PhaseThree is a detailed model of the MuTron Bi-Phase, with all the lovely sound of that unit (along with its foibles and quirks.) It is worth noting that, due to aging factors, no two Bi-Phase hardware units sound alike; we found the best and most tuneful one we could lay our hands on, bought it for a faintly ridiculous price, and took it apart to see what made it tick. Like you do. The result is a painstaking digital copy of the original unit, down to the unique sweep of its LFOs. With the latest version, we have departed from the original and added 12-stage phasors in addition to the six-stage versions found in the hardware units. (We feel that 12-stage phasors have a more modern sound that people expect in a current phasor, and that the six-stage versions in the original were somewhat lacking to the modern palette.) Features » Standalone (with Inter-App Audio) and AudioUnit V3 versions included. » Perfect model of the original Bi-Phase, down to the response of the vactrols. » The unobtanium Bi-Phase expression pedal is modeled as a separate parameter, for control by your favorite modulation source. » 12-stage phasor option for each channel, in addition to the original 6-stage phasors. » XML-based cross-platform preset manager, with copy and paste. (You can even move presets between the iOS version and the desktop version with Handoff.) » Entirely vector-based resizable high-resolution user interface.
