(up to three octaves in either direction). When you are higher or lower than the

centre octave, the corresponding Octave button will light.

6. Transpose Down / Up: Pressing the transpose buttons alters the musical scale

of the note being played. You can adjust the scale by 6 levels upwards or 5 levels

downwards.

7. Assignable Control Knobs: Each endlessly rotatable knob sends a MIDI CC

message. The Control knobs can also be used for Arpeggiator control when the ARP

On/Off button is pressed and held..

8. Assignable Pads: The pads can be used to trigger drum hits or other samples in

your DAW software. The pads are velocity-sensitive, which makes them very

responsive and intuitive to play. The MIDI message each pad sends can be adjusted

using the Pad Setting function.

15. Keyboard: This keyboard has 25 velocity-sensitive keys and in conjunction with

the Octave Down / Up buttons, can control a ten-octave range.

16. Sustain Pedal Input: Connect an optional 6.35 mm TS sustain pedal to this input.

NOTE: Connect the pedal first before powering on the MIDI controller to ensure

correct operation.

17. MIDI Out: Plug a 3.5mm TRS cable (not supplied) into the back of the MIDI

controller for use with external synthesisers. This controller uses the Type A MIDI

connection standard.

18. On/Off: Slide the ON/OFF switch to turn the power on and again to turn the

power off. The display will light up to indicate power on.

Troubleshooting

Problem

Possible Reason / Solution

The MIDI controller behaves erratically

or its output becomes intermittent.

This could happen if the internal battery

is running low. Please recharge the

device for an hour or so to resume

consistent operation.

When used with a hardware

synthesiser as a controller, the

hardware synthesiser does not respond

to key presses.

Use of incorrect MIDI cable.

Make sure that the MIDI cable being

used is the correct type for the

synthesiser as there are two connection

standards, type A and type B.

The MIDI output messages from the

controller are not as required and you

have lost track of the controller and

PAD settings.

Follow the procedure to reset to default

settings for the Controllers and/or PADs

and then start the customisation again.

The APP running on the tablet device

does not respond to the key presses on

the MIDI controller.

Try exiting or force closing the APP.

Restart the APP and then make the

MIDI connection again either via the

Bluetooth settings in the APP or with a

wired connection.

Bluetooth MIDI cannot be connected

from Bluetooth settings of the mobile

phone or tablet.

This is not a fault. The Bluetooth MIDI

connection needs to be made from the

APP that supports Bluetooth MIDI such

as ‘Garageband’. It cannot be made

from Bluetooth Settings.

The MIDI controller does not respond

correctly to the sustain pedal input.

The sustain pedal was plugged in while

the MIDI control was already switched

on.

Power off the MIDI controller.

Disconnect and reconnect the sustain

pedal. Repower the MIDI controller.
