LFO

Mopho has four low frequency oscillators (LFOs). The LFOs can be free-
running, synced to keystrokes, or synced to the sequencer and MIDI clock. To
edit the LFO parameters, choose LFO in the Modulation section.

LFO Select: 1, 2, 3, 4

—Chooses the LFO to edit.

Tip: The four numbered lights above the Frequency knob pulse at the
frequency of the corresponding LFO. This can be a great aid in knowing
which LFO to select for editing.

Destination

—See Modulation Destinations on page 33 for a list of possible

destinations.

Amount: 0...127

—Sets the amount of LFO routed to the destination.

Shape: Triangle, Reverse Sawtooth, Sawtooth, Square, Sample and Hold

—The

waveshape of the LFO. Sample and Hold generates a random value that changes
once per cycle.

Frequency: 0...150

—Sets the LFO frequency. Speed ranges from slow (30

seconds) to very fast—at 90 (8 HZ, C-2) and above the speed steps in semitones,
up to 150 (261 Hz, middle C).

Note: Some of the analog functions may not respond well to the fastest
LFO speeds, due to speed limitations of the control voltages; but they
will certainly generate some interesting sounds.

Clock Sync

—When on, the LFO syncs to the sequencer and clock—either the

internal clock or an external MIDI clock. When synced to the internal clock,
BPM and Clock Divide both affect LFO frequency. When synced to an external
clock, the external clock rate and Clock Divide affect the LFO frequency.
Editing Frequency shows the values in the following table.
