Making connections
- All the connectors described
in this section are to be found at the rear of the REGELWERK.
Power supply
Version with external transformer
- This version of REGELWERK
doesnt have an internal power supply, but is
provided with an external power transformer. The power
supply input socket is labelled '9V DC and is
positioned to the right of the four MIDI sockets and SYNC
socket.
- REGELWERK is switched on by inserting the 9V plug in
this socket, and connecting the mains transformer's plug
to the mains supply. There is no on/off switch.
- Included in the REGELWERK
package for European buyers is a 230V approved
transformer for connecting to the mains.
- For other countries' voltages
or mains sockets, you'll need to buy the appropriate
mains transformer and plug for your country.
- For safety reasons, only use
a transformer and/or plug which has an accredited safety
mark in your country. The transformer output voltage
needs to be about 9V (acceptable tolerance from 7 to 12V)
and capable of delivering at least 500 mA. Polarity needs
to be as follows:- the outer ring is earth / ground, the
inner +7...12V. If the polarity is reversed, the REGELWERK
won't work, but a protection diode should prevent it from
being damaged.
Version with internal 230V mains supply
(not available)
- REGELWERK can't be supplied in the 230V internal
power supply version. Export orders for countries with a
different mains supply from 230V will only be supplied in
the external power supply version.
MIDI connections
MIDI IN connection
- MIDI inputs MIDI IN1 and MIDI
IN2 are used for controlling and synchronising REGELWERK
from a source of external real-time MIDI messages, for
remote control of various functions and effects over MIDI
(fader parameters / special menus etc.), and for the
reception of MIDI SysEx dumps.
- The MIDI inputs have a very
limited MIDI merge capability, in that MIDI data present
at the IN can be relayed to the OUT socket.
- This limited merge function
is only really useful for internal processing purposes in
the REGELWERK, because the presence of large amounts of
MIDI data can otherwise badly affect timing.
- If the data which is being
sent to REGELWERK to control it via the MIDI IN also
needs to be sent completely unchanged to another piece of
equipment, it's advisable to use a MIDI THRU box with the
necessary number of outputs.
- If the data also needs to be
merged with other data before being sent to another piece
of MIDI equipment, then an external merge box needs to be
used, such as the
DOEPFER
MMR4/4
MIDI OUT connection
- MIDI outputs MIDI OUT1 &
OUT2 send MIDI data and realtime messages from the
REGELWERK to the rest of your MIDI set-up.
SYNC Input / Output
- For control and
synchronisation with a typical 'SYNC' square wave signal.
- Depending on the mode chosen,
it can be either an output or an input.
- In normal use, the REGELWERK
SYNC socket is configured as an output, transmitting a
square wave sync signal. The other equipment connected by
the SYNC lead will need to be configured to receive sync
so the REGELWERK will be the master.
- The REGELWERK can also be set
to receive
- a SYNC signal at this socket
(which is now functioning as an input). In this case, the
other equipment has to be set to send SYNC pulses.
- The SYNC signal is simply a
bog-standard square wave, with a range from 0 to 5V.
- That means that a normal LFO
from an analogue synth module can be used as a clock
source. That way, it's possible to relax the tight tempo
of the REGELWERK SYNC signal and produce a syncopated
groove.
- Note that in connecting the
SYNC socket on the REGELWERK with another piece of equipment,
nothing will happen if both units are set to input or
both to output.
CV/Gate connection
- In the current software
version, the 16 mini-jack sockets on the rear of the REGELWERK are
designed purely for sequencer work
- 8 x CV for pitch control
- 8 x Gate
- The CV/Gate option runs
simultaneously and parallel to the MIDI output. Both can
function at the same time. In effect it is doubling the
number of voices that the REGELWERK can control, with the proviso that
the CVs put out convey exactly the same information as
the MIDI pitch and note-on/off data.
- The eight CV outputs are
dedicated to sequencer note information, with output 1
responding to track 1, output 2 to track 2, and so on up
to output 8 responding to track 8.
The respective CVs cover a range from 0 to approximately
5V.
- The response of the CVs is
designed to be exactly one volt to the octave, so that
they're ideal for pitch control.
- The relationship between note
numbers and voltage output is:- note number 36 = 0 Volts;
note number 100 = 5 Volts.
- Notes outside of this range
either below (note numbers 0-35) or above (note
numbers 101 - 127) are folded back to the bottom and top
octaves respectively., and so overlap the response to
note numbers 36-100.
- The eight GATE outputs put
out their respective gate signals whenever there is an
event programmed at the particular step position on their
track.
- For Gate Off, the level drops
to 0 Volts, and for Gate On rises to 5 Volts.
