A family of FM sounds, all using 4 basic oscillators and various architectures, as used in the TX81Z synthesizer.
All these opcodes take 5 tables for initialization. The first 4 are the basic inputs and the last is the low frequency oscillator (LFO) used for vibrato. The last table should usually be a sine wave.
For the other opcodes the initial waves should be as in the table:
ifn1 ifn2 ifn3 ifn4
fmbell sinewave sinewave sinewave sinewave fmrhode sinewave sinewave sinewave fwavblnk fmwurlie sinewave sinewave sinewave fwavblnk fmmetal sinewave twopeaks twopeaks sinewave fmb3 sinewave sinewave sinewave sinewave fmpercfl sinewave sinewave sinewave sinewave
The sounds produced are then:
fmbell Tubular Bell fmrhode Fender Rhodes Electric Piano fmwurlie Wurlitzer Electric Piano fmmetal "Heavy Metal" fmb3 Hammond B3 organ fmpercfl Percussive Flute
kamp - Amplitude of note.
kfreq - Frequency of note played.
kc1, kc2 -- Controls for the synthesizer, as in the table:
