That is weird - they responded me pretty quickly, like less than a day. I have been assuming the audio quality will be top-notch, I guess because the rest of the design is strikingly no-compromise. I mean, that line of thinking worked out with Norns 
That said, I haven’t played on any of their other consoles so I can’t speak to experience. Also, the placements of what appear to be the start and select buttons are going to be problematic for e.g. LSDJ.
Yes, oh my. I’m not as familiar with what can be done with FPGAs - can you build, say, filters in them? At any rate there’s got to be some interesting possibilities with a MIDI controller.
I’m becoming a bit addicted to these weird little computers. The pocket / handheld / battery-powered music options are amazingly richer than they were just a couple years ago, and they weren’t too shabby then either.
