First I would try removing ALSA 0.5. You can always reinstall the debian
packages, but having both installed can lead to subtle errors. It makes it
easier to tell, which library is used and which one is the cause of errors.
I can't say anything to the other sequencers, as I am very happy to use
MusE, the official Debian package at the moment. I also use the Debian
packages for ALSA 0.9 beta10.

The problem is, that MusE, if compiled with ALSA 0.9, can't find the right
libasound, if you have 0,5 installed. That can't be helped with a command
line option, but you might try recompiling MusE from the debian source
packages. It will take a while ;)

Setting up MusE for recording can be tricky and has been a constant topic
on the MusE mailing list. Dave Phillips has tried to put an end to this
with his MusE Quicktoot at http://www.boosthardware.com/LAU/quicktoots/
You should really check this out.

You can build soundtracker without ALSA at all, just using OSS emulation.
That's what I do. I don't use timidity, but you could check out iiwusynth
at http://savannah.gnu.org/projects/iiwusynth. It's a gret midi synth for
soundfonts, and will work with ALSA 0.9

I would try to get MusE working, it's my favourite Midi sequencer. but of
course, I have it running...
