Knif Audio Knifonium

Capture the tone of a boutique synthesizer powered by 26 vacuum tubes
The Knifonium is an exceptionally beautiful-sounding analog synthesizer that is driven by a whopping 26 vacuum tubes. This upscale synth features two tube-driven oscillators, a 4th order ladder filter, a ring modulator, and a gorgeous “steampunk” aesthetic.

One of the most rare synths in production today
The original hardware units are handcrafted in small batches by high-end audio device designer Jonte Knif, with his incomparable sense for detail. As beautiful as these synthesizers are, the Knifonium is much more than a stunning piece of eye-candy capable of making “weird noises". It is an exceptionally musical and inspiring instrument with so many possibilities for shaping and modulating sound. Fewer than two dozen of them have ever been made.

Even more powerful than the original
Not only is the plugin version of the Knifonium more accessible and easy to use than the original, it also includes features that aren’t possible in the analog world. This plugin emulation of the Knifonium adds 8 independent voices to the synthesizer, opening up a new universe of possibilities. Imagine an atmospheric pad sound produced by a total of 208 vacuum tubes! It also includes mid-side and stereo spreading capabilities, a unison mode for even richer sounds than the original, and a carefully-curated BX effects section, including a vintage-style phaser, SPL EQ Ranger, Waveshaper, and more, giving you a wide range of effects that you will actually want to use.

Tested and approved by Jonte Knif himself
Lead designer Jonte Knife has been making vacuum tube-based hardware for mixing, mastering, and sound design for years, gaining critical acclaim for his tube and solid state designs alike. His Knifonium was carefully crafted to be the best in its class. Brainworx engineers modeled the complete circuits of the original hardware, including all 26 tubes, applying their patented Tolerance Modeling Technology to recreate the natural variations in envelope parameters, pitch, LFO speed, and more to make this recreation sound as realistically analog as possible. Jonte confirms that the plugin sounds and behaves just like the real thing. In his words "It sounds like nothing else".

  What I love about the plugin version is the added polyphony feature. This really opened up another world for me.

  Knifonium is going to be huge for film scores - the gnarly nature of this synth will be able to power through any mix and deliver a huge amount of weight to anything it's unleashed on.

  Fat analog sound but it's all about that feedback knob.

  Knifonium really is a Swiss Army knife of a synth. Nothing really sounds like it. As I’m always striving to make the most unique sounds ever, I feel like Knifonium is amazing at doing that. The… Read More

  Super fun synth to work with. There is something very magical to the built-in saturation features and the GUI is really inspiring to me. I go to Knifonium for grit analog-sounding basslines.

  This has to be one of the smoothest sounding, yet warmest synths I have ever heard. The sound it projects is beautiful. Super clarity with nothing harsh about the sound whatsoever. The more I mess… Read More
