Turn a musical tempo into a usable time
Enter a quarter-note tempo in BPM, then choose a note and rhythm. The calculator returns the interval in milliseconds for a delay, gate or other time-based control.
Choose the beat before the note
BPM means beats per minute. Here one beat is a quarter note. Dividing the 60,000 milliseconds in a minute by BPM gives the quarter-note duration. A half note doubles it; an eighth note halves it.
In this expression, t is the quarter-note duration in milliseconds and b is the tempo in BPM. A dotted note lasts one and a half times its straight value; a triplet note lasts two thirds. Select the note value first, then the rhythmic variation.
Three settings you can check by ear
At 120 BPM, a straight quarter lasts 500 ms. A straight eighth lasts 250 ms, so a free-running delay at 250 ms repeats twice during one quarter-note beat.
At 128 BPM, a straight eighth lasts 234.375 ms. Add the dot and it becomes 351.5625 ms, displayed as 351.6 ms. This places the repeat later than a straight eighth.
At 90 BPM, a quarter-note triplet lasts 444.4 ms after display rounding. Three such intervals take the time of two ordinary quarters. The calculator's 2.25 Hz reading describes that same repetition speed.
What the number does not choose for you
The calculation retains full precision and rounds only the displayed milliseconds to one decimal place; seconds and hertz use up to three. If a device accepts only whole milliseconds, round the final value once.
A score can mark a dotted quarter as the beat, especially in compound meter. Do not enter that marking as if it meant quarter notes per minute. This tool also does not infer swing or changing tempo. If your effect has Sync mode, selecting the note symbol there may be simpler than entering milliseconds.
Questions about tempo and intervals
The beat unit and note symbol matter as much as the BPM number.
Why divide 60,000 by BPM?
A minute contains 60,000 milliseconds. BPM counts quarter-note beats in that minute here, so division gives the time for one quarter.
Is a dotted eighth the same as an eighth-note triplet?
No. The dot multiplies a straight eighth by 1.5; a triplet multiplies it by two thirds.
Does a 3/4 bar change the quarter-note duration?
No. At the same quarter-note BPM, each quarter keeps its duration. The bar contains three quarters rather than four.
How do I use the hertz value?
Use it when an LFO or tremolo control asks for frequency instead of period. A 250 ms interval repeats at 4 Hz.
Does this pick the right delay for a song?
It calculates a rhythmic interval, not a mixing decision. Listen to how the repeats interact with the performance.
