Good freewares, hard to find. But one thing I find amusing is, you are not cheap enough to break the rules, yet you are cheap enough not to buy a software.
This is where people can say, money means more than character.
Anyways, back to the topic. Krystal is better compared to Multi-Track Sequencer but neither are good. I use Adobe Audition. It is great, and very easy to use (and fast as well). Nevertheless, I think its better if you take the money and buy one of the great software such as Adobe Audition.
