I have had some success using just my trusty old Pentium I 166 (souped up with 256 RAM, mind you) and a demo version of Acid Pro 2.0. It takes a bit of tinkering to get completely used to it, and you can only record 8 tracks in the demo version, there are absolutely no effects (not even fade in/out, volume level increase/decrease). However, I've just recently discovered GoldWave, and I think that the two programs combined can be very powerful.
Just a thought...
You can find Acid Pro around the 'net, but beware, my friend recently downloaded version 3.0, and it doesn't allow you to record tracks longer than 2 mins., whereas version 2.0 allows you to record as long as you have hard drive space/RAM. I'm not sure if you can find v2.0 around (I had already downloaded it about a year ago, when it was brand new).
Hope that helps.
see you on the dark side of the moon
