I'll chime in here. I've been testing Csound5 quite a lot lately, it 
supports PortAudio (as well as ALSA and JACK) and PortMIDI. Frankly, I'm 
not impressed with default realtime performance under PortAudio. I can 
improve performance with some judicious buffer tweaks, but the native 
ALSA driver is much better.

I also agree with Walco re: JACK weight.

Nevertheless, it's Linux, innit ? So you can do what you like... :)

Btw, mimo: Have you tried using Buzz under Linux ? I've had it working 
quite nicely, it's a very impressive program, lots of fun. A native Buzz 
would be most welcome.

Best,
