At the high school attending I'm the main sound guy of the tech team. We had a bunch of old studio equipment lying around: enough to create some decent demo recordings in my spare time. I borrowed a G5 iMac from the tech class, as it would already have some loaded software for me to use. It has Garageband 3, which is an easy solution, but our older teacher had purchase Cubase SE 1 a while back but it never really got used. Would a much older version of Cubase, with all of its VST-Compatibility and advanced i/o architecture, be a better choice than a recent version of apple's consumer-level music production software?

Keep in mind that I am currently using a 2-input audio interface and I am not doing incredibly large tasks with it. Although I'd like to get everything I can out of it.

Thoughts are appreciated :D
