88 Q20 Reference Manual
Selecting Banks via MIDI
You can use MIDI Controller 0 messages to select one of the three Program Banks
(Preset, User 0 or User 1).
Controller 0 messages (like all controllers) can have a value between 0 and 127;
however, a value of 0 will select the Preset Bank, a value of 1 will select the User 0
Bank, and values from 2 to 127 will select the User 1 Bank. If a Controller 0 message
is received followed by a Program change message, the QuadraVerb 2 will respond
by selecting the appropriate Program number in the appropriate Bank.
Note: Controller 0 messages will change Banks only if the Program Change Table is
not being used (MIDI Mode, Page 2).
Program Change Table
Alternatively, you can use a Program Change Table in the Q20 which re-maps
incoming program change messages so that they recall Q20 Programs of a different
number. This is especially useful since MIDI program changes only allow for 128
different programs to be recalled (unless it is proceeded by a Bank select message,
see above). Using the Program Table, you can have any incoming MIDI program
change message recall any of the 300 Programs in the Q20. This is done by assigning
the MIDI Program Change parameter (described above) to ÒTABLEÓ; then select a
MIDI program change number and assign it a Program. Example: If you programmed
the Table so that program message 101 was mapped to Preset 33, and message 102
was mapped to User 0-39, then sending a MIDI program change message of 101 to
the Q20 would recall Program Preset 33, and sending a message of 102 would recall
Program User 0-39.
To incorporate and modify the Program Change Table:
➀ Press [MIDI].
The [MIDI] LED will light.
➁ Press [PAGE >] to access MIDI Page 2.
The display will read:
MIDI PROGRAM CHANGE: O N
➂ Turn the [VALUE/ENTER] knob to the right to set the MIDI Program Change
parameter to ÒTABLEÓ.
MIDI PROGRAM CHANGE: T ABLE
➃ Press [PAGE >] to access MIDI Page 3.
You can edit the program change table, which can substitute alternate Programs
(Preset 00-99, User0 00-99 and User1 00-99) for each of the 128 MIDI program
change messages.
