We are now in the download and voting stage of the KVR Developer Challenge 2012. This news item features an entry called Heliox by Remigio Coco. You can download it for free here.

Here's what they say about it:

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.
