The Instrument - Yamaha VL70-m Owner's Manual

NOTES
• The sound thus
produced is amplified
and sustained by the
body of the instrument.
• 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.

Virtual Acoustic Synthesis
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.

One of the remarkable features of the VL70-m's Virtual Acoustic Synthesis
system is that just about any driver can be used with any type of pipe or string.

The Instrument

In all these instruments pressure applied
here (the driving point) causes vibration
which results in sound.
