We reviewed the Monotribe from Korg some time back and one of our criticisms was the difficulty in playing the thing via the fiddly touchstrip keyboard. However, one of the plus points was also the user modification potential, should one choose to get the screwdriver out and get busy with the circuit board.
Amazing Machines have capitalized on this and designed the MIDITRIBE IO a retrofit board (we inderstand its a simple job to install), which adds both MIDI in and MIDI out. We have a willing Monotribe here and are awaiting delivery of the kit as we speak. In the meantime, here's a teaser image that was supplied by Amazing Machines over the weekend.
