Can somebody point me the way to the digital music forums with more users?

Depends

I like the Ableton and Logic forums at their respective sites cuz that's what I use.

check out bigbluelounge.com (nee osxaudio.com).

check out http://www.taperssection.com

no real history with it, in fact, just noticed it from a post below, but they seem to have useful discussions going on...

If you use Logic, logicprohelp.com.

The admin on there, David, is a beast. He knows everything.
