BPM → delay/reverb (ms)
Enter the song's BPM: get the milliseconds (and Hz) for each value, to use for delay and reverb in time.
What it's for
To set delay and reverb «in time» with the song: at a given BPM, each note value (1/4, 1/8, triplets…) maps to a precise time in milliseconds.
How to read it
1/4 is the quarter note (the beat), 1/8 the eighth, «.» means dotted (duration × 1.5), «T» a triplet. The Hz are for synced filters or LFOs.
