Installation is clearly laboring under Xp, patch, which are added galore, run "parallel" for all its mahcines in stereo, you name it, it really is not "plug and play". Special mention to fixkit, that confuses more than a beginner (though, it saves the skin more than once this app: D).
Big problem of incompatibility with XP, so we must go out that we vet to run the machine in compatibility mode Win 98, then, it should roll.

Once you go, the more particular problems.

SUITABILITY/PERFORMANCE

On my Xp1800 +, 768 ram and Tascam us122 / SBLive with Kx drivers, it will run without any problems, a true small rolls.
The stability of the soft itself is perfect, some machines are fleet GAINST Avoid like the plague.

OVERALL OPINION

I use it extensively for 2 years and I can not do without. Of course, Buzz has faults, unmanageable for some, I understand very well, but once settled, well it sounds, simply.
You can do everything with Buzz, really. Some machines are beautiful and make the shadow made a point of view of the very expensive plugins.

In short, a killer, just a little hard to handle.
