The Sounds of Nature VST collection includes emulations of wind, rain, thunder and insect noises, and a waveguide model of the songbird, or oscine vocal tract.

These VSTi were voted first place in the kvraudio Developer Challenge 2007, a contest intended to promote development of freeware.

Aerophone models lip valve instruments with cylindrical bores such as trumpets and trombones. The lip valve is modeled with an oversampled 3rd order mass-spring to emulate expressive acoustic performance.

The elementary acoustic circuit is capable of producing impressive emulations. Please be aware that to appreciably render a human performance with this circuit requires a volume of knowledge and application.

Aerophone is $25, the demo edition plays a random MIDI note at intervals.

Boing is a bowed string model. Oscillation is produced with a friction calculation applied to a dispersive waveguide string with oversampling rates of up to 16x. The string loop includes a mass-spring modeled bridge. The body resonator consists of a mass-spring "air tone" model and a 5 band banded waveguide.

The demo is limited to one voice of polyphony, the $25 licensed edition has 4 voices (or more by request).

Phybes is a banded waveguide suited for vibraphone and other mallet instrument emulations. The mallet impulse is modeled with a mass-spring to produce tonal variation from dynamic performance.

The demo is limited to two voices of polyphony, the $15 license includes a 6 voice and 13 voice version (for glissandos).

Piamo is an elementarily modeled virtual piano, providing variable performance timbrality in a gentle emulation leant to abstraction.

Piamo is included with Pling3, the functional demo is limited to three voices of polyphony, the full version is distributed with 8 voices.

Pling3 is an all-purpose plucked string model suitable for synthesis and emulations.

Pling3 is improved by coupling vertical and horizontal waveguides and by tuning the pitch response of the stiffness filter.

A second version, Pling3b is included with an oversampled string.

Pling3 is $20, the functional demo is limited to two voices of polyphony.

Skunk is a four part algorithmic percussion sequencer. Probability is used to determine which of eight sequences follows the current selection. This concatenative effect is useful for cross-rhythms and other simple rhythmic automations.

The demo is limited to host bpm settings that are multiples of 40. The price of purchase is $12.

Horizon combines lush stereo unison voicing with a phrase sequencer that stays in key when the sequence is transposed.

This simple format makes Horizon ideal for lead sounds in dance and other styles. The oscillators are also suitable for producing panoramic pads, before any stereo effects are applied to the signal.

Horizon is priced at $25. The demo is limited to two voice polyphony.

Syng2 is a voice synthesizer which uses four bandpass filters to produce formants in any spectrally rich signal, or using an internal oscillator. The phoneme can be selected on a second MIDI channel, or preset words can be triggered.

Syng2 was designed as an intelligible, low-cpu voice engine for Breathcube 2. The articulation is intended to be more natural than other 'robot voices' using this method, with plosives slightly emphasised to be heard with music.

Populus generates MIDI sequences with a 'biologically modeled behavioural' algorithm. The measure is treated like a 'year,' wherein notes grow, reproduce and combat.

This VST is now freeware (june 09).

This emulative VST uses mass-springs and a noise source. It is almost identical to the freeware Bomb VST, with the addition of a gently randomised multitrigger clock for "automatic fire" sounds.

This instrument is included with all other licenses.

Friction VSTi combines a 2nd order mass-spring with a friction algorithm and two waveguide resonances. It is capable of elementary emulations of sounds produced by tangent surfaces, such as squeaky hinges and squealing tires.

This instrument is proposed for experimental music and foley sfx.

Friction was elected as freeware at kvraudio.com june 2009.

Mass VSTi and Cymbal VSTi are percussion synthesizers that use mass-spring models to produce realistic dynamic and timbral effects.

Boundary conditions imposed upon the movement of a multi-order mass-spring provide complex timbres that evoke common modes of vibration in acoustic forms.

These models are augmented with conventional subtractive elements to comprise low-cpu solutions for improved realtime percussion synthesis.

These VST are priced at $15 for the pair. The demo versions remove some parameters.

Waiting for an update to Talent? Hyperion is a flexible algorithmic MIDI VST designed primarily for melodic parts and capable of outputting three notes on three separate MIDI channels.

Hyperion's flexible architecture and low CPU can be applied to live performance or to algorithmic composition. The "Unidentified Flying Object" of the VST world.

Hyperion is $25. The demo is limited to bpm settings that are multiples of 40.

Fauna is a vocal tract model capable of emulating many animal (and human) sounds.

The design is intended to produce natural sounding calls. Oscillators can also track the keyboard and create an array of unique synthetic textures.

A fully patched version of Fauna is available for $25.

Circuit is a probability based MIDI sequencer that joins short phrases together to create natural feeling rhythms.

The concept is derived from classical schools of drumming, such as Tal notation for Tabla.

Circuit is priced at $25. The demo is limited to 80bpm.

Inspired by Serialist composition, Series and MiniSeries are performance sequencers which use a modulated counter to index steps.

Combined with Circuit's multitriggering, both versions create dense mathematic sequences with a few settings.

Intended for percussion and experimentation, Series is also a powerful arpeggiator.

Series is included with other purchases or may be purchased individually for $20.
