Fórmula
Quarter delay = 60 000 / BPM ms. Frequency = 440 × 2^((n − 69) / 12) Hz, where n is the MIDI note number (A4 = 69 = 440 Hz).
Perguntas Frequentes
What MIDI note is middle C?
MIDI 60 is middle C4. A4 is 69 and corresponds to 440 Hz — the tuning reference for the equal-temperament formula.
How do I use the delay in a DAW?
Set the delay plugin to the quarter or eighth value so echoes fall on the beat. For a triplet feel, multiply the quarter by 2/3.
Is this 12-TET only?
Yes. For historic or microtonal tunings use a different base and ratio in the formula.
