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) Dimensions: 95 x 75 x 35mm Connections: MIDI input MIDI thru Gate output CV1/2 output (stereo jack) CV3/4 output (stereo jack) 9 V power supply
