Two identical MIDI patterns, regardless of who created them, are going to lead to the same exact results when run through the same library. Since I am fully capable of making patterns from scratch, I may choose to build off of existing patterns as nothing more than a time saver. Plus, MIDI patterns still require plenty of creative prowess -- library integration, mixing, processing, etc. When it comes to audio loops, however, I do not know what sounds/synths/libraries were used to create them. To me, the choosing and mixing of the individual instruments, and the ability to edit them down to the single note level, is a fundamental aspect of music creation. So while my heart will not allow me to use audio loops, I can still be inspired by them no differently than I am inspired by listening to music in any form.
