To rapidly scroll up or down, press and hold the selected footswitch. Once the MIDI channel has been selected, press any footswitch to exit.

Continuous Controller Mode

The Control 8 can also operate as a continuous controller. To use the Control 8 as a continuous controller, you must first put the unit in continuous controller mode. This can be done by pressing the <2> and<Down> footswitches at the same time. The program number can be changed using the<Up/Down> footswitches. The

current program number is displayed briefly, then the CC indicators are displayed. The numbered footswitches are now used to turn the CCs on and off. Now press the <2> and<Down> footswitch to return to program mode.

The Control 8 will allow you to select CC number values by pressing the <0> and<1> footswitches at the same time to enter CC pedal select mode. Now press the<Up> or<Down> footswitches to move up or down. To scroll up or down faster, press and hold the<Up> or<Down> footswitches. To exit this mode, simply press any one of the numbered footswitches. The value is now stored into memory.

Program Selection / Program Mode

The Control 8 operates in banks of ten. The far right LED bars in the display indicate whether you are in the lower 5 or upper 5 programs in that bank. To choose a bank, press either the <Up> or<Down> pedal. (MIDI Channel select is between 12 and 0). In a bank, notice that either the lower bar or upper bar is lit in the display. Therefore, if the display reads 6, and the upper bar is lit, the programs selected will be65-69.

When a program change message is sent out, the display will flash 4 dashes. To increment or decrement Banks quickly, press and hold the <Up> or<Down> footswitches. The numbers will change slowly at first, then scroll rapidly.
