Possible Cause and Solution
Check that the USB memory device is formatted to use the FAT/FAT32
filesystem, and not set to 'Write Protect' mode.
Disconnect the USB memory device, turn the instrument off then on, then
reconnect the USB device. If the USB device still does not function, it may
be damaged or incompatible. Please try using a different USB device.
This is recognised behaviour when using large capacity (e.g. 8GB+) USB
memory devices.
Possible Cause and Solution
Check that a USB MIDI driver is installed on the computer.
Check that 'USB Audio Device' or 'KAWAI USB MIDI' is selected in the
software's input/output device settings.
Check that the instrument is not connected to a smart device using
Bluetooth MIDI.
Check that the instrument's Bluetooth MIDI function is turned On.
Ensure that the mobile device's Bluetooth function is turned On.
Try deleting the instrument's Bluetooth connection using the mobile
device's 'Forget Device' function.
Try turning the instrument Off and then On, and/or restarting the
mobile device.
Possible Cause and Solution

Check that the format of the audio file is supported and listed in the
'Audio Player supported format specifications' table.
Check that the format of the audio file is supported and listed in the
