Delay Time Calculator: BPM to Milliseconds with Tap Tempo

Set your delay in rhythm. Enter a tempo in BPM, or a delay time in milliseconds, and get the delay time for straight, dotted and triplet note values. No tap tempo on your pedal? Tap the tempo here and copy the value.

How to use the delay time calculator

Type the tempo of your song, or tap it, and the calculator returns the delay time in milliseconds for each note value. Enter the number on your pedal, rack unit or plugin. You can also work backwards: type a delay time in milliseconds to find the tempo it matches.

Most pedals ask for a time in milliseconds. If yours accepts whole numbers only, the values above are rounded to the nearest millisecond, which is accurate enough for performance.

Why delay time should match the tempo

A delay repeats your sound after a set time. When that time fits the tempo, the repeats land on subdivisions of the beat and add to the groove. When it doesn’t, the echoes fight the rhythm and the result feels rushed, late or muddy, even if each note you play is perfectly in time.

This matters most for solo instruments, live looping and anything played with a drummer or backing track, where the delay becomes part of the rhythm section. Matching the delay to the tempo keeps your sound clear, lets you use more of it, and makes your playing feel tighter.

How to convert BPM to milliseconds

The delay time of a quarter note in milliseconds is 60,000 divided by the BPM. At 120 BPM, that is 60,000 / 120 = 500 ms. Every other note value is a multiple of that number.

• Straight: a whole note is 4 × the quarter note, a half note 2 ×, an eighth note half, a sixteenth a quarter.
• Dotted: multiply the straight value by 1.5.
• Triplet: multiply the straight value by 2/3.

Example at 120 BPM:

Straight, dotted and triplet delay times

Straight delay

Straight values (quarter, eighth, sixteenth) give regular echoes that reinforce the pulse. A quarter-note delay is a clean, spacious repeat; an eighth-note delay fills the space between beats.

Dotted delay

A dotted note lasts one and a half times its normal length. The dotted eighth delay is a classic choice for rhythmic, syncopated echoes that seem to move ahead of the beat, and it works especially well with sustained or single-note lines.

Triplet delay

Triplet values divide the beat in three. They suit shuffle, swing and compound-time grooves, and they add a rolling, circular feel to melodic phrases.

Delay pedals without tap tempo

Many multi-effects units and compact pedals do not sync the delay to a tempo. Units like the Zoom A1X Four or the Sonicake Pocket Master often need the delay time dialled in manually, in milliseconds. This calculator gives you the exact number to enter, so your delay stays in the groove even without a tap tempo function.

If you play violin, viola or cello through a Zoom A1X Four, my Zoom A1X Four presets pack includes 30 patches built for string instruments. Pick a preset with a delay, set its time with this calculator, and save it for each song.

Delay time tips for violin, guitar and live looping

• Start with the quarter note or the dotted eighth. They leave room for your playing while adding movement.
• Keep the feedback low in busy music. Fewer repeats mean a clearer mix.
• Lower the mix for fast passages. Longer delays blur quick notes, so use shorter values or a smaller mix level.
• Tap the tempo from the drummer or backing track before the song starts, enter the value, and test it against the groove.
• When looping, set the tempo first. Your delay and your loops will then share the same pulse.

Frequently asked questions

What is delay time in milliseconds?

Delay time in milliseconds is how long it takes for the delayed signal to repeat after the original sound. When it is synchronized to the tempo of the song, the repeats feel musical and rhythmically tight.

How do I convert BPM to delay time?

To find the delay time of a quarter note, divide 60,000 by the BPM. For example, at 120 BPM the delay time is 500 ms. This calculator does the conversion for you and shows the other note values.

What if my delay pedal doesn’t have tap tempo?

Use the calculator to find the right millisecond value and enter it manually on your pedal. This is common with compact multi-effects units and budget pedals.

What are dotted and triplet delay times?

They are rhythmic variations of the main beat. A dotted delay is 1.5 times the straight value and creates a wide, syncopated feel. A triplet delay is two thirds of the straight value and suits shuffle and swing grooves.

Can I use this calculator for live performances?

Yes. The tap tempo button works on phones and computers, so you can match the tempo quickly during rehearsals and live shows.
