      What is the PHASEX0 type in Phaser?

      Is it emulating what the name would seem to be referring to?

      If it is, I don't think that Eventide would confirm it here.  Funny, I thought "crossover" when I first saw the name description.  You may be right about the origin of the XO.  I need to play around with that one the next time I demo at the Store.

      "…modulation effects use slightly different means to manipulate the signal phase, the EQ and / or a time delay. It’s the sweeping of these parameters that earmarks the effects as ‘modulation effects’. While you could move these parameters by hand and achieve the effect, most commonly an LFO (low frequency oscillator) is employed to control the speed and depth of the sweeping. In this instance then, the LFO is the modulator, while the audible signal is the carrier. While flangers and chorus usually rely on delay to create this effect, the phaser is unique because it employs a chain of ‘all pass filters’ to generate frequency notches and peaks. Sweeping (moving) these notches / peaks creates the signature sound of a phaser.

      phase-shifter (the proper name for a phaser) is made by taking an all-pass filter and automating it’s crossover frequency(the point at which the high and low passes meet, and where the phase-flipping occurs) so that it moves. Usually this movement is controlled by an LFO." 

      Very good tutorial on phasers:

      It’s a little late, but I just came across this in the PHASER “Info” tab:

      “BiPhase is based on the topology of the Mu-Tron Bi-Phase; PhaseX0 is a phase 90 clone … “
