*** Note: Combustor is an Audio Unit effect extension and requires an AUv3 compatible host app, like Logic Pro, Drambo or GarageBand. It does not run as a standalone app *** Combustor is a unique, wild resonating body fashioned to spice up or extremely transform your tracks. At the heart of Combustor is a custom time bending resonator that doesn't sound like anything you have heard before. You can create anything from vibrant, distorted texture, perfectly suited for "hardcore" electronic musicians, to subtle physical resonance, which is often lacking in synthesized sounds. Combustor contains an envelope follower, to create dynamic-controlled pitch or filter sweeps. It also has MIDI input, that controls resonator's pitch, to make something melodic and organic out of non-melodic sounds, like drums. With just a few knob turns, a boring sound can be turned into screaming madness that sounds like it went out of control. A simple and straightforward interface makes Combustor a performative tool that allows you to directly interact with your sound.

Read full description

Unleash sumptuously smooth saturations, disgracefully dirty distortions, and maximally mad mashups! BLEASS has designed Fusion to be one of the – if not the – most versatile and adaptable distortion and saturation plugins available today, able to completely change its entire tone and character in an instant. The magic comes from the way in which wavetables define the sonic results of processing, and so empower the plugin with the versatility to satisfy your every sonically-destructive whim. Whether you want to spice-up your audio with the lightest sprinkle of sizzle, smother it in a luxuriant fluffy blanket, or shatter it into fractured shards, BLEASS Fusion provides the perfect waveshaping weaponry for the job. And should you find that the 58 included wavetables don’t quite fulfill your distortion dreams, importing your own custom wavetables is simply a matter of dropping a file into a folder. A pair of multi-mode resonant filters allow BLEASS Fusion to focus its fury on particular frequencies, or can be used to tame its more extreme excesses. And with a full complement of modulators that add movement and dynamism to your sound, a huge palette of expressive, rhythmic and evolving distortions are just waiting to be explored. BLEASS Fusion is also available for desktop More information on www.bleass.com/fusion
