Knifonium is an exceptionally beautiful-sounding analog synthesizer powered by a whopping 26 vacuum tubes. This high-end synthesizer features dual vacuum tube oscillators, a 4th-order ladder filter, a ring modulator, and a stunning steampunk design.
One of the rarest synthesizers currently in production
the original hardware units are handcrafted in small batches by high-end audio designer Jonte Knife, who has an unparalleled attention to detail. As beautiful as these synthesizers are, the Knifonium is more than just a stunning device capable of producing “strange sounds.” It is a uniquely musical and inspiring instrument with a wealth of sound-shaping and modulation capabilities. Fewer than two dozen were ever produced.
Even More Powerful Than the Original
The Knifonium plugin version is not only more accessible and easier to use than the original, but also boasts features unavailable in the analog world. This Knifonium plugin emulation adds 8 independent voices to the synthesizer, opening up new possibilities. Imagine an atmospheric pad sound created by a total of 208 vacuum tubes! It also includes mid-side and stereo widening functions, a unison mode for an even richer sound than the original, and a carefully curated BX effects section, including a vintage phaser system, SPL EQ Ranger, Waveshaper, and more, giving you a wide range of effects you’ll really want to use.
Tested and approved by Jonte Knife himself
Lead developer Jonte Knife has been creating vacuum tube-based hardware for mixing, mastering, and sound design for years, earning critical acclaim for both his tube and solid-state designs. His Knifonium has been meticulously crafted to be the best in its class. Brainworx engineers modeled the original hardware’s entire circuitry, including all 26 tubes, using proprietary tolerance modeling technology to recreate the natural variations in envelope parameters, pitch, LFO speed, and more, making this recreation as realistic as possible in terms of analog sound. Jonte confirms that the plugin sounds and performs identically to the original. In his words, “It’s unlike anything else.”
