ALM Busy Circuits

Notes: The mmMidi is a simple & compact MIDI interface for your Eurorack synthesiser. It translates two independent channels of MIDI note, velocity and gate information to corresponding control voltage signals via either a classic MIDI DIN type connection or as a driverless USB MIDI device.

The mmMidi also converts MIDI Clock to analogue x24 fixed clock and run outputs (i.e DIN Sync). The optional mmT expander provides a third MIDI channel of 8 key mapped gate outputs.

Requiring minimal configuration and a pain free set up, the mmMidi makes it easy to sync Pam's clock to your DAW, control multiple synth voices, and trigger drum or sample modules with the optional mmT expander. The new USB-C connection makes it easy to drive your modular not just from your computer but also via your tablet, phone or any USB MIDI Host.

(Note: New 2025 mkII version adds USB-C functionality.)
