Thanks guys! I actually tried j2a but now i realise that i forgot the -e option to expose the hw ports. Doh! I'll give it another try tonight. Thanks!

FFADO is a backend that you can run JACK on top of. If you run JACK with the FFADO as the "driver", then JACK will be able to send MIDI commands to your Saffire. ALSA MIDI is a totally different "MIDI". The upside: There's a program "a2jmidi" which will put all your ALSA MIDI ports into the JACK MIDI graph, then you can connect any ALSA MIDI out to JACK MIDI in, and vice versa. "a2jmidid" is the name of the package on debian based systems. Running is usually most benificial like so: a2jmidid -e & so that it keeps scanning the ALSA MIDI graph for changes, and will update the JACK MIDI ports available. Good luck! -Harry On Thu, Dec 8, 2011 at 9:57 PM, thijs van severen <thijsvanseveren(a)gmail.com> wrote:
