OK on quick glance the libdssialsacompat package appears to 
 include the necessary functions as well.
Freebsd uses OSS essentially.

This is bizarre. Why include a special ALSA package just for dssi?
I mean you either support ALSA or you don't.

However Flo I do see your point about decoupling from ALSA.
Let Jack and OSS handle it there. 
All round excellent goal we've all agreed.
Don't worry we'll get there I hope, and be one of the few (only?) fully 
 Jackified sequencers supported there.

Hey let's write an OSS driver! Ha ha ha. Just kidding. (Again, sarcasm.)

So to install MusE with DSSI one would need DSSI and this compat package.
Weird. Hope it fully has what we need, but it seems OK.
