You can use the multimix with AMS but, I don't think you will be able to multitrack. Don't slam Cubase LE it is slightly limited but there are some aspects of it that you will appreciate as opposed to Acid. One being, the ability to punch in. In Acid, every take results in a new track, which can be both a pain and a strain on your cpu. Another thing is the ability to use sends in LE which is another potential strain on your cpu when using Acid. Learn LE it's a great program. SE is only $150.00cdn, $99US. Cubase Studio 4 is only about $400.00 All of those allow you to multitrack. SE is an awesome deal for it's ability and far more capable than most home recordists will ever be able to take advantage of.

thanks for the reply, I'm glad to hear good stuff about Cubase Le, it seems good. I was just curious if i'd be able to still do things in acid, but im gonna ditch acid and go with cubase.

I still use acid for loop based stuff. It works well for that. Especially for assembling a back beat. If you have a good loop library it saves a lot of time on drum programming. And it supports odd and multiple time signatures. A great tool. Use them both.
