program change.
Here’s how to transmit a program change message on the current channel (p. 42).
1 Use the [ ] [ ] buttons to move the cursor to “PGM CHANGE”
in the display.
The display will show the program change number that was transmitted most
recently.
2 Use the [VALUE] knob to specify the desired program change
number.
The program change message will be transmitted.
If you want to use the [VALUE] knob to switch the bank number, set the System setting
“FUNCTION” to “BANK LSB” or “BANK MSB.”
* For details, refer to “[VALUE] knob Settings” (p. 68).
Here’s how to transmit bank select (MSB, LSB) messages.
1 Use the [ ] [ ] buttons to move the cursor to “USER ASSIGN” in
the display.
The display will show the bank select number that was transmitted most recently.
2 Use the [VALUE] knob to specify the desired bank select number.
Bank select (MSB, LSB) messages will be transmitted.
Selecting Sounds (PROGRAM CHANGE/BANK)
Program change and bank select
By using program change messages in conjunction with bank select messages, MIDI
allows you to select among more than 128 sounds.
To switch to a sound that has the same bank number as the currently selected sound,
simply transmit a program change message.
To switch to a sound that has a different bank number, you’ll need to transmit a bank
number and a program number. The bank number is transmitted using two MIDI
messages: control change 0 (MSB) and control change 32 (LSB). To actually switch
sounds, transmit the bank number (MSB), bank number (LSB), and finally the program
number, in that order.
