Vcf 1 - Arturia MatrixBrute User Manual

Now that you're hearing VCO 1 on its own, move the Coarse knob to hear what it
sounds like at different pitches.
There are four different waveforms in this VCO - a Sub oscillator that sounds
an octave below the other three. Each wave generator has a level knob on the
bottom row and an enhancer for it on the top.
Turn all four down, then bring each one in one at a time so you can hear the
different waveforms. Try the enhancers to hear their effects on the waveforms.
For now, leave everything at 12 o'clock. It doesn't matter that this isn't a great
sound.

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.
