For a long time the BomeBox FAQ used to say that Gamepad and Mouse support was planned for version 1.4.
Now it says this:
This is planned for a future firmware update along with Mouse to MIDI translation.
It is currently at version 1.5.
Is gamepad and mouse support still on the roadmap for the near future?
I was really waiting for that feature.
I read in other topics about MIDIbuddy, that could work for me as a temporary solution.
