You choose the pitch and the app plays 3 octaves and 3 fifths intervals for it. The sound is generated with sawtooth oscillator synth and this gives the incredible amount of harmonic material to play with. Consider it as an electronic version of indian tanpura or simply the Shruti box.
- Swipe the top section to choose your root pitch — the central tone everything else builds around.
- Tap any voice cell to toggle it on. Each voice is an independent instrument.
- Each voice has 4 control quadrants — drag to shape its sound:
- VOL/PAN — volume and stereo position
- LP/Q — filter brightness and resonance
- AF — auto-filter rate and depth
- CHO — chorus modulation depth
- Use the master volume knob in the top bar for overall level.
- Let the voices breathe — each has its own subtle LFO movement.
- Sing, tune, or meditate with the evolving harmonic landscape.
