Just to remind you, this app was originally a DS home brew application called DS repeater. It’s one of only a few that have made the jump from DS to iOS, which is a shame. Still, here it is, and here’s what it has to say about itself:
iterator is an inspiring sample based musical instrument with a stylistic interface. The premise is simple: The x-axis controls the sample playback position. The y-axis controls the repeat speed. The result is surprisingly musical.
Create your own soundscapes using any of the built-in 75+ samples from over 25 artists, including Richard Devine, Parallel Worlds, Toppobrillo, Atomic Shadow, and many more. Or, supply your own .mp3s through iTunes.
The app is priced at $3.99.
