MIDI CONTROLS

Rotary Encoders
Turning an encoder produces
M I D I C C ( c o n t i n u o u s
controller) messages with a
unique controller number in
‘Two’s Complement’ binary
encoding. Refer to the
MIDI
C O N T RO L S E C T I O N
(p25)
for the differences
between Map 1 and 2 for these
controls.
These encoders feature a
built in momentary push
switch. Pressing down on the
encoder knob activates the
switch and sends a ‘Note On’
MIDI message, releasing the
switch sends a corresponding
‘Note Off’ message.
