Rigid Audio says the sounds are ideal for music production, movie scoring and video games.
Pad Therapy features nine sample-playback engines with 64 source waveforms each.
Each preset comes with three "states" (snapshots) that can be edited and played back in various orders and blended/morphed if wished.
It comes with effects like flanger, phaser and reverb as well as full randomization.
On top of that you can import your own WAV files into Pad Therapy via drag and drop.
