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.
