Each of Omnisphere’s LFOs can have its own waveshape. There are nine available LFO waveforms.

Sine – A smooth c-shape that begins positive and then curves negative and back again. Useful for sweeps and vibrato.
Triangle – A positive/negative-shape like the Sine, but without curvature. Useful for sweeps and vibrato.
Square – Starts at maximum positive value and then drops to maximum negative value. Useful for trills and pulsing effects.
Rounded Square – A smoothed Square wave. Ideal for smooth pulsing.
Ramp – A linear slope from highest to lowest to highest value. This waveform is also frequently referred to as a sawtooth wave. Useful for sweeps.
Reverse Ramp – A linear slope from lowest to highest value. This waveform is also frequently referred to as an inverted sawtooth wave. Useful for reverse sweeps
Sample and Hold – Steps through random values. Useful for analog synth effects.
Heartbeat – Modeled after a human heartbeat
Noise/Random – Similar to Sample and Hold, with random values, but doesn’t stop—the values change immediately. Useful for adding chaos.

The waveforms can be changed by clicking the UP/DOWN stepper buttons or by clicking on the waveform itself, which will display the waveform selection menu.
