RAST-A classic synth for HALion

Voltage-controlled synthesizer

RAST-A for HALion is an homage to the legendary voltage-controlled synthesizers of the 1980s. It not only models the musical influence of individual hardware components on the sound, but also simulates the temperature drift of VCOs. Combined with a classic modeled filter, you get all the tools to bring back the vibrant sound that we all loved so much.

Recreated analog synth technology

This modeled synthesizer is heavily inspired by a classic synthesizer which was famous in the ’80s. The original was used by artists like Prince, Queen, Styx, Van Halen and Supertramp. However, RAST-A is not intended to be a one-to-one clone, but rather an homage to a specific sound which dominated an entire decade of music.
