The Top 5 MIDI to CV Converters in 2018

If you want to use MIDI with either pre-MIDI analog synths or with modular Eurorack analog synth systems, you need to convert digital MIDI signals into analog voltages.  Fortunately, there are lots of options. 

We've selected the top 5 MIDI to CV convertors, but there are tons of choices.  The first three are Eurorack solutions.  So you'll need to a Eurorack to use them.  The Kenton PRO SOLO Mk3 MIDI To CV Converter​ is a standalone box so it can be used with pre MIDI monophonic anlaog synths as well as in other studio situations. 


Polyend Poly MIDI and USB to CV/Gate Eurorack Module

 The Polyend Poly module is a polyphonic MIDI to CV converter Eurorack module and is one of the most complete MIDI to CV converters on the market.  It has USB and 5 Pin DIN MIDI inputs and lots of CV outputs

It has three performance modes. First and Next mode are designed for use with an external controller while Channel mode is designed for use with external sequencers or your DAW

  • Polyphonic universal MIDI to CV converter Eurorack module
  • Supports the MPE standard for use with innovative controllers like the LinnStrument, the Seaboard series, and more
  • Inputs include MIDI DIN, USB A (5-volt), and USB B
  • 8 Gate outputs (0–12 volts)
  • 8 Pitch outputs (0–12 volts, V/oct)
  • 8 Velocity outputs (0–12 volts)
  • 8 Modulation outputs (0–12 volts, CC value can be set 0–127 via dip switches on back panel)

Pittsburgh Modular Lifeforms MIDI 3 Eurorack MIDI-to-CV Converter Module

 

The Midi 3 Midi to CV converter has mono and duophonic midi response modes, assignable CC and dedicated velocity outputs.  Monophonic has several different keyboard modes - Last note priority, low note priority, and high note priority and all are available with and without gate retriggering.

Ir also has a built-in Arpeggiator that can be clocked using tap tempo, midi clock, or external gate.with lots of features. . Speaking of the clock, the Midi 3 Module has 3 Clock Modes:

Internal Clock - The Midi 3 clock has a tap tempo button to change the tempo of the internal clock.

External Midi Clock - The external midi clock responds to midi start/stop messages and midi tempo from an external midi clock source. 

External Gate Clock - The external gate clock responds to gate signals patched into the CLOCK jack. The external gate clock is used to clock the arpeggiator. 

ADDITIONAL FEATURES OF THE MIDI 3:

Assignable Midi Channel - The Midi 3 can be assigned to respond to all channels or any individual midi channel.

Assignable Pitch Bend Range - The range of pitch bend can be set to +/- 2 notes, +/- 5th, +/- 1 octave, +/- 2 octaves.

Control Change Output - CC response of 0-5v.

Assignable Control Change Channel Assign - Assign the midi CC channel the Midi 3 responds to.

Velocity Output - Velocity response of 0-5v based on active note. 


Doepfer A-190-4 Eurorack USB/MIDI to CV/Gate/Sync Interface Module

The A-190-4 module offers MIDI In, MIDI Out, USB, CV1, CV2, Gate, Clock, and Reset ports. 


Kenton PRO SOLO Mk3 MIDI To CV Converter 

If you are looking for something standalone that doesn't need a Eurorack ( for example if you just want to control and pre MIDI mono analog synth.  The Kenton PRO SOLO Mk3 may fit the bill. 

Here are the features from the Kenton website.​
