This device solves so many problems that it's almost impossible to list all the uses. If you have any kind of MIDI signal that needs to be converted, re-routed, or re-channelized on the fly, this will do it. I highly recommend getting a powered USB hub because this will allow you to connect an almost unlimited number of USB MIDI devices, and get them communicating with each other without the need for any other hardware. If you want to be really crazy, you can even get *two* BomeBoxes and have them communicate with each other wirelessly - so you can sequence hardware devices that aren't even physically connected. I'm doing just that, and I've even got it programmed (via Bome's MIDI Translator Pro) so that when I play a note on a hardware synthesizer, it automatically arms the appropriate track on a sequencer on the other side of the room. Just amazing.
