The MFB MIDI/CV interface comes equipped with analog outputs for pitch and modulation wheel signals, gate voltages, a clock as well as start/stop pulses. Furthermore, the module features an M-Bus connector. It uses a newly developed, serial protocol (GM norm) to transmit data. The transfer rates of M-Bus are twelve times faster than an average MIDI setup. Besides notes and velocity values, it is also possible to send control data for changing synthesis parameters to compatible modules. – Without any patch cables on the front panels.



The MIDI/CV module offers the following connectors:

MIDI signals are introduced to the module via a DIN connector. Selecting a channel is a matter of seconds, thanks to the learn function.

This connector emits pitch CV signals (1 V per octave). The module is able to generate voltages from 0 V to 5 V. Portamento effects can be created using the glide potentiometer. Data sent by a keyboard’s pitch wheel allows the user to vary the pitch by +/-2 semitones.

Translates data sent by a keyboard’s modulation wheel. (0 V to 5 V)

Delivers gate signals. (5 V)

Start/Stop and Clock:
These connectors offer two modes of operation. They are selected via a jumper on the circuit board.
With jumper: Start = 5 V / Stop = 0 V, 96 PPQ
Without jumper: Start / Stop one pulse each, 16 PPQ

The M-Bus connector can be found on the circuit board of the MIDI/CV module. Compatible circuits can be daisy chained via small wires. The M-Bus protocol always uses MIDI channel 10. Besides notes, velocity values and CC control data are transferred by the protocol.
