Read full description

The 303 lives between the sheets. Spreadsheets Synth is an acid bass synthesizer with a built-in step sequencer โ€” a cultural product of the band Spreadsheets, tuned to 313K and pointed straight at the dance floor. THE SQUELCH Sawtooth or square through a resonant filter with cutoff, resonance, decay, and accent โ€” from rubbery basslines to screaming acid leads. Add distortion for grit, then send it into orbit with the phaser and delay. THE SEQUENCER Program patterns step by step, set the line looping, and ride the cutoff live. It's an instrument for performing, not just programming. PLAYS WITH YOUR WHOLE RIG โ€ข AUv3 plugin โ€” load it as an instrument in GarageBand, AUM, Cubasis, Loopy Pro, and any AUv3 host โ€ข Standalone app with background audio โ€ข MIDI in and out, including Bluetooth MIDI NO STRINGS No account, no ads, no tracking, no data collected. Just voltage.

About

J

Read full description

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.
