I've seen
the BFC-2000 looks promising but why an USB interface anyway?
I have a BCF-2000 and am very satisfied. It has a MIDI IN/OUT/THRU and
usb connectivity. The usb is a standard midi device and thus works out
of the box with alsa drivers. And you can access the midi port via the
usb in both directions, thus you have a nice usb-midi interface for free.
May I ask what you use this for under Linux? Is the use of the faders
supported by any apps today?
Thanks!
