ARHARM

ARHARM turns a single performance into a layered harmony by following its pitch and generating up to four additional voices. Choose a key and scale, then set each voice to a musical interval so the generated harmonies stay in key as the melody changes. It is designed for single-note material such as lead vocals, monophonic guitar or synth lines, and bass. Each harmony voice can have its own interval, detune, delay, pan, and level, giving you control over everything from simple backing harmonies to wider layered arrangements. FORMANT PRESERVE keeps the tonal character of the original source while its pitch changes, helping the generated voices sound more like the same performer or instrument. HUMANIZE adds independent pitch drift to each voice for less mechanically perfect layering. Unpitched details such as consonants, breaths, and pick attacks are kept at their original pitch to preserve the performance. Ten scales plus CHROMATIC mode provide both scale-aware and fixed-semitone harmonies. ARHARM includes 12 factory presets, A/B comparison, and undo, with fixed latency reported to the host.
