Listen to Helix

They say a picture is worth a thousand words. In the case of Helix the picture is sound. Please listen to the audio demos of Helix's presets.

Hopefully you will be able to distinguish the quality of Helix through these sounds.


Why Helix?

The main oscillators of Helix allow you to pick from hundreds of included waveforms, or load your own. The waveform can be further bent and warped by two sets of controls, A and B. The in-between states are automatically created into something similar to a wave-table. The oscillator can then sweep across this sound-scape for unique and lively sounds.

Inspired by the "super-saw", Helix takes the unison-concept to the next level and allow you to make any waveform "super". This makes Helix capable of huge and wide unison pads and leads.

Great care has been taken to ensure no aliasing in the oscillators, so the sound is free from many artifacts traditionally associated with software (and Virtual Analog) synthesizers.

All parts of Helix are stereo in - stereo out. Oscillators, filters, shapers and effects. This enables a wider sound.

Three Filters per voice, including traditional low/band/high pass, EQ, and comb, less usual dynamics, to the exotic String Model and PM Delay, a delay where the delay-time is modulated in audio-rate.

Three stages of distortion / waveshaping per voice. Find your favourite style of dirt.

Both the Voice architecture and the Effects of Helix follow an approach where a signal can be mixed in or sent to the effect at any point. The result is unique freedom on how to apply filters and effects.


Computer Music

Issue 134 of Computer Music includes a great review that rates Helix 9/10. Some Nice quotes include:

"This is a synth of singular style and class"

"A superb synth, boasting in-depth programmability and a sound to rival any other, Helix has got us in a spin!"

Wilbert Roget, II

"The new version of Helix is a wonderful asset to my virtual instruments collection, and my go-to synth for nearly all my electronic needs. Its best feature is simply that it sounds good, has the smoothest tone and analog warmth of anything out there, along with tons of power in the distortion and some great high quality FX. Masterful presets by BigTone make it super fast to get started on designing sounds right away, and Helix's extensive parameters are now much easier to use with the new and improved UI. Along with the surprisingly low CPU cost, these features make Helix a perfect tool for both music producers as well as film and media composers."
