Reverb & Pre-Delay

Pre-delay values and decay times measured in 4/4 bars at the current tempo.

Tight / Vocal — 1/64 pre-delay

Natural / Plate — 1/32 pre-delay

Atmospheric / Hall — 1/16 pre-delay

1 Bar (4/4) —

2 Bars (4/4) —

4 Bars (4/4) —

Starting points

Pre-delay: try adding space between the dry signal and the reverb when you want a clearer attack.
Decay: try a 1- or 2-bar value, then shorten it if the tail masks the next phrase.
Vocals: 40 ms or more of pre-delay can leave more of the dry attack before the reverb begins.

Metric Modulation

Calculate the new BPM when one note value becomes another.
