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

The synthesizer consists of two 8 voice synthesizer, which features two oscillators, two ADSR envelopes, resonant high pass and low pass filter and an amplifier per voice. The oscillators features continuously variable wave shape and wide variety of modulation. The filters are modeled on the Sallen-Key filter circuit for classic analog sound. The Effects include delay, chorus, flanger, reverb, eq and compressor. The sequencer features piano roll and automation editor to program 16 bar pattern per clip. Project files can be saved in iCloud Drive, so that the project can be accessed from iPhone, iPad or Mac.
