Oberheim Matrix-12 User Manual

Selecting an LFO
Pressing the LFO X button in the SINGLE/MULTI PATCH PAGE SELECT
section will give the display:
SELECT LFO FROM 1 TO 5
While this message is being displayed, the LED in X SELECT will flash on and
off, prompting you to select one of the five available Low Frequency
Oscillators. The CURRENT PAGE section of the PROGRAMMER display will
show the LFO that was last selected. You may then...
... press an X SELECT button from 1 to 5 to select that LFO
... or press the LFO X button again to select the LFO that was
selected previously-the one displayed under CURRENT PAGE. This
feature adds speed when selecting an LFO to be worked with.
Once you have selected an LFO, it will be displayed in PAGE MODIFIER.
At this point you are able to program its parameters. You may also switch
among the five LFOs with the X SELECT buttons if none of the Lower
display functions are underlined.
The M ATRIX-12 contains five independent LFOs labeled LFO1 through LFO5.
Since they are identical, we'll cover their parameters together.
SPEED
WAVE
Triangle UJaue
Square LUaue
This parameter sets the LFOs1 frequency or rate. Range is
from 0 to 63 where 0 represents the LFOs1 slowest speed
and 63 the fastest.
This parameter allows you to select the waveform of the LFO
that will be used as the modulation source.
Periodic Waveforms
TRIANGLE
This is the most commonly used waveform which can be
described as a symmetrical wave with a regular up-down
shape. This waveform is primarily used for vibrato or tremolo
effects.
UP SAW - "Up or Positive Sawtooth"
A variation of TRIANGLE where the rising (positive) portion
of the wave gradually reaches its peak then drops off sharply.
DOWN SAW - "Down or Negative Sawtooth"
An inverted variation of UP SAWwhere the wave starts at its
peak and gradually decreases.
SQUARE - "Square Wave"
Another symmetrical waveshape where the rising and falling
portions are sharp transitions. The SQUARE does not
Mpeaktf like the other waves but has equal high and low
