I use Rogue Amoeba’s Audio Hijack to quickly grab Max output when I’m messing around and suddenly want to preserve what I’m hearing. It’s super handy but generates a folder of recordings like this, whose origins I can’t remember at all. I have no idea what patch/setup I was using, whether I made or plundered the samples, or when, how and why I did it. A relic of an irretrievably forgotten creative process.
