For Drum Tuning
Use as a Reference for Drum Tuning
One-click to set a drum preset frequency, then strike the drum while the reference tone plays. When they blend without beating, tuning is complete.
Waveform Types
Sine (pure tone)
No overtones — ideal for tuning reference and ear training.
Triangle
Soft, odd harmonics — close to a sine wave, less fatiguing.
Square
Buzzy, rich in odd harmonics. Clear pitch definition.
Sawtooth
All harmonics — bright, edgy sound, closest to a real instrument.
