Lfo/Aftertouch/Matrix - Arturia MatrixBrute User Manual

• Notice how every note plays at the same volume, no matter how
hard you play the keyboard? The Velo/VCA fader lets you dial in
how responsive the envelope is to keyboard velocity , which is what
electronic keyboards use to determine how hard you intended to play.
When the slider is all the way down, every note plays at full volume; all the way
up, and you have to slam the keyboard to get it to speak up. See whether you
like three quarters of the way up.
The MatrixBrute has two other Envelopes. ENV 1 is hardwired to the two filters'
Cutoffs. It works the same way, so you can experiment with its effect.

3.3.4. LFO/Aftertouch/Matrix

Next, how to route modulation sources in the Matrix, including the LFOs.
Low Frequency Oscillators (LFOs) are periodic waveforms just like VCOs, only
they're very low - which by definition means they're very slow. Rather than being
used as sound sources, LFOs 1 & 2 are used as modifiers to add movement
to other parameters. (However, VCO3 is intended to be used as both a sound
source and a modifier.)
Press the MOD button. The Matrix becomes an electronic patchbay.
We're going to route LFO 1 to VCO1's pitch. Depending on the settings, this can
create anything from a vibrato effect, to subtle movement, to some really crazy
stuff.
Like all modifiers (other than the hardwired envelopes), LFO 1 has to be routed
before it does anything. Modulation sources are on the rows on the left of the
Matrix, destinations are columns across the top.
