| An abbreviation for Virtual Acoustic Lead — This engine is based on technology developed by Yamaha with CCRMA (Center for Computer Research in Music and Acoustics, Stanford University). The first application of Physical Modeling of acoustic instruments, the VL is a Virtual Acoustic Self-oscillating (VA/S) model. It models the kind of instrument where the player is responsible for applying 'pressure' to the instruments driver (mouthpiece or bow) in order to cause the oscillation. In addition to the mathematics occuring in the driver the technology also models the pipe or string (response chamber) and the virtual player's physical input. The hyper-realistic sound of VL is due to the accurate 'behavior' of the model under similar physical conditions. There are no samples in this technology. All sound is generated via the calculations in real-time. |
