yes, it works with the alsa drivers. don't know about oss, but i
wouldn't bother, the alsa support is superior.

no idea.

alsa has worked for me since 0.9.0beta[very early], including MIDI. must
be a config problem on your part.

/dev/sequencer and /dev/midi are oss compatibility devices. all generic
alsa devs are under /dev/snd/ .

get some alsa docs and read from the alsa devices. or take a look at
another open-source app and rip off the relevant code.

here's my setup. i'm using 2 soundcards, but you get the idea.
#generic alsa modules
alias snd-card-0 snd-emu10k1
alias snd-card-1 snd-ens1371
options snd-emu10k1 snd_enable=1 snd_index=0
options snd-ens1371 snd_enable=1 snd_index=1
options snd snd_cards_limit=2 snd_major=116
post-install snd /usr/sbin/alsactl restore
pre-remove snd /usr/sbin/alsactl store
post-install snd-seq /usr/bin/sfxload /usr/share/sounds/sf2/8MBGMSFX.SF2
#this is oss emulation stuff
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-11 snd-mixer-oss
alias sound-service-0-12 snd-pcm-oss
alias sound-slot-1 snd-card-1
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-8 snd-seq-oss
alias sound-service-1-11 snd-mixer-oss
alias sound-service-1-12 snd-pcm-oss
hope this helps,
