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 number 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/inverted
• 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
• external AC adapter for power supply (AC adapter for 230V AC, included)
