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 2 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.

Module Highlights:

• 4 Pitch CV outs 0-10V
• 4 Gates +5V or +10V user selectable set by jumpers
• 4 Continuous Controller Outs 0-5V
• 12 modes of operation (see list below for mode details)
• Pitch bend combined with note pitch on all 4 channels
• Sustain pedal is combined with gate data on all gate outs
• Panel adjustment of Pitch Bend amount
• 2,3 and 4 note polyphonic modes with poly pitchbend
• Pitch range of 10.5 octaves with +/-1 Octave pitch bend
• Arp Style Duophonic mode with improved playability over the original
• 16 bit high accuracy DAC (INL = +/- 3LSB (+/-0.0005V)
• 4 x LEDs for gate status and binary mode indicator (Green)
• 1 x Midi activity indicator LED (Red)
• Midi Clock out divided to 1/16th note for external syncing
• Base Channel switch selectable between Ch1-4 or Ch5-8
• Midi In and thru jacks
• Added Multiple section to utilize panel space
• Low current consumption 65mA@+15V, 10mA@-15V
