Drift vs Choral Lab

DRIFT is a saturation plugin with a wandering soul. The distortion curve doesn't sit still — it shifts continuously, driven by the Drift parameter, so your signal is never processed the same way twice. Warm and musical at low settings. Gritty and unpredictable pushed hard. Everything in between. — DRIVE — Pushes the signal into saturation. From gentle warmth to hard clipping. — DRIFT — The wandering parameter. Steers the saturation curve continuously over time — the higher it goes, the more the character shifts. — DEPTH — Controls how far the curve travels from its center position. More depth, more variation. — SPREAD — Widens the drift behavior between left and right channels for stereo movement. — REACT — How quickly the curve responds to transients. Low React for smooth, gradual drift. High React for transient-following distortion. — TONE — Post-saturation tonal shaping. Roll off highs or open up the top end after the drive. — MIX — Dry/wet blend for parallel saturation. — OUTPUT — Final output level after saturation and tone shaping. — AUv3 PLUGIN — Run DRIFT inside AUM, ApeMatrix, Audiobus, or any AUv3 host. Multiple instances, each with independent settings. — WORKS ON — iPhone and iPad, all modern screen sizes.

Choral Lab brings the art of four-part Bach chorale writing to your iPhone. Whether you're a composer, music student, or theory enthusiast, explore one of the most refined harmonic styles in Western music. Harmonize your melodies. Draw a soprano line on the interactive piano roll and watch Choral Lab instantly generate alto, tenor, and bass voices following authentic Bach voice-leading rules — avoiding parallel fifths and octaves, resolving leading tones, and building natural cadences. Browse 410 Bach chorales. Explore the complete corpus of J.S. Bach's four-part chorales with full score display, real-time chord analysis, and playback with rich choir sounds. Two ways to read the music. Switch between a traditional four-part score view with proper notation and clefs, or a piano roll view to see the voice leading clearly laid out across time. Mute individual voices to focus on any single part or study how voices interact. Generate original chorales. Let the app create complete chorales from scratch in any key — major or minor — with realistic harmonic progressions, passing tones, and Picardy thirds. Study chord analysis. Follow along with real-time Roman numeral chord labels as the music plays.
