xoxos has released Aerophone, a virtual synthesizer instrument for Windows PC.
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 available as a VST instrument plug-in for Windows PC for $25 USD. A demo version is available for download here (plays a random MIDI note at intervals).
Visit xoxos for more information and a demo mp3.
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.
Visit xoxos for more information and links to download Friction and Populus.
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).
