Not a toy. Music tools that work. OSE (Outhentic Sound Engine) is an instrument and toolkit for people who play. Synth, recorder, piano roll, metronome, tuner — eight focused tools that fit in your pocket and complement the desktop DAW you already use, rather than replace it. Everything runs on your device. PLAY • Expressive multi-touch synth with a real DSP chain — filters, envelopes and effects you hear live. • 140+ instruments and presets across keys, bass, pads, leads, plucks, drums and more. • Drum-pad, piano and split/layer layouts. • USB and Bluetooth MIDI keyboards. RECORD & EDIT • Record your playing as MIDI and arrange it in a piano-roll editor — move, quantize, transpose and edit velocity. • Audio recorder with a real-time effects monitor: hear your effects while you play. • Audio editor with restoration tools — declick, declip, denoise, normalize — plus cut, fade, speed and pitch. PRACTICE & MEASURE • Chromatic tuner — fast and accurate, with reference tones. • Metronome with simple and complex meters, subdivisions and savable presets. • Signal generator — sine and other waveforms, sweeps and a built-in timer. • Sound-level meters — SPL, FFT spectrum, spectrogram and peak hold.
