Homegrown Sounds has announced the release of its new Astralis Bion synthesizer VST instrument plug-in for Windows and announced the Astralis Synth Collection Group Buy.

Astralis Bion is the most powerful synth in the Astralis range. It has a custom built oscillator with 3500+ possible waveforms and many filter types including Low Passes, Hi Passes, Band Shelf and Comb. The Astralis range of synths are primarily designed for easily creating atmospheric and ambient landscapes, though Bion is useful for any style of music due to the huge array of features.

Astralis Bion consists of two identical synths each with its own envelopes and filter, etc. There are many features including an extensive effects section, Microtuner, Programmable Arpeggiator, Gapper, two Modulation Sequencers, Gate Sequencer, LFO and a flexible Modulation Matrix. Whilst the possibilities of Bion are deep, a sophisticated randomization system has been designed so that creating new sounds on the fly is easy. There are also local randomizers on every section so that you can just randomize a synth section of just an oscillator, for example.

Each synth has a dual oscillator so that 2 waveforms can be selected and then one of 21 different modes can be used to decide how they interact. The are numerous modes including Add, Subtract, Split and FM. As for the wave shapes, there are a number of presets such as Sine, Triangle, Saw, Square, etc. as well as the Wavesets, which are a collection of pre-defined shapes selectable from the Waveset slider. The random button can be used to quickly pass through sounds until a suitable one is found.

The FX Section includes Stereo Delay, Flanger/Filter, Ring Modulator, SoundScaper and Organic, as well as a compressor. There are 127 possible routing combinations which brings a huge world of possibilities for atmospheric sounds. SoundScaper is a delay based effect which is capable of effects such as combs, Reverbs, Echoes and complex undulating delay beds.

There is also a Recorder built in which automatically captures the Synth output to WAV at either 16, 24 or 32 bit. The Microtuner can load Scala files and the synth comes with 300 Patches included, which are shared across all of the Astralis Synths.
