INTEGRA-7 Sound Editor - Download -

The above link leads to an I-7 editor (Windows & OSX) that is free of charge and works independently from an DAW.

I learned of this from the Roland clan forums here:
Roland Clan Forums • View forum - Integra 7

In my case this program has worked quite well for editing Super Natural Acoustic, Synth, Drums as well as PCM Synth & Drums as well as Studio Set building and editing.
