Propellerhead Reason Refills

The Flatpack concept is to create fully tweak-able instruments and modular sound sources rather than sample patches. The Refill format, and especially the Combinator, make Reason one the best sound design environments. Each of our Reason Refills are large, varied compilations with patches for many of Reason's instruments.
