ableton

I mean, it's got some amount of pre-made samples and instruments... if I make a song using them, can I sell it? I think the license says I'm allowed to use the program commercially but I'd like to make sure...

Or can you just assign keys on the keyboard to what would be pads on an mpc?

when i render to disc the tracks are saved separately. like if i have 4 tracks. when i save it, it becomes 8 different different icons. 4 quicktime and 4 itunes. how do i save it so it only becomes 1 so i can convert and burn it on a cd.

i have a problem. when i go to the midi/sync tab in the preferences there is no button in the input column to turn on the remote setting! what do i do to get this thing working? (p.s. i run on windows XP)

what co,puter is best used for ableton and music production ? . . the laptop would be used for music and djing i know i can use macbook . . but wats best?
