BLEASS Voices is a vocal processing effect for pitching, transforming, doubling and harmonizing vocals and other sources. With 12 pitch-shifted voices and detailed control over pitch, formant, tone, width and placement, it can move from subtle vocal enhancement to dense harmonies and radical transformations. Four harmonized voices can be transposed independently by up to one octave in either direction or fixed to a chosen pitch. The remaining eight voices can be triggered via MIDI, turning incoming audio into a playable vocal instrument. MPE support brings expressive control to performance, making it possible to create vocal chords, realistic glides, trills and other pitch-based articulations directly from a compatible controller. Two LFOs, an envelope follower and a pattern sequencer add modulation and movement, extending BLEASS Voices beyond conventional harmonizing into more synth-like vocal processing. All voices can use intelligent pitch correction based on a selected key and scale. Each voice also has an independent output bus, allowing individual voices to be mixed and processed separately. BLEASS Voices works with fundamental frequencies from 66 Hz to 5.2 kHz, making it suitable not only for vocals but also for a wide range of instruments. A Real-Time mode provides the low latency required for live performance and recording. BLEASS Voices can be used as an AUv3 plugin on iPhone and iPad. BLEASS Voices is also available for Windows, macOS and Linux. More information, technical specifications and tutorials available on https://www.bleass.com/voices/
