/*! \class PercFlut
|
|
\brief STK percussive flute FM synthesis instrument.
|
|
|
|
This class implements algorithm 4 of the TX81Z.
|
|
|
|
\code
|
|
Algorithm 4 is : 4->3--\
|
|
2-- + -->1-->Out
|
|
\endcode
|
|
|
|
Control Change Numbers:
|
|
- Total Modulator Index = 2
|
|
- Modulator Crossfade = 4
|
|
- LFO Speed = 11
|
|
- LFO Depth = 1
|
|
- ADSR 2 & 4 Target = 128

The basic Chowning/Stanford FM patent expired
|
|
in 1995, but there exist follow-on patents,
|
|
mostly assigned to Yamaha. If you are of the
|
|
type who should worry about this (making
|
|
money) worry away.
