Playing and Editing VL Voices The Instrument The key block in this algorithm is the instrument, since it is here that the fundamental tone or "timbre" of the sound is defined. The instrument model consists primarily of a driver - the reed/mouthpiece, lip/mouthpiece, or bow/string system - and a resonant system corresponding to the tube and air column or string. In all these instruments pressure applied here (the driving point) causes vibration which results in sound. Reed vibration Lip vibration Air vibration String vibration One of the remarkable features of the Virtual Acoustic Synthesis system is that just about any driver can be used with any type of pipe or string. Drivers Pipes/String NOTES • The sound thus produced is amplified and sustained by the body of the instru- ment. • The pitch of the sound is determined by the length of the air column or string, and the timbre is a complex product of the driving source (reed, lip, air, string), the shape of the resonant cavity, the materials from which the instrument is made, etc. 64 Guided Tour
