Use the tone
What a steady tone is good for
A tone that holds exactly where you put it, for as long as you want it, is more useful than it sounds.
Two decimals, or just a note name.
Type 442.35 Hz when that’s what you need, or pick a note and an octave and let it do the arithmetic.
Change the waveform mid-tone.
Move between sine, triangle, square and sawtooth without stopping, and hear how much of an instrument’s character is just harmonics.
No click when it starts or stops.
A short fade at each end, so a long reference tone won’t spike your speakers or your ears when you press stop.
