User Manual
LFO 1 still won't modulate the pitch until you dial in a MOD Amount. Try + or -13, a fairly
radical pitch modulation, so you can hear the effect.
You'll also need to set LFO 1's Phase and Rate knobs where they're audible, so try 12 o'clock
as a starting point (as usual, after sweeping them to catch their actual voltage positions).
The pitch should oscillate up and down when you play.
Increase the MOD Amount to + or - 64, and it'll sound sci-fi. This is a good setting to
experiment with the Wave buttons to understand what they do.
MatrixBrute's LFOs have a choice of seven LFO waveforms, and you may be surprised to
see that they sound just like they look. Some of the same waveforms are available in the
VCOs, where they go by much faster, so this is a good way to get a handle on how they
sound.
Now the MOD Amount back to about 13, a vibrato effect.
The MatrixBrute's keys are pressure-sensitive. This is called Aftertouch, a controller source
when you push down the keys after the note has sounded. We're going to use Aftertouch to
increase LFO 1's rate a lot to bring in some reedy growl.
Aftertouch is next to the letter J, but LFO 1's rate isn't one of the 12 hardwired modulation
destinations. Columns 13 - 16 are user-assignable to pretty much any parameter on the
instrument.
