Flogging this horse stillBut as I got my old Edirol UA-3d working with plan9 again (i.e. I plugged it in!) I thought I'd see what the USB audio landscape looked like, my it has changed.
Has anyone tried one of these with plan9 http://www.roland.com/products/en/UA-101/ It also does MIDI which is something else I'd like to play with.
