The Gerudo Messiah (Zelda + Castlevania Mashup) | SWAM Virtual Instruments
I took the Gerudo Valley theme from Zelda: Ocarina of Time and combined it with the New Messiah theme from Castlevania II: Belmont's Revenge in a string, horn and flute arrangement created entirely using Audio Modeling's fantastic SWAM Virtual Instruments.
These amazing plugins use physical modeling to emulate acoustic instruments without using any samples. Keep watching after the arrangement for a look into the software.
