Sawtooth LFO
The sawtooth LFO increases linearly until a certain point when it jumps back to its original value. This
sudden jump creates a strong sense of rhythm, which is why the sawtooth LFO is often used in
synthesizers and filter effects that are synchronized to the beat of the song. By default, this LFO
shape is what is known as a rising sawtooth shape, which means that the value rises linearly from the
min value to the max value, and then resets again to the min value:
The shape of the sawtooth LFO can be changed from a rising sawtooth to a falling sawtooth by
inverting the depth parameter:
