You can use the Wave buttons to choose different waveforms for LFO 1 and LFO 2. The table outlines how these waveforms can affect your sounds.
Tip: Try different waveforms while a modulation routing of Pitch is engaged and running.
Waveform | Comments |
|---|---|
Triangle | Well-suited for vibrato effects |
Sawtooth | Well-suited for helicopter and space gun sounds. Intense modulations of pitch with a negative (inverse) sawtooth wave lead to “bubbling” sounds. Intense sawtooth modulations of lowpass filter cutoff and resonance create rhythmic effects. The waveform can also be inverted, resulting in a different start point for the modulation cycle. |
Rectangle | Use of the rectangular waves periodically switches the LFO between two values. The upper rectangular wave switches between a positive value and 0. The lower wave switches between a positive and a negative value set to the same amount above or below 0. You can achieve an interesting effect by modulating the Pitch destination with a suitable modulation intensity that leads to an interval of a fifth. Choose the upper rectangular wave to do so. |
Sample & Hold | The two lower waveform settings of the LFOs output random values. A random value is selected at regular intervals, as defined by the LFO rate. The upper waveform steps between randomized values (rapid switches between values). At its lower setting, the random wave is smoothed out, resulting in fluid changes to values. The term Sample & Hold (S & H) refers to the procedure of taking samples from a noise signal at regular intervals. The values of these samples are then held until the next sample is taken. Tip: A random modulation of Pitch leads to an effect commonly referred to as a random pitch pattern generator or sample and hold. Try using very high notes, at very high rates and high intensities—you’ll recognize this well-known effect from hundreds of science fiction movies. |
