OSS apps vs. ALSA apps

[raydar]

I finally discovered why I couldn't run Creox and practice guitar using 
Gtick for a metronome: Gtick is for OSS, and it throws up the error

      "Couldn't start metronome. Please check if specified sound device 
and sample file are accessible"

if I try to start it clicking after opening & starting Jack.  Naturally, 
Jack won't start if Gtick is already running.  It looks like installing 
the alsa-oss package is what to do to make Gtick compatible with ALSA 
and therefore with Jack, but I hesitated and thought I'd ask here 
whether there's any reason not to install that package in an Ubuntu 
Studio environment--not sure whether it could interfere with something 
I'm not aware/thinking of.  Am I safe & on the right track?

(If there isn't any reason not to install alsa-oss, then should come 
installed automatically by Ubuntu Studio so that Gtick plays nice with 
all the Jack applications out of the box?)
