Here’s another new iPad music app with a wicked interface. This one is called FEED (iTunes link). It’s a sampler/looper. The waveform is circular. You can loop any parts of it. The circle size controls volume. You can scrub and more. $1.99 USD.
“Feed enables complex, rich manipulation of a “live feed” of sound. Record, playback, loop, pitchshift and modulate the live feed in a variety of ways to spontaneously create compositions from musical sources, spoken word or ambient sound.” – theincidental.com
