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.

BLEASS Flanger harnesses the sonic characteristics of classic flanger effects and brings them fully up-to-date with a pair of flexible LFOs, variable modulation routing, an envelope generator and beat synchronisation. Classic flangers are a delay-based effect, and modulate the delay time to create the distinctive, repetitive flanged sound. But with BLEASS Flanger, multiple modulation sources are combined to create detailed, complex and evolving timbral movement within your sound. The addition of an envelope generator, which is triggered by the incoming signal, adds an additional dimension to the flanger effect, making it sensitive to the dynamics and nuances of your performances. The second LFO can take the sonic possibilities further still, with the option for it to modulate the delay’s feedback strength or stereo width. The tonal character of the effect can be controlled easily thanks to the multi-mode input filter, whilst the ability to synchronise the LFOs to the beat of your music allows you to explore completely new rhythmic and evolving effects. BLEASS’ trademark interface design ensures this powerful collection of tools are both easy and fun to work with, so you can harness their sonic versatility without ever hindering your musical creativity. And with super-efficient CPU usage, and compatibility with all major hosts and DAWs on desktop, iPad or iPhone, BLEASS Flanger is the only flanger you will ever need.
