About

Tailsync

Features
Read full description

Make your reverb groove with your music. When your reverb tail matches your track's tempo, the decay fades naturally between beats. This creates a cleaner, more cohesive mix where the reverb enhances the rhythm instead of fighting it. Tailsync calculates pre-delay and decay times instantly based on your BPM and desired room size. Just copy the values into your reverb plugin. FEATURES - Instant tempo-synced calculations - 5 reverb sizes from tight to hall - One-tap copy to clipboard - Beautiful, minimalist interface - Haptic feedback - Works completely offline PRO TIP With iCloud Universal Clipboard enabled, tap any value on your iPhone and paste it directly into your DAW on Mac. No typing required. Perfect for music producers, mix engineers, and sound designers who want their reverb to feel musical, not random. Made with care by AKER.

MIDIWorld turns sensors and live data into MIDI control and notes. Map accelerometer, gyroscope, compass, GPS, barometer, microphone level, touch, light, proximity, and device motion into your performances. Layer weather, air quality, tides, visibility, seismic activity, place density, and market or FX-style feeds where available. Record multitrack sessions, adjust each source with per-track controls, and preview what you captured. Export Standard MIDI Files to use in any DAW or hardware that accepts MIDI. Optional audio export is available where the app supports it. Presets help you start quickly — from motion and tilt to weather, urban, health-driven, and experimental setups.
