Ratings and reviews

This app is essential for any ambient/noise musician. I've been using the pro version for over 1 year and it has allowed me to make some serious tracks while travelling/not in the studio. It can turn anything into an endlessly evolving ethereal dream or your worst nightmare. EDIT: The new update has heavily limited the types of audio files you can import, putting a wrench in the workflow/capabilities. I reached out to them about and am awaiting response.

I LOVE IT! What sort of sick, twisted mind does this? ... Makes this?... Listens to this? It's so freakishly cool! If you've got a lifetime to waste tweaking virtual knobs and reshaping samples, you will absolutely love this, and never find all the of the possibilities. Gorgeously twisted sonic experimentation with loads of weird science for your darkest moments. If you tweak audio, try this.

I'm a techno freak and let me tell you this little app is fun. You might not wanna play with it with a loud speaker alone at night because you can get some scary sounds out of this thing once you figure out what you're doing, play with it for an hour or 2 and you'll be surprised what's coming out of it. I always wanted a granular synthesizer and now I know why... this thing is really dope and fresh. Try getting some monk chants going on 1 channel and some chords playing on another.
