devices such as a sound module to send out MIDI data via MIDI output port.
 KS25B can also be used standalone when connected to an optional 9V DC power supply. In
this case the MIDI data will only be sent out via the MIDI output port.
3.3. ASSIGN CONTROLLERS
 Press EDIT button to enter keyboard multi-function mode, the indicator of EDIT is on. Press
ASSIGN button to enter controller assignment mode, LED shows CHO, reminding the user
to choose the controller that needs to be assigned. Operate the very controller to select it (For
example, if you want to assign SLIDER, slide the Slider to select), the LED shows the
controller number of the selected controller, input the desired assignable parameter value
with numeric pad, and press ENTER to confirm (for example, if Slider is selected, input 147
and the Slider is assigned as Master Volume Controller).
 Assignable controllers reference: Appendix 1- Assignable controller List
 Assignable controller parameters reference: Appendix 2-Assignable Controller Parameter
List.
3.4. PEDAL RESISTANCE CURVE
 You can adjust the pedal resistance curve to better adapt to pedals of different specifications
and resistance values.
 Estimate resistance curve: Value of PA Curve or PB Curve=(128*pedal resistance value) /
(10K+pedal resistance value). For instance, if the pedal resistance value is 10K, the value of
PA Curve or PB Curve is: 128*10K/(10K+10K)=64.
 For pedal resistance value, please refer to the technical specifications provided by the factory
 The estimation of resistance curve does not have to be very accurate, or you could just adjust
it without calculation, as long as the travel and succession of the pedal satisfy your needs.
 The initial value of resistance curve is 64, adaptable to most pedals on the market.
 When you use switching type pedal, the recommended resistance curve value is 64.
 When DATA +/- is assigned as PA CURVE or PB CURVE, DATA +/- can be used to adjust
resistance curve values. Press two buttons of DATA +/- at the same time to restore the
resistance curve value to 64.
 When the knobs （R1~R4 or R5~R8）are assigned as PA CURVE or PB CURVE, they can be
used to adjust pedal resistance value.
 Press EDIT button to enter into keyboard multi-function mode, press PA CURVE or PB
CURVE multi-functional keys to enter into pedal resistance curve adjustment mode, input the
pedal resistance value with numeric pad, then press ENTER to confirm. (KS49/61)
3.5. TEMPO
