PhaserThe Phaser automatically moves frequency notches up and down the spectrum of the signal by means of a low fre- quencyoscillator(LFO),creatinganoscillating“combfilter”typeeffect.Thiseffectisveryusefulonkeyboards(espe- cially pad presets) and guitars.TremoloTremolo/Pan creates rhythmic changes in signal amplitude. Tremolo is obtained by setting Phase to 0 degrees, and affects both channels’ amplitude simultaneously. If the Phase is set to 180 degrees, an AutoPanner effect is generat- ed, with the amplitude of one channel being raised whilst that of the other channel is lowered.VibratoVibratoisobtainedbysmoothlyvaryingthepitchofthesignaljustsharpandflatoftheoriginalatadeterminedrate. Phase controls whether the pitch of both channels is modulated together, or in an opposite direction.Rotary
