Source: https://docs.aden.space/docs/help/more/tempo

A free tempo tool at aden.space/tempo. Type, step or tap a tempo, hear it as a click, and copy the length of every note value, straight, dotted and triplet, in milliseconds for delays and pre-delay or in Hz for LFOs.

## What it is [#what-it-is]

Delay times for a tempo, without the maths. Open `aden.space/tempo`, or search "BPM to ms" in ⌘K. No account needed.

* **The tempo**: type it, use − and + (or the arrow keys in the field), or tap it: press **Tap** in time, or T anywhere on the page. A pause of two seconds starts a new count.
* **Hear it**: the metronome button plays a click at the tempo, and follows it as it changes.
* **Note lengths**: every note from a whole note to a 32nd, straight, dotted and triplet. Switch between ms (delays, reverb pre-delay) and Hz (LFOs, tremolo). Press a value to copy it.
