xoxos has released Friction and Populus as freeware.
The commercial VST Friction won a poll at kvraudio.com and is now freeware. I’ve chosen to include Populus
Friction is a physical modeling synthesizer designed to be applicable to a range of emulative tasks, and is suitable for budget foley production or experimental music.
Populus generates MIDI sequences using an algorithm modeled on biological behaviour. The measure is treated as a ‘year’ and note events are determined by parameters describing the ‘life cycle’ of each note.

xoxos has released Acoustic, a freeware VST effect plug-in for Windows.
Acoustic is a simple acoustic body resonator model, consisting of a first order mass-spring for modeling the Helmholtz or ‘air’ frequency, and a banded waveguide.
Acoustic is a port of the body resonator model from the Boing2 bowed string synthesizer.
Visit xoxos for more information and a link to download Acoustic.
xoxos has released Boing2, a bowed string VST instrument for Windows PC.
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.
Boing2 is available for purchase for $25 USD. A demo version, limited to one voice of polyphony, can be downloaded here.

xoxos has released Stoq, a freeware stochastic impulse modeling VST instrument inspired by Perry Cook’s PhiSeM model.
xoxos Stoq – suited for synthesis of maracas and other shaker instruments
xoxos explains the model:
impulse is driven by ‘pitch’ which is a % for event per sample at oscillator pitch. tracking is implemented but architecture is geared towards percussion synthesis.
the event % is shaped with a ‘rise’ envelope that lowers the chance for events to immediately follow other events (ie. hysteresis, good for emulating ‘larger beans’). when rise is locked to pitch it can be shifted by +/- 2 octaves. ‘tail’ multiplies the % after the rise period to reduce longer gaps.
impulses are decay-stage enveloped and consist of either the envelope contour or enveloped noise, low pass filtered for dynamics performance, then routed to a bank for 5 bandpasses (# of bands can be reduced to save cpu).
Stoq is available as a freeware VST instrument for Windows PC. Download it here (1.35 MB).
xoxos has released Phybes, a physically modeled vibraphone VST instrument for Windows PC.
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.
Phybes is available for purchase for $15 USD.
A license includes a 6 voice and 13 voice version (for glissandos). A demo version is available for download here (limited to two voices of polyphony).

xoxos has released Malt, a freeware MIDI VST effect plug-in for Windows PC.
very simple – malt eats noteon messages on two channels. they’re gated by comparators running in opposite polarities from the same lfo.
if both thresholds were at halfway, the lfo would just alternate between the two parts, you can create a mid zone which passes both channels.
two uses.. either a simple call-response use for two generated sequences, or a 2 channel random note gate if you run the lfo at a fast rate.
Download Malt here.
xoxos has released Piamo, an elementarily modeled virtual piano, providing variable performance timbrality in a gentle emulation leant to abstraction.
“What would a simple physically modeled piano sound like?”
Piamo (“I love Pi”) provides the performance benefits of modeling in a low computational form.
The fundamental elements of the piano are modeled to create a timbrally expressive instrument less convincing than the excellent commercial emulations.
Piamo is available as a VST instrument for Windows PC. It is included with Pling3.
A functional demo is can be downloaded here (limited to three voices of polyphony, the full version is distributed with 8 voices).
