8-channel high-precision MIDI-to-CV converter
μMIDI MONO·8·16·MONO·A is a monophonic MIDI-to-CV converter in the form of a compact micromodule, offering eight high-precision control voltages plus GATE and CLOCK signals. The module is designed to translate the complete set of control signals produced by a MIDI keyboard into control voltages for an analog synthesizer. In addition to PITCH, GATE, VELOCITY, AFTERTOUCH, PITCHBEND, MODULATION, and SUSTAIN messages, which are handled by default, 3 user-selectable CC controllers may be assigned to three auxiliary CV channels. The device receives MIDI signal through standard, disturbance-safe UART (DIN) input, what also simplifies integration with user circuits including digital part. Thanks to the on-board 8-channel 16-bit analog-to-digital converter, the module offers eight CV outputs of uncompromising accuracy with output voltage step being at the level of 0.3mV! This allows to achieve pitch voltage precision of less then 2 1 cent and full 14-bit resolution of control voltages, even when the output range is reduced to 14 of the maximal one.All CV outputs except PITCH may be configured to generate control voltage in any range within the limits of −10V ÷ +10V with the choice of 5 response curves and polarity.
The 1V/Oct PITCH output range is 0÷10V , what translates to 10 octaves, with additional possibility to choose the lowest C note corresponding to 0V. Hz/V pitch voltage standard is also provided.
A unique feature of uMIDI-MONO-A is its ability to generate pitch voltages corresponding not only to the most commonly used tempered intonation, but also to 12 natural intonations. There is more: the user may define up to 3 custom intonations, by adjusting the CV curve in arbitrary way, even for each separate note in the whole keyboard. Custom intonations may also be used to adjust the PITCH output for a specific voltage controlled oscillator in order to compensate its nonlinearity.
