Percussa has introduced LoopShaper, a free sound design tool designed to be used with the AudioCubes. It lets you use AudioCubes with your existing VST instruments to create sounds and loops.
LoopShaper is a standalone application, hosts your VST instruments and lets you interact with them in a hands-on fashion using AudioCubes. The software will loop, let you record your interactions and play over them continuously. By using two AudioCubes, you can control four parameters of the sound at once.
