Troubleshooting
Symptom:
The B4 software does not follow to the parameter changes of the d3c and does not respond
to preset changes triggered by the d3c (Bank/Number buttons). If one or two d3m keyboards
are used the B4 does not respond when keys on the d3m are pressed down.
Solution/explanation/reason:
Midi Out of the d3c has to be connected to Midi In of the computer.
The Midi Output interface of the B4 has to be routed to the right port and to be turned on.
Symptom:
No feedback to the d3c when a parameter or preset change is triggered in the B4 software
Solution/explanation/reason:
Check the Midi connections: For this even Midi Out of the computer has to be connected to
Midi In of d3c (directly or daisy-chained via one or two d3m).
The Midi Output interface of the B4 has to be routed to the right port and to be turned on.
For the complete dump during a preset change in the preset menu of the B4 software the
function "B4D Controller Dump on Program Change" has to be active (available from version
1.1.5)
Symptom:
When the preset is changed in the B4 software the d3c parameters are updated (LED
settings change) but the correct preset number is not displayed (i.e. the settings of the
Bank/Number LEDs remain unchanged).
Solution/explanation/reason:
Unfortunately some versions of the B4 software do not transmit a program change message
when a new preset is called up. Consequently the d3c does not "know" the new preset
number as the corresponding information is not sent by the B4 software. The only solution is
to update the B4 software to a new version.
We ask for your understanding that we cannot give assistance to the correct installation of
the computer's operating system, the computer's Midi interface and the B4 software as these
things depend on the individual hardware and software components of each computer.
