LFO 
Mopho x4 has four low frequency oscillators (LFOs) per voice. 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. 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.
