The MIDI 1U replace the now discontinued uMIDI 1U.
The MIDI 1U is much more compact than its predecessor and with a higher resolution 16bit DAC and a more powerful processor. It has been designed to connect with up to four MIDI Expanders, each offer an additional eight configurable CV/gate outputs. This will allow users an unprecedented amount of flexibility with how they use midi to interface with their modular system! You could potentially have 40 different simultaneous MIDI controls comprising CV, clock, gates and triggers.
