I've been spending quite a long time attempting to get MIDI support for my music applications with ALSA. I need to say that all these MIDI devices function fine and as they should do on other hardware. The hardware I'm trying to work with is a mid-2009 MacBook Pro, running on Ubuntu 9.04. Now, being a MacBook, it requires some small fixes and tweaks to fully work under Linux, the most important bit for me being sound support. In fact, sound has only worked at all on the latest MacBooks since early August, by compiling, building and installing alsa-utils from an unstable (now stable) snapshot. Luckily, every aspect of sound through ALSA now works wonderfully, and it's only a matter of solving the very last issue, but a big one (as I use Linux as an amateur music production system).
Simply put, MIDI devices are not detected in the audio programs I use, despite being detected at the USB level (as seen via lsusb). I know these devices work with other PCs, but not with my MacBook.
When I compiled ALSA, the ./configure was as follows:
./configure --enable-dynamic-minors --with-cards="hda-intel" --with-sequencer=yes
followed by the usual make and sudo make install. As you can see, alsa is compiled with "with-sequencer" and should surely have MIDI support?
I started trying to add midi-related modules with modprobe, such as snd_seq_device. Here is my lsmod output as I type, and yet with no support for MIDI:

I have no idea where to go from here, as everything should work. But it doesn't. I use LMMS for music production.
Thanks for any help relating to this, it's been a very frustrating issue.
