ZynAddSubFX/LFO

An LFO is used to modulate parameters such as amplitudes, frequencies or filters.

LFO controls (Low Frequency Oscillator)

Controls

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
