Hey hey, this is about using four LFOs.
* controller side-chaining: use one LFO to modulate another LFOs speed. Applied with care, you add some randomness and "analogue" feel.
* Sequencing was mentioned, set the LFOs to sqaure wave and the same tempo, manually set the phase, so they span a full cycle and apply the LFOs to all four oscillators in turn with different amounts. You get a sort of sequence.
* Two LFOs with slightly different speed (and optionally different amount) on two delays (best stereo panned) can really do a wonderful chorus.
* The dubstep warbles and wobbles: tempo sync your LFOs, but set them to different divisions of the clock. Tip: make at least one of them a tripplet feel. Allow to change the amount by aftertouch or expression pedeal, modwheel or the touch sliders... You get some expressive dubstep=like performance sound.
* Bouncing ball effect: apply one LFO (slow saw tooth/ramp up) to another LFO's (square wave) speed. Apply that modulated sqaure wave LFO to some sort of volume and you get a sort of "bouncing ball" effect.
* should you run out of LFOs with all the fun: you can always loop the envelopes or try to apply LFOs with different amounts to other things through the mod matrix.
Happy oscillating, Ffanci
