Phase-shifted polyphonic LFO
LFO x EG (Surge XT) has a knob for phase control and is polyphonic, so it can produce up to 16 phase-shifted LFOs in parallel. Four LFOs are shown in the example below. The number of polyphony channels can be set in the context menu.
Phase shifts (per LFO) are introduced by sending a polyphonic signal (e.g. a fixed value per channel using docB’s PLC) to the Phase knob via the module’s modulation system (e.g. MOD 2 port).
Phase can be shifted to the right or left with -/+5V, which yield phase changes of -/+ 180°.
For changes to take effect, a gate signal needs to be sent to the Gate input, resetting the phase to the specified value. The gate can either be polyphonic or monophonic. If monophonic, the menu item “Polyphony > No Trig or Trig Chan 1 Triggers All” in the context menu needs to be selected.
A polyphonic gate signal can be generated as usual, e.g. using POLYMULT (Bogaudio).

Addendum: Voltage Range (Sparkette’s Stuff) is good for creating swarms of evenly spaced phase shifts.
