Heliox is a rather simple experimental synthesizer, with a "no-frills" GUI, capable of "weird" textures and noises, as well as "normal" synth sounds, like pads, leads and basses.

Main features are:

• monophonic, with 30 oscillators bank.
• adjustable oscillators' frequencies, ranging from single frequency to harmonic and non-harmonic series.
• oscillators can be purely sinusoidal, or "shaped" by an adjustable parameter.
• adjustable attenuation factor between successive oscillators.
• 30 LFOs, each modulating amplitude of corresponding oscillator.
• adjustable LFOs' frequencies, similarly to oscillators.
• LFOs can be purely sinusoidal ("bell-like") or "shaped" by 2 adjustable parameters: center and sharpness.
• phase shift between successive LFOs is adjustable.
• LFOs can be periodic or randomly intermittent, with adjustable "density".
• ADSR envelope.
