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 a whole decade of music.

As colorful as the ’80s

You can easily switch the design of RAST-A with just one click. Choose between red, black, green or blue.

Open the panel for something new

Open the panel and you open up a new world of sound-shaping options. Each of the voices can be tuned differently and even the arpeggiator is designed to bring back pure simplicity of operation.

Born to be alive: The hardware components

Individual components of a hardware synthesizer always have an influence on the sound. RAST-A simulates these to make it sound very real.

A real classic: Polyphonic portamento

Each voice comes with separate portamento. It lets you recreate the typical outstanding glides which some synths were famous for.
