I'm totally interested in the latency free midi aspect of it, but am unsure whether you can use it as is to control an external synth, it says it has a legacy MIDI port, so it should be possible, but implementation is everything. To write parts into a sequencer without any extra gear or compatibility issues, would also be great, playing VSTis etc. I'll have to read a review in a trusted source first, Sound On Sound or Guitarist, or the opinion of someone on here who has used it. It looks boggin' though, they could make it look sci fi as fuck.
