Melody / Help / Modulation / LFO
LFO
Low-frequency oscillator — a modulation SOURCE. Seven shapes (0 sine, 1 triangle, 2 saw-up, 3 saw-down, 4 square, 5 sample & hold, 6 random), variable Rate, Depth, and uni/bipolar output. Melody-owned (lfo-rt), re-derived from automation/modulation. Wire its output into a node's modulation port — a Wavetable's Freq for vibrato, Morph to scan, a filter's cutoff for a sweep; scale the swing with a gain node for wider ranges. Its own Rate and Depth ports accept modulation too (an envelope into Depth gives delayed vibrato).
