11 Troubleshooting
•
If any problems do come up with your
REGELWERK use the following check-list for
fault-finding.
•
It often happens that what look like faults are
actually a product of the operating system
design, which can be avoided or worked
around by knowing the
REGELWERK
thoroughly.
•
If despite careful analysis of what's
happening, the problem can't be overcome,
then there may be a fault in the hard- or soft-
ware.
•
Please in that case approach us or your local
distributor. We will do whatever we can to
help solve the problem as quickly as possible.

11.1 Connection problems
•
REGELWERK is not receiving or transmitting
any MIDI data.
−
Check that the MIDI cables between
REGELWERK and other MIDI equipment are
correctly connected.
−
Check that proper MIDI-compatible cables
are being used. Problems may arise from
using hi-fi or other non-standard cables.
−
Check that there isn't a fault with the MIDI
cables, by substituting cables between
different pieces of equipment. Common
problems are invisible internal breaks in one
of the conductors, or, in the case of home-
made cables, dry or defective solder
connections in the plugs.
•
REGELWERK is not receiving or transmitting
any DIN sync data.
−
Specialist MIDI cables shouldn't be used for
DIN sync, because although the sockets are
identical in appearance, the pin allocation is
different, and pure MIDI cables won't
necessarily work for DIN sync.
−
Also check the DIN sync settings on the
various instruments: if both are set to the
same mode (input, or output) then no
communication is possible. One has to be
configured as an output, one as an input.
11.2 Reception problems
•
Data is being received by the MIDI
instrument, but it's not turning into the music
you're expecting!
−
The receiving instrument is not actually set to
receive MIDI data.
−
The receiving instrument is set to a different
MIDI channel from the one on which
REGELWERK is transmitting the data.
−
The receiving instrument has been effectively
muted by a previous MIDI message (for
instance turning the MIDI volume to 0), etc..
•
MIDI data is being received by the
REGELWERK , but is not being re-transmitted
properly.
−
A different MIDI channel has been selected
for the chosen REGELWERK function.
−
The chosen REGELWERK function isn't
activated, and is set to ‘OFF’, or is set to
respond to the wrong MIDI input.
•
MIDI Events received at the MIDI Ins are
altered before being transmitted at the MIDI
Outs.
−
The MIDI Inputs don't have any built-in merge
function – so incoming data isn't merged with
the
REGELWERK 's internal MIDI data, and
thus isn't available at the output/s. If all that's
needed is to have the data input to the
REGELWERK also available to other devices,
then a MIDI Thru box placed before the
REGELWERK will do the trick.
−
If you want this and other MIDI data to be
merged before being sent to the relevant
instrument, then an external MIDI merge box
like the

is needed.

buttons ‘don't work'.
•
Perhaps all steps are muted, so that although
the sequencer is running, no data is being
transmitted.
•
Perhaps the end step on the selected Track
is set to step 1, so there's no movement from
the Sequencer Step LEDs, and, even with the
Track switched on, no sound, because the
sequence stops moving.
•
Perhaps some parameters (for instance Step
Time, Gate Time, MIDI channel, Note or
Velocity values) are set to extremes, which
can't be recognised by some MIDI
equipment.
•
Electrical storms, power cuts and surges, and
so on, can corrupt the non-volatile memory
