Gong Amp takes an exciting experimental amplifier from the beginnings of electronic music to the plugin world of today. Available as AUv3 and Standalone. In 1932, Maurice Martenot was looking for a way to make his groundbreaking proto-synthesizer “Ondes” audible beyond what could be archived with the horns and loudspeakers of the time. He developed a set of “diffuseurs”, of which the “Métallique” was one. Instead of a paper cone or horn, Martenot put a gong behind the amplifier circuitry. This seemingly simple idea resulted in resonances and brilliant overtones that excite audiences to this day. Using a complex mixture of convolution processing, physical modeling, and feedback systems, we created an instrument that is true to the responsiveness of the original and even transcends it in terms of sound design possibilities.
Combustor
This audio effect extension transforms tracks with a unique time-bending resonator. Create vibrant textures, subtle resonances, and dynamic sweeps. It's designed for electronic musicians and producers seeking to add wild or organic qualities to their sounds.
- Time bending resonator effect
- Creates distorted textures and physical resonance
- Envelope follower for dynamic control
- MIDI input for melodic control
- Performative interface
- AUv3 compatible

*** 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.
