The saxophone is probably the most difficult instrument to emulate. Despite several attempts using different technologies, ranging from traditional sampling to sophisticated physical modeling, the results obtained so far fell short of the expectations. This is particularly true if real time playing is concerned. 

The Sax Brothers employ an entirely new technology, conceived by Stefano Lucato when it became clear that all the previously applied approaches simply could not do. The technical name is Synchronous Wave Triggering. It uses samples as a base material, chromatically performed by a professional sax players over a very wide dynamic range, and recorded with state-of-the-art technology. The resulting timbre is therefore that of the real instrument. But the analogy with a sample based library ends here. The underlying, proprietary technology allows continuous interpolation among different vectors like time, dynamics, pitch and formants. Advanced real time processing techniques yield realistic legato/portamento, vibrato, ornamentations & trills with phase continuity, constant-formant pitchbends, subharmonics, growl and flutter tongue to be performed in real time.
