how does this work?

hey everyone.

i am new here, and i didn't know where to post my question, so i picked this forum. sorry if i sound like a newb.

i bought ACID Pro 5 about 3 years ago and got a lite version of FM7, B4 and PRO-53 included with it. i never used them because i didn't have a MIDI controller. i did a lot of drag and drop stuff with the ACID files, and never thought about the keys stuff because of the lack of controller.

last year i bought Battery 3 (again bought without controller) and just last week, i fixed the no controller problem and bought an M-Audio Axiom 49.

i thought about it, and decided to install the 3 synths, and the Axiom controls them quite nicely. my question is, how do i get them to open in Pro Tools (i also just upgraded to PT 8) or ACID for that matter? i can get ACID and Battery to open in PT, but i can't get these 3 synths to. is it possible? i do think they are cool, but i also have a bunch of synths that came with PT8, so if i can't use them, I guess I'm not out anything, they were freebies.

thanks everyone, i appreciate it.
