I strongly advise using "Jack" as the audio engine in Ubuntu.
I thought Jack was ("only") a sort of "virtual audio cable" for connecting the output of an app to the input of another. I guess it is _also_ that.
Anyway, just out of curiosity, why cannot two pd's using oss or alsa both work simultaneously while other apps apparently can?
Thanks
