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.

Technical specifications

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
