thumb|LFO controls (Low Frequency Oscillator) An LFO is used to modulate parameters such as amplitudes, frequencies or filters. Controls thumb|LFO controls, shape selection menu open The main LFO controls are: FREQ: frequency = LFO speed DEPTH: LFO amplitude START: start phase = position the LFO starts at DELAY: delay between the note start and the LFO start shape: envelope shape can be sine, triangle, square, ramp up, ramp down, exp1 down, exp2 down Other controls: STR: stretch = controls how much the LFO frequency changes according to the note's frequency when negative, the LFO frequency is decreased on higher notes when zero, the LFO frequency is the same on all notes when positive, the LFO frequency is increased on higher notes A.R.: amplitude randomness F.R.: frequency randomness SYNC: continuous mode = when on the LFO won't be reset on each new note but will synchronize
