modulation, but the expression pedal can also be assigned to 
control any other knob parameter.
• MIDI: MIDI control mode. Select to enable MIDI I/O through the 
Soundblox 2 MIDI Interface

EXP mode, Hot Hand defaults to modulation or is assignable to 
any knob parameter.
CONTROL ASSIGN
By default, the expression pedal and Hot Hand inputs control modulation. 
This can easily be changed to control any of the adjustable knob parame-
ters. To assign control to a knob parameter, follow the instructions below:
1. Select the desired external control option: EXP for expression 
pedal, HH for Hot Hand.
2. Press and hold the CONTROL INPUT button (A) until the LED 
begins to blink slowly.
3. Set the low position of the desired knob, for example SPEED (B), 
to the lowest setting you would like to use.
4. Press the CONTROL INPUT button again, the LED will now blink 
more rapidly.
5. Set the desired high position you would like to use.
6. Press the CONTROL INPUT button to complete the assignment. 
The LED will blink 3 times to indicate the process is complete.
Note: Different control assignments can be programmed to a preset. 
Don’t forget to save your settings!
