WaveShaper is a new iPad app that lets you scrub samples. You can load your own and morph between sample locations. The description sounds a lot like the NI’s Skanner however the results are far less musical, more glitch. I really like using my own samples in iOS apps but connected to iTunes to transfer samples in isn’t elegant. $5.99 in the App Store.
“WaveShaper is an audio synthesis app that lets you control a unique sound generating algorithm using a large XY controller. Use two fingers to control four parameters in real-time. This app is full of surprises and will create sounds unlike any you might create in a typical sound design plugin!” – waveshaperapp.com
