Problem
Payback is distorted.
Playback is delayed.
Cannot record.
Audio track volume doesn't function.
Pitchbend doesn't work during playback in Sync
Mode
The CBX-D3 does not receive MIDI data.
(The MIDI indicator fails to come on.)
Use high-quality cables for the ANALOG OUT and DIGITAL OUT
connections.
Relatively slow hard disks may introduce noise during playback. If
you are having this problem, try reducing the number of channels
used for playback.
Check for disk fragmentation, and run a defragmentation utility if
necessary.
The CBX-D3 may be receiving inappropriate MIDI messages.
Avoid sending messages that are unrelated to CBX-D3 operation.
Check remaining hard disk capacity.
Check for disk fragmentation, and run a defragmentation utility if
necessary.
Make sure that the SAMPLING FREQ setting is the same on the
CBX-D3 and the controlling software. If after starting up the
controlling software, you change some CBX-D3 settings via MIDI
or another program, the controlling software's SAMPLING FREQ
setting may not match that of the CBX-D3.
Make sure that the controlling software's recording monitor function
is set on.
Check the MIDI cable connections.
Check the MIDI configuration on the application software.
The CBX-D3 disables pitchbend operation during Sync Mode in
order to prevent potential synchronization problems.
Make sure that the controlling software's MIDI configuration is
correct. (The MIDI indicator will light up if MIDI data is being
received.)
