3DSynth! A chromatic touch synthesizer and on-device recorder. Chromatic by design - 3DSynth lets you play all notes and frequencies continuously—not locked to MIDI steps—so you control pitch directly with your finger like a real instrument! Real-time, responsive play - Low latency and immediate feedback keep your phrasing natural and expressive while you glide and shape the note in motion. Shape your sound - Choose different instruments (oscillator, FM, plucked), sculpt with ADSR and add effects like reverb, modulation, delay, distortion, and EQ! Record on device - Capture your takes directly to the app’s local recordings folder for sharing and backup. **Important** Deleting the app removes its local data, including recordings and settings. Export anything you want to keep before uninstalling or resetting the device. Enjoy and thanks for downloading!
Tailsync

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.
