Also, your questions are a bit broad in focus. Tell us what you're trying to do and what you're currently trying to do it with.

I don't know of a Mac version of Acid. However, there are tools like [[url=http://[/URL]="http://www.propelle…"]"ReCycle"[/]="http://www.propelle…"]"ReCycle"[/] that serves a similar function in a more basic and less elegant way.

I don't use ProTools so I don't know the best soft synths for that particule platform. However, many manufacturers of software synths offer limited-function demos for you to "try out" before you make a buying decision.

The electronic keyboard companies with the best sounds would be Hammond, Fender, Hohner and Moog.

err...all kidding aside, that's a bit like asking what company makes the best beef jerky. Meaning, only YOU can make that determination and its very often more than one company.

Good luck, as always, Google is your friend.
