VIB
VIBRATO
The MATRIX-12 SINGLE Patch programming provides five independent LFOs
(Low Frequency Oscillators) for extensive modulation capability. In many other
synthesizers, one of the available Patch LFOs must be used if conventional
Vibrato is desired. The MATRIX-12 provides a "sixth LFO" called VIB so that one
of the five Patch LFOs need not be sacrificed to obtain this popular modulation.

The primary page of VIB contains the three most-used parameters for
defining the Vibrato.
The frequency of the VIB is variable from 0 to 63, with 0
being the slowest and 63 the fastest.
VIB provides six waveforms to be used in modulating the
destination. The first four are called "periodic" waveforms
because they repeat in even patterns or cycles. The last two
are called "aperiodic" characterized by disorderly patterns
that do not repeat with any regularity. For more detailed
descriptions of these waveforms, refer to the LFO X section
of this manual, Page 132.

NOISE
You should note that the NOISE modulation is not affected
by the SPEED adjustment.
The amplitude or output level of VIB is selected with this
parameter. AMP is also referred to as "amount" or "depth".
You should notice that this parameter defaults to a value of 0
because LEVER2 or a MIDI Vibrato Wheel is normally used to
bring vibrato into the Patch. The operation of LEVER2 is set
