2.4. Custom LFO waveforms



This section refers to section 4.11.2 "Draw an LFO waveform" (p.28) in the MatrixBrute 2.0 manual

Press both Wave Selection arrows at the same time to enter LFO Draw mode. All of the LFO

waveform LEDs blink three times, and the Preset screen shows "LF1" or "LF2" depending on

which LFO is being edited. The Sequencer display says "EDIT".

The matrix buttons reveal the custom LFO waveform. They are also used to define the

waveform. Here's how it works.

• Columns 1-16 are the steps in the waveform
• Row H is the zero-crossing point
• Rows A-G are positive values
• Rows I-O are negative values
• Row P decides if the change between the previous and current steps is instant or

smoothed

• If a step in Row P is blue the transition is instant. If it is red the transition is

smoothed.

For a simple example:

1. Start with an initialized patch (Hold Panel, press Preset)

2. Set up a mod route of LFO1 > Pitch (press MOD, then E1, and set an amount with

the knob above the matrix)

3. Enter Draw mode for LFO 1 and make a diagonal line from button A1 to button

O16. Use two zero values in the middle for now (H8 and I9).

Now look at the matrix: that's a sawtooth wave, right? Not exactly: slow down the LFO 1

Rate, play a key, and listen. Since the row P buttons are all blue, it's actually a stair-stepped

sawtooth. Press all of the row P buttons, or every other one, or every third, to smooth out

different portions of the waveform. After this, try different values in each column to build

different waveforms. There are over 2 quadrillion combinations!

You can also create a complementary LFO waveform for LFO2 by holding its Wave Selection

arrows and using the matrix buttons as before. Use the Seq-Sync buttons to lock them both

to tempo, use the LFO division feature to alter their rhythmic relationship, route them to other

destinations in varying amounts, and don't do the math. Your calculator will melt.

To exit LFO Draw mode, use the Wave Selection arrows or the Preset, SEQ, or MOD buttons.
