3.2. CONNECTION/POWER/CONTROL
üKS25A/49A/61A gets connected to PC via the USB cable. This connection powers
the keyboard and is used to transfer the MIDI data to PC. In addition, you can
connect to other devices such as a sound module to send out MIDI data via MIDI
output port.

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).
üAssignable controllers reference: Appendix 1- Assignable controller List
üAssignable controller parameters reference: Appendix 2-Assignable Controller
Parameter List.
3.4. PEDAL RESISTANCE CURVE
üYou can adjust the pedal resistance curve to better work with pedals of different
specifications and resistance values.
üEstimate resistance curve value: 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.
üFor pedal resistance value, please refer to the technical specifications provided by
pedal manufacturer.
üThe resistance curve estimation does not need to be very accurate, or you could
simply adjust it without calculation, as long as the travel and succession of the pedal
satisfy your needs.
üThe initial value of resistance curve is 64, adaptable to most pedals in the market.
üWhen you use switching type pedal, the recommended resistance curve value is 64.
üWhen 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 set
