1. Short description
2. Hardware / connections
The "µQMCV" module is a compact up to 4 voice MIDI-to-CV interface with additional CV out-
puts for modulation and pitch bend, as well as two MIDI clock outputs for RUN and 16th clock.
The range of notes is 8 octaves. The MIDI interface is multi-mode capable, which means that
the individual voices can be used separately on different MIDI channels in defined modes in
groups. For example, voices 1-3 can be used in three voices on one midi channel and the
remaining fourth voice can be used monophonically on another midi channel. The module uses
the “Round Robin” algorythm for polyphonic voice assignment.
The module is programmable via LEARN function with a MIDI keyboard or via SYSEX data (via
computer). Some SYSEX files with default settings already exist.
The module has two MIDI sockets (mini jacks in TRS-B standard) INPUT and THRU. The data
received at MIDI-IN is forwarded via MIDI-THRU. Additional MIDI modules can then be con-
nected there.

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 +70mA.
CAUTION!
Do not accidentally connect the MIDI THRU
output to high CV voltages! This can possibly
damage the hardware!

KEYBOARD/CONTROLLER
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 / controller 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.

3. Handling
The module is preset as a four-way MIDI-to-CV interface on midi channel 1. The two controllers
MODULATION and PITCHBEND also work on this midi channel. Send notes from a connected
MIDI keyboard over an 8 octave range of note numbers 12-108. The module can output the
GATE and CV voltages for up to 4 notes at the same time. The “Round Robin” algorythm is used.
If more than 4 notes are pressed at the same time, the last played note replaces the first play-
ed note.
Classic standard connection in the modular system:
Connect the GATE output of a voice to the GATE input of an ADSR generator, the NOTE output
to the 1V / octave input of a VCO and the VELOCITY output to the CV input of a VCA. You need
this four times for all voices.
The CV output MODULATION can be used for filter modulation and the PITCHBEND output for
pitch changes of the VCOs.
How to change the MIDI channel:
Press the LEARN button once (until it flashes). Then send 4 notes in succession on the same
desired midi channel (the GATE LEDs light up in succession when they are received). After
receiving the fourth note, the LEARN function ends automatically (LEARN key stops flashing).
The new midi channel is saved permanently. This now also applies to the two CV outputs
MODULATION and PITCHBEND.

The four voices of the module (each with GATE / NOTE / VELOCITY outputs) can also be used
separately in other defined groups. To do this, the voices must be assigned to other midi chan-
nels. There are 5 modes that can be set with the LEARN function (or via SYSEX):
Aquad polyphon (all same midi channel) -> see also chapter 3.1
BVoices 1-3 polyphonic and voice 4 monophonic (2 different midi channels)
CVoices 1 + 2 duophones and voices 3 + 4 duophones (2 different midi channels)
DVoices 1 + 2 duophones, voices 3 and 4 monophonic (3 different midi channels)
EVoices 1-4 monophonic (all different midi channels)
Note: The voices of the module can only be used in these 5 combinations. So it is not possible
eg. use voice 1 monophone and voice 2-4 in three voices!
How to change the MODE with LEARN:
Press the LEARN button once (until it flashes). Then send 4 notes in succession on the desired
midi channels in the correct order, as mentioned above in point A-E (the GATE LEDs light up in
succession when they are received). The corresponding mode is automatically recognized by
the module. After receiving the fourth note, the LEARN function ends automatically (LEARN key
stops flashing). The new midi channels (and thus the Mode) are saved permanently.
Caution: If the midi channels of the sent notes were sent in the wrong order, the LEARN mode
is aborted with the LED flashing twice. The old settings are retained!
Note: To simplify the operation of the LEARN function, the midi channel of the first voice is auto-
matically assigned to the two CV outputs MODULATION and PITCHBEND. However, it is pos-
sible to set the midi channel of these two CV outputs individually via SYSEX.
Example 1:
With LEARN, send a note twice on midi channel 1, then a third note on midi channel 2 and a
fourth note on midi channel 16. The module recognizes Mode D with the following settings:
- Voices 1 + 2 duphone on midi channel 1
- Voice 3 monophonic on midi channel 2
- Voice 4 monophonic on midi channel 16
- CV outputs modulation and pitch bend on midi channel 1
Example 2:
With LEARN, send a note on midi channel 3 three times and then the fourth note on midi chan-
nel 10. The module uses this to recognize mode B with the following settings:
- Voices 1-3 three-part polyphonic on midi channel 3
- Voice 4 monophonic on midi channel 10
- CV outputs modulation and pitch bend on midi channel 3
3.2 MULTIMODE

The module has two additional CV outputs:
The CV output MODULATION reacts to MODWHEEL (Control Change No. 1) and supplies a
voltage of 0 .. + 5V
The CV output PITCHBEND reacts to the pitch bend wheel and supplies a voltage of 0 .. + 2v.
After switching on, the voltage is set to + 1v (middle position of the pitch bend wheel). If the pitch
bend wheel is turned down, the voltage drops to zero volts, if it is turned up, the voltage rises to
a maximum of + 2v. The module only evaluates the MSB data byte (since most pitch benders
do not use the high resolution).
Midi channel setting:
Normally, the two CV outputs are automatically assigned to the midi channel of the first voice.
However, you can also change the midi channel for both individually using the SYSEX file.
-> see chapter SYSEX
CONTROL CHANGE number setting:
The CV output MODULATION is set to control change number 1. This number can also be chan-
ged using SYSEX.
-> see chapter SYSEX
3.3 MODULATION / PITCHBEND CV outputs
The module has two additional clock / gate outputs:
The GATE output RUN is switched on when a MIDI STARTor CONTINUE command is recei-
ved and switched off when a MIDI STOP is received.
The clock output 1/16th delivers 16th clock impulses which are generated from the received
MIDI clock. The impulses have a duty cycle of 50% (32nd note length). The clock is only output
after receiving MIDI STARTor CONTINUE.
Both outputs deliver approximately + 5v in the ON state.
3.4 RUN and 1/16th outputs

As an alternative to the LEARN function, the module can also be programmed via SYSEX.
Some SYSEX files are available for this. These can be loaded with a MIDI SYSEX dump pro-
gram (e.g. MIDI-OX or Elektron C6) from a computer via MIDI. After receiving the SYSEX file,
the data is saved permanently.
NOTE:
When the SYSEX data is received, the LEARN LED lights up permanently and goes out when
reception is successful. If the SYSEX reception was faulty, the LED flashes several times in
quick succession, it is then not saved and the old data are retained. The reception can also be
canceled with the LEARN key.
DETAILS:
There are three types of files:
Type 1: change all data
Type 2: set midi channel and control change number from the MODULATION output
Type 3: set midi channel from the PITCHBEND output
You can download some ready-made SYSEX files from the FLAME website.
You can also create your own SYSEX files (for example with the freeware program MIDI-OX).
An overview and documentation of the implemented SYSEX data formats can be found in the
next chapter.

3.6 SYSEX Data format
The assignment of the MIDI data for the voices (and thus the multimodes 1-5) and for the two
controller outputs (modulation and pitch bend) can be done with the help of SYSEX data. The
module understands different types of SYSEX files:
Typ 1: SYX file for all data
Typ 2: SYX file for setting the control change number and the
midi channel from CV output modulation
