Four Engines and the X/Y Performance Pad
Aura's four sound engines are blended through a central X/Y pad. Moving the pad changes the balance between engines, so a patch can continue to shift while you play it. Vir2 Instruments says you can record the pad movement to automate it, and you can control the pad with a mouse or an external MIDI controller.
This makes Aura suited to live scoring of evolving textures, where the motion of the sound is part of the performance rather than a fixed loop.
