|
This class implements two simple FM Pairs
|
|
summed together, also referred to as algorithm
|
|
5 of the TX81Z.

|
|
|
\code
|
|
Algorithm 5 is : 4->3--\
|
|
+ --> Out
|
|
2->1--/
|
|
\endcode
|
|
|
|
Control Change Numbers:
|
|
- Modulator Index One = 2
|
|
- Crossfade of Outputs = 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.
|
|
|
|
by Perry R. Cook and Gary P. Scavone, 1995 - 2002.
