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!
