So I am sure a lot of musicians struggle to fix reverb/delay time to be smooth and synced to BPM of a track. I know 2 ways of doing it:
An easier way to fix reverb/delay time is to use Delay time Calculator:
To get right delay/reverb time you just need to put BPM of your track and time signature of your track and Delay time calculator will do rest for you, in other words, he will calculate all possible reverb/delay times for you.
For instance, let's say we need to get reverb time of sound that is 120 BPM and it has the signature time of 4/4.
So from the picture we see that if your track tempo is 120 BPM and it has time signature 4/4 your reverb time should be 2000 ms.
So if you wan't to get longer reverb you multiply the time you get with Delay Calculator for how much longer reverb you wan't.
If you wan't reverb time twice as bigger,you will put reverb time of 4secounds, four times bigger 8 seconds and so on...
That's it. You will now be able to get reverb/delay time right faster and speed up your workflow. I hope this tip will help you ;)
