The driver had some little changes in version 1.0.8. Additionally,
I've been adding yet another protocol (for MOTU devices), and this
resulted in too many quirky "if"s sprinkled all over the code, so I've
rewritten the handling of the MIDI protocol stuff with callbacks.
I had some code for the Novation protocol for several weeks, but
didn't find any testers who actually tested it -- so you're now my
victim. ;-)
This patch is against the current ALSA CVS. If you modifiy your
kernel, you need only the changes below alsa-kernel/. If you don't
have the CVS version, you can get the patched files from
<http://www.informatik.uni-halle.de/~ladischc/usbmidi.tar.gz>.
Best regards,
Clemens
