sounds bright as well, but with a hollow, clarinet-like char-
acter. The next two sliders do also give you square waves,
but their pitch is one or two octaves lower, respectively,
than the pitch of the other waves. Use them to give your
sounds a really huge, wide character and the deepest
basses. Or try this for unusual bright timbres: set the oc-
tave switch to 4 feet, pull down the sliders of all waves but
the square wave two octaves below the original pitch. Now
carefully pull up the sawtooth slider and note how bright
your square wave gets…
The remaining slider is for the noise waveform. This
sounds exactly as it reads: noisy. It is non-pitched, mean-
ing it has no audible pitch and is thus independent from
the note you play or from the setting of the octave
switches. When used alone, this is the waveform of choice
for all kinds of non-pitched percussion instruments, ex-
plosions, and sound effects like wind or waves. If you mix
it to the other waves, you can emulate things like breath
noise in a flute, or, when added at a very, very low volume,
it can give your sound that animated high-end sparkle.
That’s almost all about the oscillator of the Percusor, so
let’s move on to the filter. It features the main controls al-
ready familiar to you from the introduction: Cutoff for
darkening the sound, Resonance for sharpening it. You
will find them in the middle of the Percusor’s surface.
Please try these controls intensively, as they are, together
with the almost endless mix combinations of the wave-
form sliders, the most effective and thus important tools
for your sound creations.
In between the filter controls and the six waveform sliders
you will find the Vib/Wah control. Turn it to the left. You
will hear the pitch of the sound going up and down and up
and down and so on. This cyclic pitch change is called a
“vibrato”, thus the abreviation in Vib/Wah. The vibrato in-
tensity is set with the left range of Vib/Wah. The vibrato
speed is set with the Speed control below Vib/PWM.
Now turn Vib/Wah to the right: You will not hear a vibrato,
but a cyclic change in the sound color itself, as if you
moved the Cutoff control manually up and down and up
and down and so on. And this is exactly what is happen-
ing, but it is now done automatically for you by the Percu-
sor. The speed of this so-called “Cutoff modulation” is
controlled with the Speed control below Vib/Wah. If you
do not want to hear neither vibrato nor cutoff modulation,
just click the little “zero” symbol above the Vib/Wah con-
trol.
