AVSL 169.011-169.013 MU-series MIDI/USB Keyboard Controllers - Manual (Page 4)

Operation
Connection
The MU-series keyboards can be used directly with a PC or Mac computer to provide MIDI control in a software sound module or
multi-track recording package. For this application, the USB socket on the rear panel should be connected to a spare USB port
on the computer (a USB lead is supplied for this)
– this will transfer MIDI to the computer and provide power to the MU-series
keyboard. The MIDI OUT can also control external devices in this setup.
The MU-series keyboards can also control MIDI devices when not connected via a computer, by connecting the MIDI OUT to the
MIDI input of the controlled device and powering the MU-series keyboard via an optional 9Vdc power adapter.
Assignable Controllers
Press the EDIT button and the EDIT LED will be light to indicate that the note keys are in EDIT mode.
Press the ASSIGN key to enter controller assign mode, the LED display will show CHO, prompting the user to
“choose” the
controller that needs to be assigned.
Operate the required controller to select it (e.g. to assign SLIDER, move the Slider to select it)
The LED display will show the MIDI controller number of the selected controller
Input the desired assignable parameter value with number keys (0-9), and press ENTER to confirm
(e.g. if Slider is selected, input
“1”, ”4”, ”7” and the Slider will be set to MIDI control 147 - Master Volume).

Assignable controller parameters reference: Appendix 2 - Assignable Controller Parameter List.
Pedal Resistance Curve (MU49, MU61)
The response curve of the pedal interface can be tailored to match control pedals with different specifications and electrical
resistance values. This can be adjusted by trial and error, testing the response of the pedal for various values. Alternatively, it
can be calculated as follows…
To calculate the resistance curve value for Pedal A (PA CURVE) or Pedal B (PB CURVE)
Curve = (128 x Pedal resistance value) / (10K + Pedal resistance value).
For example, if the pedal resistance value is 10K, the value of PA Curve or PB Curve is
…
128 x10K / (10K + 10K) = 64.
For the pedal ’s electrical resistance value, please refer to the technical specifications provided by pedal manufacturer. The initial
value of resistance curve is 64, adaptable to most control pedals in the market.
When using a switching type pedal, the recommended resistance curve value is also 64.
When DATA +/- is assigned as PA CURVE or PB CURVE, the DATA +/- buttons can be used to adjust resistance curve values.
Press both DATA + and - simultaneously to set the resistance curve value to initial 64.
When the dials (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 keyboard multi-function mode, press PA CURVE or PB CURVE multi-functional keys to enter pedal
resistance curve adjustment mode, input the pedal resistance value with numeric pad, then press ENTER to confirm.
TEMPO (MU49, MU61)
Press the EDIT button and the EDIT LED will be light to indicate that the note keys are in EDIT mode.
Press the TEMPO key to enter tempo adjustment mode, then input the tempo value with number keys. Press the ENTER key to
confirm.
When DATA +/- is assigned as TEMPO, it can be used to adjust MIDI tempo.
Press both DATA + and - simultaneously to set the tempo to the initial value = 100
Likewise, the dials (R1-R4 or R5-R8) can be assigned to adjust TEMPO
PROGRAM
Press the EDIT button and the EDIT LED will be light to indicate that the note keys are in EDIT mode.
Press the PROGRAM key to enter program select mode, then enter the number with the number keys.
Press the ENTER key to confirm.
When DATA +/- is assigned as PROGRAM, DATA +/- can be used to adjust the program (or voice). Press both DATA + and -
simultaneously to set the program to the initial value = 0
Likewise, the dials (R1-R4 or R5-R8) can be assigned to adjust the PROGRAM number
MIDI Channel
Press the EDIT button and the EDIT LED will be light to indicate that the note keys are in EDIT mode.
Press the CHANNEL key to enter MIDI channel select mode, then set the channel with the number keys.
Press the ENTER key to confirm.
When DATA +/- is assigned as CHANNEL, DATA +/- can be used to adjust the MIDI channel
Press both DATA + and - simultaneously to set the program to the initial value = 0
Likewise, the dials (R1-R4 or R5-R8) can be assigned to set the MIDI channel
