The most powerful loop software i have ever used is Acid Pro. It was designed from the ground up to handle loop based audio. What I used to do in it was to take a piece of audio set the looped region and hit start and it will loop over and over, then adjust the loop points until it is seamless. Then it has a feature called render and a sub setting of looped region only, that makes a reuseable looped audio clip.

Well worth the $69 to buy the Acid Studio version to have as a specialized tool in the arsenal.

This is cool if you need to add an instrument that you do not play very well. You can play a few bars and then find on bar that sound perfect and make a acidized loop out of it, then string that together to make a track.

A good example of this is if you want a particular strum pattern for an accoustic guitar, but to play the strum pattern over three or four chords flawlessly for a 4 minute song is difficult make a loop of each chord value, and piece them together in separate tracks and then render to one stereo guitar track. Import into any song.

For your need just loop the area to play along with for as many loops as you want.
