Waveform Harmonic Content - Yamaha TX81Z Product Manual

WAVEFORM HARMONIC CONTENT

In addition to sinewaves (pure tones), the TX81Z operators can use 7 more complex waveforms, These wave-
forms are not modeled after any "real" instrument, but are mathematical transformations of sinewaves.
Here is the harmonic content of each waveform. The amplitude (volume) of each harmonic partial is given as a
percentage of the fundamental.
W1
Sine wave. Only fundamental.
W3
Even partials.
W5
Partials 2, 3, 5, 7, 9 . . . . (stronger partials than W4)
Second partial is stronger than fundamental.
W7
Partials 3, 4, 5, 7, 8, 9, . . . (no 2, 6, 10, . . .)
W2
Odd partials somewhat like a square wave
W4
Partials 2, 3, 5, 7, . . . . . . .
W6
Partials 2, 3, 5, 6, 7, 9, 10, 11, . . . (no 4, 8, . . . .)
Second partial is stronger than fundamental.
W8
Partials 3, 4, 5, 7, 8, 11, . . . . (no 2, 6, 8, 10 . . . .)
