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

VAPolyMkII is a virtual analog bitimbral polyphonic synthesizer for iPhone, iPad and Mac. It features 16 voice synthesizer, effects, sequencer and audio visualization tools. It operates as a stand alone or as an AudioUnit Extension (AUv3). Stand Alone supports Ableton Link, MIDI and audio file export. 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 and cascaded OTA filter circuit for classic analog sound. The Effects include delay, chorus, flanger, reverb, eq and compressor. The sequencer features piano roll and parameter 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. - Main Features - Virtual analog 16 voice bitimbral polyphonic synthesizer Two type of Lowpass filter, cascaded OTA model and Sallen-key model. Patch points for modulation. Support MIDI 2.0 New User Interface built by SwiftUI for improved performance. Built-in Sequencer. 16 bar patterns per clip. Total 8 clips. Piano Roll and Parameter automation. Support Audio Unit Extension (AUv3) Works on iPhone, iPad and Mac. Support iCloud Drive to share project files between the platforms. Audio Export. Linear PCM format (AIFF, WAV and CAF) and compressed format (AAC) Support Ableton Link, Bluetooth MIDI, MIDI In / Out. - System Requirements - A13 Fusion or above is recommended.
