lpzpulse, pkzpulse, bpzpulse, hpzpulse: resonant filter sweeps on a trapezoidal wave.
This waveform family simulates the sound of a trapezoidal pulse wave processed by a low-
pass, peaking, band-pass, or high-pass resonant filter. The parameter controls the cutoff
frequency of the filter. pkzpulse is particularly good at recreating the dirty, saturated
sound, of a sawtooth filtered by the least academic of the 2-pole analog filters.
ztriangle: mystery...
This waveform vaguely evokes two hardsync'ed oscillators — the parameter controlling
their frequency ratio. It may or may not have been used in the Casio CZ-101.
pad: swarm of 4 buzzing detuned sawtooth waves
As the name implies, this waveform made of four stacked sawtooth waves is useful for
pads (when a copious amount of filtering is applied) or for buzzing trance leads. The
parameter controls the amount of detuning between the four waves. Note that no
bandlimiting is happening here, so this thing doesn't sound quite good above C5... but it's
doing a perfect job in the bass range!
