The Reason version includes 166 NNXT presets, 50 Combinators, and is 600 Megabytes (compressed). While The Resonant Drop does contain some pretty and shimmering deep space ambiances, it is mostly intended for that more disconcerting, cyberpunk, perhaps even downright scary future-vision.
Also available for Native Instruments' Kontakt (requires version 5 or higher).
Price: $59.95. Now available for Reason version 6 or higher.
