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.
