3.3.2. VCF 1
Now to shape the sound's timbre with VCF 1.
Sweep the Master Cutoff knob while playing. (VCF 1's Cutoff knob has the same effect when
you're only listening to one filter; the Master controls both together.)
With the initialized setting, the filter is set to lowpass, meaning it removes high frequencies.
Cutoff selects the corner frequency , which is where it starts operating. This has a radical
effect on the timbre of the sound.
Notice that there's no sound when you turn the way down (because you're blocking all the
frequencies from passing). You'd think the VCO, the sound waveform generator, would be
what turn the sound on and off - and it does - but sounds can also be controlled by opening
up a filter.
Bring up the Brute Factor knob, and experiment it, and with Drive. It's not necessary to point
out that you're adding some real testosterone to the sound. The Resonance control adds
more brightness. You can leave VCF 1 set where it sounds good.
The sound in its present state is just on/off, which is what you want for, say, organ sounds.
We'll adjust that next.
