174 BPM half note — 689.66 ms

Reverb and LFO use the same number

Set a reverb’s pre-delay and decay to these figures and the tail lands on the beat. LFOs are often dialled in hertz rather than milliseconds, so the table also gives 1,000 divided by the length — that is the rate to use for a tremolo or auto-pan locked to eighth notes.

Worth knowing

• One beat is 60,000 divided by the tempo; every other note is a multiple of it.
• A dot adds half the value back; a triplet is two thirds.
• LFOs are often set in hertz rather than milliseconds, so that figure is here too.
• The bar figures assume a 4/4 time signature.
