An older two voice K-S 'plucked string'. CPU runs high, some people like it.

MIDI note relates to the tonic but is transposed by a few semitones due to the marvels of science.

download Shoggoth










XChanter

This synger-derived 'algorithmic vocalist' uses a reduced phoneme set inspired by polynesian languages.

XChanter uses Lance Putnam's henon oscillator (orbit modeling) SEP. This is a very old VST, as of 2008 I still hear of it being used.

This is an old, very glitchy wavecycle-stretching formant shifter, suitable for FSU applications. This effect can be heard on the vocals of 'Planet Rock'.

download Smoky Joe


Spring

A 4-section waveguide with proprietary spring reverb algorithm. This VST has a denormal, I'll update it sometime.

download Spring





Waterverb

Uses massive cascades of allpass filters interspersed with short randomised delay times. An FDN is located in the feedback loop for 'ocean floor' echoes.

Depending on the input and feedback levels, the signal may drop silent due to DC offset. Highpass filtering is suggested.

download Waterverb










MIDI

Arp4midi

A wrapper for Chris Kerry's arpeggiator SEM. I have never used this plugin! Installation of MIDI plugins varies between hosts.

download Arp4midi












BloqSeq

BloqSeq switches between four 8-step sequences using an 8-step pattern. It has some application for performance, though the VST is proposed hypothetically until I figure out how I want to expand the pattern sequencing..

download BloqSeq




CC Cube

CC Cube gives you eight sets of MIDI cc values and transmits them at tempo. You may send the cc value sets manually, or configure an algorithmic progresson between them.

download CC Cube




Circuit

Circuit's algorithm is designed to create natural feeling rhythms by evening the distribution of beats and rests.

Each measure is divided into short phrases, and probabilities are assigned to each step so that a part can be weighted towards the downbeat or the upbeat.

Circuit can be used for live performance or run automatically.

download Circuit


Hypercube

HyperCube applies periodic parameter modulation to Circuit and Hyperion for algorithmic song structing. The grid of trimmers on the right indicates the probability for each band to progress to the next.

CC Cube is a generic version of HyperCube that sends 8 cc values.

download Hypercube


Hyperion

Hyperion MIDI VST has a semi-modular structure suitable for a wide variety of tuned algorithmic applications. LFOs and counters are used to easily create dynamic MIDI sequences and change them on the fly, or to modulate other components of the architecture.

Hyperion produces glissandos or subtly varying sequences for up to three parts on three separate MIDI channels using a simple chord function. It can also be used as a phrase arpeggiator to make sure that you never play out of key or out of sequence.

download Hyperion


Malt

Malt uses an LFO to periodically alternate between one or both of two midi channels for generating algorithmic sequences.

download Malt






Midilegato

Delays NoteOff events on one midi channel by up to 500ms to turn generated sequences into legato sequences.

download Midilegato



MiniSeries

A smaller, different version of Series. Miniseries has one modulated counter that progresses through eight MIDI note assignments.

Three LFOs and a variety of performance controls make MiniSeries capable of generating a wide array of sequences.

download MiniSeries


Period Seq

Period Seq generates rhythmic sequences using four counters.

download Period Seq





Phase Seq

For sequencing unquantised loops, host synced or not.

The position of each note is modulated individually by three LFOs, which can create effects like sequence stretching as well as randomisation.

download Phase Seq


Populus

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).

download Populus


Series

Series is a MIDI sequencer based on the concept of serialism.

Two separate counters can be assigned to three gate sequences and three modulation sequences. With three LFOs, four random step generators and performance controls, Series is capable of generating and modulating intricate arpeggios and rhythms.

download Series


Skunk

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.

download Strumee








Talent

An algorithmic MIDI application.

This plugin was replaced by Hyperion in 2008.

download Talent







Wav4midi

Plays wav files really slowly and translates them to MIDI cc values.

download Wav4midi










Models

Aerophone

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, however to appreciably render a human performance with this circuit requires knowledgable modulation of several parameters.

download Aerophone
listen to mp3


Boing2

Boing2 is my 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.

Bomb

This freeware synth uses a 6th order mass-spring and filtered noise for simple emulation of explosions. It is similar to Mass and Cymbal (the 'Mass-Springs' VST set) and Gun VST (Gun adds a multitrigger).

download Bomb


Cylinder33

A waveguide drum model as shown on gui.

Note that high feedback settings can exceed unity which can be employed for timbre or overload. Always use a limiter and low monitor levels when patching!

download Cylinder33


Friction

The friction algorithm is combined with a 2nd order mass-spring and two waveguide resonances for flexible emulative application.

Presets include squealing tires, squeaky hinges and axles, ww2 bombs, swingsets, et c.

download Friction





Gun

This VST is almost identical to Bomb VST (above) with the addition of a gently randomised clock for "automatic fire" effects.

Gun was exclusively available as a bonus item and is no longer available. There are better sounds for people to hear.

listen to MP3


KL Tract

The Kelly-Lochbaum model represents a cross-section of the vocal tract with reflection coefficients.

This implementation is a temporary offering for experimentation and does not include on-board modulators. Low settings for some reflection coefficients can produce feedback overload, so always use a limiter and low volume levels.

download KL Tract


Mass-Springs

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 create 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 emulative percussion synthesis, eg. 909 hihats.

download Mass-Springs






Phybes

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.

download Phybes







Piamo

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

download Piamo







Pling4

Pling4 is a plucked string model with improved sustain and high frequency response thanks to hermite interpolation. The timbre is also significantly improved with a more complex pick impulse for brighter, crisper plucked string patches.

Pling4 features 8 voice polyhony. More accurate emulation can be achieved by using one legato instance for each string. Just add your favourite resonance modeler and amp sim effects.

The full version of Pling4 is free. A donation or purchase is welcome if you enjoy it.

Snare

Cylinder33 with 4 'snare' vectors. This low number is closer to a gut snare eg. Tabor than modern snares, both may have similar damping dynamics.

download Snare






Stoq

This instrument is suited for synthesis of maracas and other shaker instruments and is inspired by descriptions of Perry Cook's work.

download Stoq





Surface

A 2d square resonance for percussion.

download Surface













Sym5

A 5-channel FDN that can produce sounds similar to 909 hihats.

download Sym5





Syng2

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.

The light edition (LE) removes the 'words' function for much faster songfile loading times when sequencing phonemes directly. Most of the music I've recorded in the last few years uses this instrument.

Nature

Fauna

Fauna produces natural and synthetic animal vocalizations using waveguide modeling techniques.

An extensive set of modulators make Fauna a versatile new generation synthesizer. Pitch and timbre can be controlled by traditional methods, or as a function of the form working as a whole.

The core of Fauna is a 5-segment KL tract coupled to a first order mass-spring. The movement of the 'glottis' interacts with reflected pressure waves, resulting in natural pitch cascades.

Fauna is ideal for animators and for musicians who wish to adventure into abstract territory. 107 patches.

Percussion

Brush

Brush is a quick wrapper for an impulse cluster generator. The density and length of the impulses can be changed to produce timbres similar to bitcrushing. The output is routed through a biquad filter coded by Chris Kerry to produce a simple and flexible midrange percussion module

November 2010: This VST has been recompiled to remove a lag in note velocity created by SynthEdit's internal velocity smoothing. Gate events now have 2.5ms of latency but reflect note velocity accurately.

download Brush


Clap of Luxury

A syncable noise algorithm is precisely amplified and applied to three filters to produce virtually any synthetic clap sound in existence.

The patch names were contributed by the users of kvraudio.com VST forum.

Synthesizers

Clearsynth

A simple 2-oscillator synthesizer for students.

The first 42 patches progress through the features. The patch names should acquaint the user with a basic knowledge of subtractive synthesis.

download Clearsynth


Expo

This 3-oscillator phase modulation VST includes emulations of my favourite classic Yamaha DX patches.

download Expo




Horizon

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.

download Horizon




Isnonu

A wrapper to audition Chris Kerry's Unison Osc and SV filter modules for SynthEdit.

Many tasteful patches have been contributed by Ouroboros and others to make Isnonu a useful low-CPU option for unison sounds and a perennial favourite.

download Isnonu


Noisemo

An unusual and noisy little synth - each wavecycle is produced by retriggering a noise generator, producing an arbitrary, harmonically rich timbre. Auto-crossfading is applied to the two oscillators to create smooth evolving textures similar to Ensoniq's Fizmo.

The ichneumon pictured on the GUI used to come in through the air conditioner and land on me for a ride to the front door when it wanted to go outside. Too cute.

download Noisemo


Perfecto2

Perfecto was inspired by my desire to reinstate the functionality of my missing Pro-One in a software monosynth by oversampling two oscillators that can modulate each other simultaneously.

The oscillators of the first edition were not antialiased, however pitch modulation could be locked to a user-set scale which could produce transposing, tempo-synced arpeggios. The second version used BLIT oscillators, which are antialiased.

While the second version still has up to 16x oversampling, cross-modulation is performed using the output of the BLIT table, which means that the output still differs from analog oscillators. The pitch scaling was removed and an assignable filter was added into the cross-modulation architecture. The functionality of the LFO was dramatically improved.

Perfecto2 is one of my most commonly used synths. The single envelope and LFO are limitations that indicate an upgrade is due at some point.

Regula

Basic VA architecture with a unique distortion effect produced by multiplying the decimal portion of the sample value.

Regula comes in two flavours: Regula can select between 67 alternative temperaments mapped to each octave, or Irregula, which is fixed to the pythagorean 17-tone scale used in arabic maqamat temperaments.

download Regula
download Irregula


Steam

Steam uses prepared wav files in a similar manner to some Waldorf and Ensoniq synthesizers.

I have been told that the header data for the wav files is written incorrectly (perhaps due to the free wav editor I used) which produces clicks during modulation. I would prefer not to offer this VST, for some reason it seems to be popular, five years after the fact.
