The recalling of the ROM presets has no effect on the nonvolatile memory (EEPROM).
The preset that you loaded from the editor software into the nonvolatile memory still
exists. To activate it again you must turn the unit off and on again.

For each bank there is one switch and one L.E.D. indicator.
Simply select a bank by pressing either of the bank switches on the Drehbank
.
The Drehbank will then activate the selected bank, which is indicated by the
flashing of the L.E.D. above the pressed switch.

To create a Snapshot you must first press the top switch (labelled snap). When the
switch is pressed for about a second the L.E.D. (that is otherwise inactive except
for Midi activities) blinks rapidly. Press the switch again within a second and a
Snapshot will be sent, indicated by a long flash of the L.E.D. This flash is
important, because if you trigger a Snapshot accidentally ( or at the wrong time)
you could overload the Midi connection.
Once the Snapshot has been sent the Drehbank
returns to bank indicator mode.
Important
If you change your mind and don‘t want to send a Snapshot (or if you go
into the mode by accident) just wait until the L.E.D. stops blinking, (after
one second)
Remember
A Snapshot sends the controller values of all 64 knobs from the active
bank.
L.E.D.s
The L.E.D.s are on the left side of the unit, one above each switch.
They indicate the different operation modes and actions of the Drehbank
.

When the Drehbank is switched on all 3 L.E.D.s light up and stay lit for about 5
seconds. In this time the data from the non-volatile memory (EEPROM) is
transfered to the work buffer (RAM, volatile memory) of the unit. When this is
completed the L.E.D.s switch off and the L.E.D. that indicates bank 1 lights up, as
bank 1 is then active. If this does not happen then either the power input is not
correctly connected to the Drehbank or it‘s possible that the plug or the Drehbank
has a defect.
