Exemple files of music made with loops.
The "4barmix" pieces were "composed" by adding 4-bar loops that came with the software, DoReMix, a bundle sold with the soundcard Soundcanvas from Roland, around 1995.
I will upload a couple of things I have done when I have tested GarageBand - where I have used both Apple Loops, played midi sounds on the computer keyboard and in some cases added live recordings. The first example is "A Different Code". The second is "Exdream" - a remix of an old midi recording, an improvisation with church organ and taiko drums, and other sounds, now with Apple Loops added.
