The indicators show which bank is active:
- L.E.D lit over Bank 1 (Bank 2 off) indicates BANK 1 is active.
- L.E.D lit over Bank 2 (Bank 1 off) indicates BANK 2 is active.

Once the snapshot switch has been pressed the L.E.D. above it blinks rapidly. By
pressing the switch once again within a second a „Snapshot“ will be sent and this is
indicated by the L.E.D staying lit (again for about a second). After this the L.E.D.s
returns to bank indicator mode.

Under normal operating the L.E.D. which indicates the Snapshot mode is switched
off. For that reason this L.E.D. ( top ) is also used to indicate Midi events.
The L.E.D. flashes for every activity on the Midi bus (both Midi In, and Midi Out).
Midi events are normally performed very quickly and therefore the flashing of the
L.E.D. is hardly noticeable. Turn a controller and watch the glow of the L.E.D.
The indicator also shows if a control knob is sending an event. Also you can see, if
the Drehbank is receiving Midi data.(e.g.the receiving of information from the
editor program.)
M I D I T R A N S F E R E R R O R S .
If the Drehbank experiences an error in the receiving of data, the unit will turn the
bank indicator off and switch on the Snapshot L.E.D. which will flash continually.
Despite this the
Drehbank unit is still operational. By pressing the Snapshot
switch you can reactivate the Bank and Snapshot indicators.
Note
Under normal operating conditions this error should not occur.
Non volatile memory/presets
When you turn on the Drehbank without going into the editor program you’ll find
several complete presets already available.
These are:
- The Fixed ROM Presets, which are found on the EPROM, with the operation
software of the Drehbank, but this can only be altered by updating the
EPROM.
