The ES1 LFO Section

LFOs are very powerful modulation sources. We’ve used them to modulate cutoff frequency, pitch, and FM intensity, and we’ve even used them to create frequency and amplitude modulation sidebands. Every LFO we’ve used to this point has been a sine wave generator with no more than two possible destinations. The ES1 LFO goes so far beyond what we’ve seen in the other Logic synths that both it and the ES1 modulation envelope (which is covered in the next section, “The ES1 Modulation Envelope”) truly reveal the power of flexible modulation routing. Figure 7.12 shows the ES1 LFO section.
