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:

➀Press [MIDI].

The [MIDI] LED will light.

➁Press [PAGE >] to access MIDI Page 2. The display will read:

MIDI PROGRAM CHANGE: ON

➂Turn the [VALUE/ENTER] knob to the right to set the MIDI Program Change parameter to ÒTABLEÓ.

MIDI PROGRAM CHANGE: TABLE

➃Press [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.
