summary: |
  Four related LFO channels with cross-modulation and per-channel VCA behavior.
  Main sets global LFO rate from very slow to low audio range (AudioOut1 fastest, CVOut2 slowest).
  X sets cross-modulation intensity; Y crossfades each output with an inverted neighboring channel.
  PulseIn1 or Z up pauses motion; PulseIn2 or Z down randomizes phases.
