/*! \class Moog
|
|
\brief STK moog-like swept filter sampling synthesis class.
|
|
|
|
This instrument uses one attack wave, one
|
|
looped wave, and an ADSR envelope (inherited
|
|
from the Sampler class) and adds two sweepable
|
|
formant (FormSwep) filters.
|
|
|
|
Control Change Numbers:
|
|
- Filter Q = 2
|
|
- Filter Sweep Rate = 4
|
|
- Vibrato Frequency = 11
|
|
- Vibrato Gain = 1
|
|
- Gain = 128
