Encumbered in terms of patents or something? This would be an issue for all of the design. Not only need we design it, but to some extent we need to make an effort to ensure that the preamp design doesn't step on a patent, etc. > > For me this would be most useful as a portable i/o, so I'd want a few > analogue ins and outs. Mic preamps would be good, but not essential. I think I mostly agree, but I probably have two uses - portable where I want some preamps and in the studio where I want to connect to other PCs. > > Personally I would be willing to pay over the odds for something like > this, particularly if it had a bit of spare FPGA space that could have a > DSP unit blown on it, or whatever. I'm not sure but I thought there are some FPGAs out there now with processors already in them. DSP I'm not sure. However it's nigh on impossible to do 1394 or USB without at least a small microcontroller so I think we'd be looking at some form of a processor somewhere.

More D/A & A/D though. Can sends and returns be lower quality or does everything need to be consistently good? I have no opinion right now... > > > MIDI? > > Ideally.

Probably anyone who wants MIDI has a solution long before this unit shows up anyway. - Mark
