How do you guys treat pre delay on reverb? I find that once I put a bit of ambience and room over my drums, I have to reduce the pre delay right down to 0 (or its lowest setting). I find that if I increase the pre delay anymore, it makes things "too wet" and sloppy. Kinda makes the drums feel like they are dragging. Do you guys use pre delay alot?

And what size do you make your room verbs? I kinda stick at around 10 meters.

I think predelay usually only sounds good on vocals and pads. Percussive stuff I generally only like predelay at musical lengths (16th note or 32nd note) otherwise it throws off the rhythm.

Thanks Psy. I see. So do I need to work out the pre delay in mill seconds via the tempo of my track? Can you give me an example say if my track was at 130 bpm? Cheers m8.

What room size do you use for a room verb psy?

So I just used that table created my Jemma. I stuck the tempo of 130 bpm in and it said that 1/16th was caculated at 0.1154 ms. So this should be my pre dealy?

room size really depends on how big you want it to sound

sorry, but you can't really generalize it beyond that.

to figure out millisecond delay values based on tempo, divide 60,000/tempo and that will give you a 1/4-note in ms. You can then divide that or multiply to get other note values. So at 130 bpm, if you wanted a 32nd-note predelay you would set it to (60,000/130/2/2/2 = 58) ms.

not sure what "So I just used that table created my Jemma" means, but it gave you the wrong delay time.

So your saying 1/32 @ 130 bpm is 58 ms? I'm confused now.

Psy, the table is in the "table" section under the Dancetech name at the top of the page.

well, i'm checkin' it out here with a 130 bpm loop and my trusty PSP42 delay and it works for me. I multiply 58 (it's actually 56.81818181....) out and it makes nice 1/4-note and 1/2-note delays for me so I think there's something wrong with DT's chart.

there's a java delay calc' too which gives ms times

It's just a proportion. Pay attention to the units for eatch quantity, and this'll make more sense:

bpm = beats per minute
1 beat = 1 quarter note (assuming 4/4)

130 beats per minute = 120beats/60sec
Invert the fraction: 60sec/120beats
Reduce (divide by 60): 1sec/2beats
solve for one beat: .5sec/beat

So there is .5 seconds PER BEAT. A quarter-note delay at 120 BPM is .5 seconds. A sixteenth note delay is then 5/4 sec or .125 seconds.

The generic formula for finding quarter-note delays is 1/(bpm * 60)

Oh, and your number for the 16th note delay at 130bpm is right, it's just got the wrong units. .1154 seconds, not ms. In ms that's 115.4 ms
