With Additive Drum Machine you can create drum beats using the concept of “additive rhythm” in combination with the sounds and ease of use of a traditional drum machine. Construct step sequences of any length and structure by the chaining of "long" and "short" beats. Then switch on and off individual steps to create a drum pattern. Whether used as a practice tool or composition sketchpad, its intuitive interface allows you to easily make drum patterns that use odd meters, symmetrical and asymmetrical rhythmic structures, and various subdivisions of the pulse. With Additive Drum Machine your musical imagination is the limit.

E-Chorus is a four-voice ensemble 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. Four modulated delay voices use different base delay times and rate offsets to create a dense, smooth sound without relying on one obvious sweep. The result can move from focused widening to a spacious animated wash while keeping the source present. FEATURES - Four independently timed ensemble voices - Rate control from 0.1 to 5 Hz - Equal-power Depth dry/wet blending - Width control from focused mono to spacious stereo - Instrument and line input modes - Output level from -12 to +12 dB - Optional 2x and 4x oversampling - Mono and stereo processing - 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. E-Chorus works well on synthesizers, electric piano, guitar, vocals, pads, and other sources that need width without losing their center.
