J-Chorus is a vintage BBD-style chorus for iPhone and iPad. Use it as a standalone audio app or insert the included AUv3 effect in a compatible host such as GarageBand. Its circuit-informed processing models the character of a 256-stage BBD path, op-amp modulation source, and compander. Three classic modes provide bright movement, deeper richness, or a combined wide stereo sound. Aging adds adjustable clock instability and noise for a more weathered response. FEATURES - Mode I, Mode II, and combined I+II - Adjustable Aging for BBD jitter and noise character - Equal-power Depth dry/wet blending - Adjustable input gain - Instrument and line input modes - Optional 2x and 4x oversampling - Standalone iOS/iPadOS app - AUv3 audio effect for compatible hosts TRY BEFORE UNLOCKING The app provides 10 minutes of full-featured active use, shared between the standalone app and AUv3 extension. Demo time advances only while audio is actively processing. A one-time, non-consumable In-App Purchase unlocks unlimited use in both formats. Restore Purchases is available in the standalone app. J-Chorus adds rich stereo movement to synthesizers, guitar arpeggios, electric piano, vocals, pads, and other melodic sources.
