1. Short description
2. Hardware / Connection
The "µMCLK Divider" module can either work as a MIDI clock divider or as an analog clock
divider. The divider outputs are assigned differently in both operating modes.
After receiving a MIDI start command, the module works as a MIDI clock divider. There are
fixed dividers on 11 outputs. Via the divider output KEYS, triggers can be triggered and mixed
via MIDI notes. The keyboard zone extends over three octaves. With the help of the LEARN
key, the receive MIDI channel and the lowest note of this 3-octave range can be defined.
When stopped (i.e. after receiving a MIDI stop command or after switching on), the module
works as an analog clock divider and divides the analog clock present at the CLOCK input. The
12 analog divider outputs can be reprogrammed via SYSEX. Ready-made SYSEX files are
already available (e.g. for even / odd dividers, Fibonacci series, offbeats, etc.). The RESET
input resets the analog counters or serves to deactivate the analog divider.

2.1 Connection to the euro rack modular system (Doepfer bus)
The module is delivered with a connected
ribbon cable for the Doepfer bus. The red
lead marks -12 volt. Connecting the module
please note the right polarity!
If the module is poled accidentally wrong
safety diodes avoid the immediate destruc-
tion of the module but further damages can-
not be excepted.
So please pay attention: Check the con-
nection various times before switching on!
The current consumption of the module is on
average 50mA, but can reach peaks up to a
maximum of 80mA!
CAUTION!
Do not accidentally connect the MIDI THRU
output to high CV voltages! This can possibly
damage the hardware!

2.3 MIDI connections
The module has two MIDI sockets (TRS-B standard mini jacks) INPUT and THRU. Connect the MIDI
input to the MIDI output of your keyboard / sequencer or computer. The data received at MIDI-IN is
forwarded via MIDI-THRU. Acorresponding commercially available adapter (MIDI-DIN to Mini TRS-
B) or a 3.5mm (1/8 inch) stereo jack cable is used for the MIDI connection.

THRU to other MIDI modules

3. HANDLING
Connect the MIDI input of the module to the MIDI output of a device that can send MIDI start /
stop and clock commands. The device must be able to send MIDI note commands for the trig-
ger output KEYS.
NOTE!
If you only want to use MIDI, do not plug a cable into the CLOCK input (analog divider) or make
sure that no clock pulses arrive via this input. Otherwise the module runs as an analog divider
at MIDI Stop (or after switching on)!
After switching on, the module is in STOP mode. All LEDs are off.
Start a MIDI sequence. When the MIDI start command is received, the module starts as a
MIDI divider and the corresponding rhythms derived from the MIDI clock run at the divider out-
puts. Ashort trigger pulse is generated at the START output. Likewise, all outputs with the
exception of OFFBEATS go on to MIDI start. All outputs with the exception of the 1/32th out-
put and the KEYS output generate a GATE signal with a 50% pulse width ratio. The 1/32th
and the KEYS output generate trigger pulses with a length of 1 tick. However, the KEYS out-
put only generates running triggers as long as one (or more) corresponding keys (Note On)
are pressed via MIDI. > See chapter below!
With MIDI stop the MIDI Divider is stopped and all outputs
are set to zero. There is a short one at the STOP output
trigger pulse generated.
All outputs operate in the voltage range of 0 / + 5V.
3.1 MODE: MIDI-CLOCK-DIVIDER
KEYBOARD/SEQUENCER
7
In MIDI mode, 11 divider outputs have clock dividers that are derived from the MIDI clock. These
are printed on the front panel. Some rhythms have been shifted to create OFFBEATS.
The LEDs signal the rhythms while the MIDI clock is running.
The number of clock pulses is specified in the MIDI standard. One bar corresponds to exactly
96 ticks. The corresponding note lengths (rhythms) are derived from this.
Here is an overview of the specified note lengths:
The 1/32th output and the KEYS output generate a trigger pulse with a note length of one tick.
All other outputs generate a GATE pulse with 50% pulse width.
Name Note length MIDI Ticks
1/2 1/2 note 48 Ticks
1/4th 1/4 note 24 Ticks
1/8th 1/8 note 12 Ticks
1/16th 1/16 note 6 Ticks
1/32th 1/32 note 3 Ticks
TRI/4 1/4 triplet 32 Ticks
TRI/8 1/8 triplet 16 Ticks
DOT/4 1/4 dotted note 36 Ticks
DOT/8 1/8 dotted note 18 Ticks
OFF/4 1/4 note offbeat 24 Ticks (shifted by 12 Ticks)
OFF/8 1/8 note offbeat 12 Ticks (shifted by 6 Ticks)
3.2 MIDI DIVIDER OUTPUTS
If the module works in MIDI divider mode, different clock triggers can be generated on the KEYS
output with the help of transmitted MIDI notes within a 3 octave range. This is comparable to a
DRUM sound expander, in which different drum instruments are assigned to the notes. Different
divider beats are now assigned to the notes. As long as a key (Note ON command) remains
pressed, the beat is output. The trigger beats can be mixed by pressing several buttons. In the
graphic below you can see the preset assignment.
LEARN
You can change the MIDI channel and the lowest note (at which the 3 octave range begins) with
the LEARN function: To do this, press the LEARN button until it flashes. Then send a note from
your connected MIDI keyboard on the desired MIDI channel. This note is then the lowest note
of the 3 octave range. The new MIDI channel and the new lowest note are automatically saved
permanently. The LEARN mode is automatically ended again after receipt of the note (button
LED off).
The default is a note number range from No. 41-76 on MIDI channel 1.

TRIPLETSDOTTEDDUPLETS
If the module is in stop mode (i.e. after switching on or when a MIDI stop command has been
received), the module can work as an analog clock divider. The clock pulses arriving at the
CLOCK input are divided and output at the 12 divider outputs. These dividers are different than
in MIDI clock divider mode (printed dividers) and can also be reprogrammed using SYSEX.
Aspecial feature is that the divider outputs can also be set as an offbeat. The clock output is
shifted by half.
NOTE:
The analog divider works with a rising and falling edge of the input clock. Normally you should
therefore use rectangular pulses with a 50% pulse width, e.g. generated by LFOs. This is impor-
tant for even dividers of odd dividers because they are triggered on the falling edge. But you can
also experiment with different pulse widths and create interesting beats.
RESET INPUT
If the RESET input is high (LED lights up), the divider outputs are set to zero. As long as the
RESET input remains high, the divider output is switched off (all outputs are LOW).

Start/Stop no functions in this mode!
The dividers of the outputs in analog clock divider mode can also be reprogrammed using SYSEX.
Some SYSEX files are available for this. These can be loaded with a MIDI SYSEX dump program (e.g.
MIDI-OX or Elektron C6) from a computer via MIDI. After receiving the SYSEX file, the data is saved
permanently.
NOTE:
You can send the SYSEX files to the module while the analog divider is running. When receiving, the
LEARN LED lights up permanently and goes out again when reception is successful. If the SYSEX
reception was faulty, the LED flashes briefly several times, but the old data are retained.
