uMM

2x Midi Merge & Midi Thru plus trs A/B Converter

With uMM, Flame has created a slim MIDI artist equipped with 2x MIDI Merge, 2x MIDI Thru as well as a trs a/b converter.

uMM can act as the central MIDI control unit for your entire setup. With an ARM processor for plenty of power and a whole bunch of MIDI ports, you have everything you need.

The MIDI merge section, for example, allows you to use a main sequencer and a MIDI keyboard together to control all your synthesizers! You studio heroes and live artists alike will benefit from this.

The second section of uMM consists of two 1 to 3 MIDI-Thru units. Plug one output into the input of the other and you now have 1 to 5 Thru at your disposal!

flame uses midi trs b, but there's also a trs converter on board.
