Set a delay to the tempo
Echoes that land on the beat need milliseconds, not knob positions — convert BPM into note-length delay times.

The job
A delay plugin shows milliseconds while the song is in BPM. A quarter note at 120 BPM is exactly 500ms — set that and every echo lands on the next beat instead of smearing between beats.
Picking a note value
Straight eighths sit tight inside the groove; dotted eighths skip a beat and create the bouncing “triplet-feel” echo common in guitar lines; triplets divide the beat into three for a rolling feel.
The table also gives Hz — the same interval expressed as a frequency — for LFOs and effects that sync by rate rather than time.
What is not modeled
Pre-delay, feedback, swing/shuffle, and plugin latency change the audible result even at perfect values. Tap tempo differs too: it averages your taps, while this table assumes the song holds a fixed BPM.
