ULSE
The pulse wave contains only odd numbered harmonics (3, 5, 7 etc.)at 50% pulse width (square
wave). This waveform is special in that its harmonic content can be varied continuously, by adjusting
the pulse width (PWM).

The pulse wave at 5% pulse width.
The T knob controls the pulse width of the pulse wave, from 50% (square wave) to 99%. You

ULSE IXED TIME
A normal pulse wave has a pulse width adjusted relative to the wavelength, usually in % (see above).
The Pulse Fixed Time algorithm instead generates a pulse wave where the pulse width is adjusted in
absolute time values (with the T
results in a spectrum with fixed formants, similar to the character of many acoustic instruments.
The waveform in itself is not different from the normal Pulse algorithm, but it behaves differently
over the keyboard range.
