Yamaha VL1-m Virtual Acoustic Tone Generator.

Extended information

Instrument controls:
• Pressure (or bow speed)
• Embouchure (tightness of lips or bow pressure on the string)
• Pitch (the length of the tube or string)
• Vibrato (affects Pitch or Embouchure via an LFO)
• Tonguing (simulates half-tonguing damping of saxophone reed)
• Amplitude (controls volume without changing the timbre)
• Scream (drives the whole instrument into chaotic oscillation)
• Breath Noise (adds widely variable breath sound)
• Growl (affects Pressure via an LFO)
• Throat Formant (simulates the player's lungs, throat and mouth)
• Dynamic Filter (controls the cutoff frequency of the Modifier Filter)
• Harmonic Enhancer (changes the harmonic structure of the sound)
• Damping (simulates air friction in the tube or on the string)
• Absorption (simulates high frequency loss at the end of the tube or string)
