Detailed Description

STK singing FM synthesis instrument.

This class implements 3 carriers and a common modulator, also referred to as algorithm 6 of the TX81Z.

    Algorithm 6 is :
                        /->1 -\
                     4-|-->2 - +-> Out
                        \->3 -/

Control Change Numbers:

• Vowel = 2
• Spectral Tilt = 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.
