If yes, how do I do that? You can specify an alternative installation directory at configure time, I think, using the option --prefix=/usr/local/bin/audacitycvs/ or whatever. > Is there some way to store my old Audacity version in a safe > place so I can go back to it if things don't work out with the > new version? If you have your original Audacity binary in /usr/bin then it shouldn't be affected by having a binary in another location, as far as I can tell. I once had one version in /usr/bin and another in /usr/local/bin and it worked OK. > Are there are any project data incompatibilities with previous > versions of Audacity? There have been some reports on the audacity-devel list of problems with projects going between 1.2.1 and CVS versions, as I recall. I wouldn't use the CVS version for serious work - it's just too untested. > I'm really looking forward to a JACKable Audacity.

I tend to be quite conservative with the software on my studio machine because reliability is all-important. Last time I did a professional recording job, the mixing desk power supply failed at the end of the last session, but the Linux box ran perfectly! Cheers Daniel
