The Kontakt Interface has a control for the phaser-speed which simultaneously changes the speed of the three different LFO's that control the swirly madness.
The low end can be turned into an analogue-bass, also with controls on the interface.
The mod-wheel fades from the full phaser to a crunched, band-pass filtered sound, and pitch-bend does double duty to pitch-bend bass-notes and low-pass filter the rest (listen to demo, which involves only a single track, for examples).
