Yamaha VL70-m User Manual

If you’ve read the “Virtual Acoustic Synthesis” section (if you haven’t, please
do so — page 6) you should understand the concept of “controllers” as applied
to the VL70-m. The “controller parameters” correspond to simulated character-
istics of the instrument model — e.g. breath pressure, embouchure or tonguing.
Any of these can be controlled by you via “physical controllers” — e.g. a breath
controller or modulation wheel — assigned to the required controller parameter.

The effectiveness of the VL70-m as a musical instrument depends to a great
deal on how well you learn to use these controllers. Since the VL70-m sound is
produced by a computer-based physical model rather than a oscillator-based
tone generator, there are no hard-and-fast rules as to how any controller will
actually affect the sound. There are guidelines, based on the rule of the corre-
sponding controller parameter within the physical model, but proficiency with
the VL70-m depends more on experience and practice — just as it does in any
acoustic instrument.

"Physical controllers" such as
the Breath or Foot Controller
can be assigned to "controller
parameters" such as Pressure
or Embouchure.
