MCV4 is a budget-priced
MIDI-to-CV-Interface to control vintage monophonic synthesizers
via MIDI. MCV4 is provided with 4 analog control voltage outputs
(CV1...4) and one Gate/Trigger output.
- 4 analog control
voltages CV1...CV4
- voltage range for
CV1...4: 0...+5V, 8 Bit resolution (equivalent to 1/4
semitone resolution)
- CV1 for pitch control
(normally VCO CV)
- CV2...4 for voltage
control of other functions (e.g. VCF frequency, loudness,
modulation)
- MIDI control of
CV1..4:
- CV1: note
on/off with pitch-bend, 1V/octave characteristic
- CV2 monophic
after-touch
- CV3 velocity
and/or volumen (controller #7)
- CV4 velocity
and/or any controller (setting of the
controller-no. via learn button)
- pitch-bend is used
for CV1 generation with 1/4 semitone resolution
- gate output type can
be selected via jumper inside the device between voltage
trigger (+5V or power supply voltage) and S-trigger
(switched trigger)
- MIDI channel and
reference note for CV1=0V adjustable via learn button
- different assign
modes for CV1 (highest note, last note, reference note)
- retrigger on/off
while playing legato
- gate/trigger polarity
normal/invertet
- two 1/4" stereo
jack sockets for CV1/2 and CV3/4
- 1/4" mono jack
socket for gate/trigger
- learn button with LED
for adjusting MIDI channel, reference note for CV1,
controller for CV4
- optical display of
gate/trigger via LED
- MIDI-In, MIDI-Thru
- non-volatile memory
for parameter settings
- orange-red metal
case, approx. 95x75x35 mm
- external power supply
7...12V/100mA required

Remarks:
MIDI channel, reference
note for CV1 (this is the MIDI note corresponding to 0V of CV1
and thus the lowest possible note of the analog synthesizer
connected to MCV4) and the controller no. for CV4 are adjusted
via learn function. For this the learn button must be pressed and
the required MIDI messages sent from the MIDI controlling device
(MIDI synthesizer, keyboard, sequencer ...). The other parameters
(retrigger, trigger polarity, assign mode ...) are adjusted in
learn mode via program-change messages.
The Hz/V mode available in the predecessor model MCV1 is not
available with the MCV4 because of the many problems occuring
with the non-linear Hz/V characteristic. But some synthesizers
normally using Hz/V can be be controlled with V/Oct (e.g. Korg
MS10/MS20, details you may find in the MCV4 user's guide).
If you want to use all 4 analog control voltages you need 2
special cables with a stereo 1/4" jack plug on one end (MCV4
side) and two mon 1/4" jack plugs on the other (synthesizer
side). You may get such cables from your local dealer but we also
offer such a cable (MCV4 cable 1/4" stereo - 2x1/4"
mono). If you need it we recommend to order it together with the
MCV4. Same applies to the power supply. We offer a power supply
that can be switched between 230V and 115V.
For more details you may
look at the English User's Guide of the MCV4. Here you will also find some
hints for connecting the MCV4 to specific synthesizers like Moog
or Korg MS10/20.
