• SWING: 50% (no swing), 55% , 57% , 59% , 61% , or 64% ( 50 - 75% using the control knob).
• MODE: The mode setting determines how the arpeggiated notes are played back.

UP - Notes will sound from the lowest to the highest.

DOWN - Notes will sound from the highest to lowest.

INCL (Inclusive) - Notes will sound from the lowest to the highest, and then back down. The lowest and highest notes will sound twice at the directional change.

EXCL (Exclusive) - Notes will sound from the lowest to the highest, and then back down. The lowest and highest notes will sound only once at the directional change.

ORDER - Notes will sound in the order they were pressed.

RAND (Random) - Notes will sound in a random order.

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.
