Do you remember the single most iconic phaser you've ever heard? For the first time, there's a good chance of finding that exact sound captured in a plugin. FEATURES: • Faithful reproduction of a legendary 4-stage phaser pedal from the late 70's - early 80's • Complex effects can be built using composite LFO's, parallel phaser structures, as well as an independent modulation system for the sweep range • Barberpole or "Shepard" phaser included: infinitely rising / falling modulation that can optionally be combined with sweep range modulation • Strong, rhythmic / syncopated patterns can be created by configuring different LFO frequency ratios within the various modulation sources • Mid-Side modes allow adding special phasing effects to stereo sounds • Exact visualization of the notch filters' real-time frequency response, with different stereo options • Exceptional multirate performance: results are less sampling rate-dependent than what's currently available with most digital phasers (even from major manufacturers) • Designed to be an anthology app extensible with additional hardware-based or synthetic analog models in future MIDI NOTE EVENT RECEPTION: RealPhase can accept MIDI note messages, syncing an envelope-based modulation source to note on and off events. This makes it easy to use RealPhase as a powerful analog modeling OTA-based resonant notch filter with any synth or sampler. PLEASE NOTE: • An Audio Unit v3 compatible host app is required to use this plugin • Supported sampling rates: 44.1, 48, 96 kHz
