Version 1.04 Flame Qmcv Module User Manual

Version 1.04 Flame Qmcv Module

Short description

The “µQMCV” module is a compact up to 4 voice MIDI-to-CV interface with additional CV outputs 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 “Voice stealing” algorithm 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 connected there.

Hardware / connections

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 destruction of the module but further damages cannot be excepted.
So please pay attention: Check the connection 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!

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. A corresponding commercially available adapter (MIDI-DIN to Mini TRSB) or a 3.5mm (1/8 inch) stereo jack cable is used for the MIDI connection.

Handling

Quad MIDI-to-CV Interface

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 “Voice stealing” algorithm is used (for 4/8 voice mode “Round robin” from V1.04). If more than 4 notes are pressed at the same time, the last played note replaces the first played 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.

MULTIMODE

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 channels. There are 5 modes that can be set with the LEARN function (or via SYSEX):
A quad or 8-fold polyphon (all same midi channel) -> see also chapter 3.1
B Voices 1-3 polyphonic and voice 4 monophonic (2 different midi channels)
C Voices 1 + 2 duophones and voices 3 + 4 duophones (2 different midi channels)
D Voices 1 + 2 duo phones, voices 3 and 4 monophonic (3 different midi channels)
E Voices 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 automatically assigned to the two CV outputs MODULATION and PITCHBEND. However, it is possible 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 channel 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

MODULATION / PITCHBEND CV outputs

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 changed using SYSEX.
-> see chapter SYSEX

4 RUN and 1/16th outputs

The module has two additional clock / gate outputs:
The GATE output RUN is switched on when a MIDI START or CONTINUE command is received 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 START or CONTINUE.
Both outputs deliver approximately + 5v in the ON state.

8voice MIDI-to-CV Interface

Two modules can be used in parallel as an 8voice MIDI-to-CV interface. One module takes over the first 4 voices and the second module the second 4 voices. They must be set to mode-A/A and mode-A/B using SYSEX commands. The SYSX files (QMCV_Poly_8voiceA.syx and QMCV_Poly_8voiceB.syx) can be downloaded from the FLAME website. In addition, both modules must work on the same MIDI channel. This can be set easily with the LEARN function for the 4voice mode: Connect both modules via THRU. Then activate LEARN on both modules (press the button). Then send a note four times in a row on the desired MIDI channel. Both modules are now set to the same MIDI channel. -> see chapter SYSEX

Note:
The voice assignment algorithm for 4voice and 8voice mode is “Round Robin” from version 1.04.

fach Interface

Settings via SYSEX files

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 program from a computer via MIDI (e.g. PC with “MIDI-OX” or “Elektron C6”, MAC with “SYSEXLibrarian”). 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
Type 4: set polyphonic mode 4voice /8voice-A /8voice-B (since version 1.04)

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.

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

output
| | (range: 00=CCnr 0 .. 7F=CCnr 127)
0000xxxx| ccch| 1 data byte MIDI channel of Modulation output

| | (range: 00=channel 1 .. 0F=channel 16)
11110111| F7| End of Exclusive
(total 13 bytes)

Typ 2: SYX file for setting the control change number and the midi channel from CV output modulation

output
| | (range: 00=CCnr 0 .. 7F=CCnr 127)
0000xxxx| ccch| 1 data byte MIDI channel of Modulation output
