MidiCV 63B

4 channel MIDI to CV converter

The MIDICV 63B module is designed for accuracy, low latency and simplicity of operation, while maintaining a wide range of features in a single width panel.
There are Midi to CV units available from other manufacturers that may offer a broader range of settings and features but as with many such designs they can be obscure and difficult to access and setup. We intentionally set out to create a simple no-nonsense design with preset modes or setups to cover the essential Midi to CV functions suited to a modular system.
The resulting streamlined design is extremely fast with no perceptible latency when played from a keyboard. A high resolution 16bit DAC is used in conjunction with precision low-drift components and temperature compensated voltage reference providing excellent linearity and tracking outputs. The accuracy is measured at better than +/-0.01% (+/-1 cent) over the 10 octave range.
