Detailed Description

STK Wurlitzer electric piano FM synthesis instrument.

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

    Algorithm 5 is :  4->3--\
                             + --> Out
                      2->1--/

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.
