Control Change Modes
The AN1x has two Control Change modes. Mode 1 is the
official MIDI standard, which is set at the factory. Mode 2 is
a special list of Control Change parameter settings unique to
the AN1x.
To change between modes, first turn off the power. Then,
press and hold [ASSIGN] and press the [POWER] switch.
Either “mode1” or “mode2” will appear in the LCD at the
start-up procedure to indicate which mode is activated.
When using Mode 2, take care when making Control Change assignments
since the behavior will be different from the MIDI standard.
For a list of Control Change types for each mode, see the separate Data List
book.
