JLCooper FaderMaster Pro - Manual (Page 73)

Troubleshooting
If you experience operational difficulties, take some time to do
some troubleshooting, starting with the following information.
First, disconnect both MIDI cables from FaderMaster Pro.
If the problem goes away, then it is likely that you have a MIDI
loop.
You may be able to solve the problem by only working with a
cable connected to FaderMaster Pro's MIDI out.
If you need to have both the MIDI input and the output
connected, then try some of the recommendations in the
chapter on using the Automation Bank, specifically on pages
45 and 46.
If moving the faders appears to result in no MIDI data being
sent, remember that in the Automation Banks and fader must
be enabled (turned on) before it will send MIDI.
In the P Banks, make sure that you have not set the MIN and
the MAX for the same number.
If the unit behaves erratically, you may have unstable power.
FaderMaster Pro, like all microprocessor-based equipment
(keyboards, computers, signal processors, etc.) requires very
clean power for reliable operation. At least use a power
outlet strip with both surge suppression and line
filtering.
Also, static electricity has been known to cause problems with
electronic equipment, especially in air-conditioned studios.
Products such as Static Guard are inexpensive and effective,
and may save you money in repair bills.
