Look at this beautiful iPad granular sampler called Borderlands from Chris Carlson. I can see many of these futuristic interface elements influencing other pro-audio app developers. We live in a great time being able to touch our sounds like this. I can’t wait for this to be released.
“The audio files can be moved and resized using typical single and double finger gestures. Currently the orientation of each rectangle may be toggled by touching the object with a third finger. A grain cloud can be created by double tapping anywhere on the interface. This immediately opens the cloud for editing, exposing a number of parameter regions around the cloud. Each region can be dragged or thrown between a hard coded min and max value. Users may edit the number of voices in the cloud, duration of each voice, overlap of the voices, playback rate or “pitch” of the voices, and the frequency of an LFO controlling the pitch of each voice. This view may be hidden by double tapping on the grain cloud again. Several discrete parameters are available as buttons at the bottom of the interface. These include the grain direction (random/forward/backward), the window type (hanning, exponential decay, exponential growth, sinc), and the stereo distribution of the grains (two modes – unity preserves the original spatialization of the audio file, stereo pans grain voices left and right sequentially.” – Chris Carlson
