Hi! Please understand that the method I described will cause your delay reoeats to be equivalent to different note values,because it's tied to the tempo or BPM(beats per minute) of your music.You COULD use it for reverb decay times as well,but that's why I said it's a subjective thing because a reverb that is exactly timed to the tempo may or may not be appropriate for some kinds of music.For one thing,it's not very natural.BUT you might want to experiment using the calculation to set the PRE-DELAY function of your reverb;sometimes this can be effective as well.Cheers!
