Time Delay FX..... Echo, Delay & modulation FX such as Chorus & Flanging can provide masses of variation and cool sounds to your tracks.

The Delay Unit has these basic controls:

  • INPUT.................Sets the level in to the unit to avoid distortion and get a high enuff level.

  • DELAY TIME..........Sets the time between the original sound and the first echo.

  • FEEDBACK....................Sets how many times the echo will repeat.

  • MODULATION RATE........Sets how fast the echo repeats will rise and fall in pitch (if at all)

  • MODULATION DEPTH....Sets how high & low in pitch the echo signal will rise and fall (if at all)

  • OUTPUT..........................Sets the level of the signal out


Delay Units come as either...TAPE....ANALOG...or....DIGITAL......All the techniques are the same for each...so we will go with Digital, as it's the most common unit people own..... Just bear in mind, that Tape & Analog units each have a distinctive sound.... Analog units being similar to digital... but harsher & metallic in sound....while Tape units give you that old 70's dub plate sound... excellent for feedback.

There are two types of digital delay. Those with knobs, and those without. I prefer a cheap one of each, as long as they're quiet.

Each type will perform certain jobs well , that the other will not. There are some delay FX that both type of unit will do.

IMPORTANT : Always have a dedicated stand-alone delay unit. This enables you to use the delay FX on individual instruments in the mix... If you can only afford one delay unit, make the first one a delay with knobs if possible.... If it doesn't have knobs, then you will not be able to do half the FX here.

Check out what each type of unit will do for you.





STATIC TIME DELAY

These units with cursors, once set to a time, stays there... rock solid, and have a readout screen, so you can set the right time.
The static timed delay is what makes any style of dance tune kik. It makes your beats and synth lines really roll in a fluid way, and is essential for dub. Also delay timing makes or breaks a vocal in a mix.

The way I learned about delay was from doing reggae sessions. Swing beat was created by The Funky Dreads in the UK; a team brought up doin reggae, and applying the same techniques to dance beats. You take one of the standard reggae delays, and put it on a drop beat... Hey-presto.... a swing beat.

I use a Yamaha D1500, it was cheap and is rock solid, and has storage for about 7 preset delay times. As far as I know, it's the only cheap dedicated delay that Yamaha made with MIDI control, (which I don't use). I paid 100 pounds sterling for mine, s/h.....a bargain. You could use an SPX, or an Alesis Multi-FX unit.

but it is a waste....You need the delay as a seperate unit, so you can apply the FX to individual sounds

Delay units are cheap, and will do more to kik up your beats & synthlines than any amount of things.

Also, they will save you hours in programming time if you are trying to get fluid funky beats, synthlines, or racey mental beats and lines.

Timed delay, will often create cross-rhythms you would never have come up with by programming, and as I said before, delay timing is critical in a mix especially on vocals....






STATIC TIME DELAY FX TIPS

THESE FX ARE BEST PERFORMED WITH A DELAY UNIT WITH A READOUT DISPLAY AND CURSORS


TO SET THE DELAY TIME...
Send a click at a given BPM to the delay, then adjust the delay time until you get a cool cross-rhythm. (See bottom of page)

TO APPLY THE EFFECT...
Add a touch to individual instruments via the Aux send on your mixer. Choose for the send a post fade one, (that is where when you lower or cut the channel fader for a sound, the aux send also lowers or cutz).....

Try punching a channel in and out, and just listen to the rhythmic delay wind off into the distance.(standard dub stylee) You can play with this stuff for ages live, great for intro's and breakdowns......

Another thing you can do, is bring the delay back through a spare channel on the desk, and add reverb to it. (if your FX returns do not have aux sends on them. If you do this, you can also do the old delay feedback routine.....


FEEDBACK...
Turn up the aux send TO the delay, on the delay RETURN channel.

This creates feedback!!....It is more harsh than the delay feedback you get on old dub plates where they used tape delays, but still....You can roll off the top end drastically.....Be careful, this can fry your tweeters!


APPLYING FEEDBACK...
On a breakdown section, either:

Flick the aux send TO the delay for a vocal phrase or hi-hat or something, and right after you do this, kill the channel....or:

Open and close a channel (where the aux send to the delay is already turned up) at the right moment, just like you're hitting a drum beat.

The delay now has the phrase captured and if you have set a fairly long feedback time, say 80 - 95%, you should hear it echoing away.

Now.... go to the mixer channel that the delay is coming back on, and as the phrase repeats, turn UP the aux send TO the delay... prepare for f-e-e-e-e-dback!!

YOU CAN GO TO THE... DELAY-TABLE... WHERE YOU WILL FIND A LIST OF DELAY TIMES - BPM TIMES, THAT WILL GIVE YOU EXCELLENT CROSS-RHYTHM DELAYS.





VARIABLE TIME DELAY

These units because they use pots, tend to be less reliable when it comes to holding a delay time, and rarely come as cheap models with a readout. without which it's a bloody nightmare searching for the right timing, especially in a live set....

However, where these units score, is they got knobs!... for wild 'n' wacky FX, such as the vocal stuff in Jungle.

I remember some years ago, doing some mixing for some reggae tracks. The studio had a digital delay with knobs, and I had gotten into wierd stuff with the delay....stuff like heavily feedbacked close delays of around 50 - 100 ms., rising and falling on vocals or snare drums; and using the hold function, to capture a sound, then just letting it repeat while screwing the delay time up and down to get that effect like at the end of Electric Ladyland...(Hendrix)...

I did some of this wierd shit which now people would use all the time on vocals and other sounds in Jungle & drum & bass... The guys listened... and listened......"Nah man... just we'll take the normal mix...."

I'm not saying I invented it or anything, it's simply that everytime you hear a "new" sound people all over have been doing it, and soon it gets through... But you do find that people tend to come up with cool stuff if they ain't thinking what they SHOULD be doing....

Anyhow....the delay with knobs....cheap ones.....not too reliable when it comes to holding a solid time, but great for all the sort of stuff I just described......And thats how it goes, Guys on a sound playing some Jungle...someone brings a cheap analog delay to the sound.....wack the mike through it.....and bend the crap out of the knobs.....GREAT LAUGH....someone in the posse does the same thing with more timing and dexterity, and a style is born.....You dont need $1000 expensive delay units...






VARIABLE TIME DELAY FX TIPS

THESE FX CAN BE ONLY BE PERFORMED WITH A DELAY UNIT WITH KNOBS


SNARE HITZ-Z-Z-Z-Z-Z-Z-Z-

Set the DELAY TIME to about 100ms (milliseconds=thousandths of a second) delay time, something short.
Then set the FEEDBACK to about 50-60% whatever decays right for you.
Tweak a send to the delay from the snare mixer channel....The sound should be kind of like it's in a metal bucket....

You can vary it by leaving the AUX SEND to the delay on the snare channel up, and varying each hit on the snare or every other hit, by adjusting the DELAY TIME, or leave the DELAY TIME short, and adjust the feedback....You know ?...Like with the snare on the third beat......1 - 2 - TWANG - 4.......1 -2- TWAAAAAAAAAAANG.....1 -2 - etc....

Next you can go to the modulation section on the delay, and set the MODULATION RATE to a low or almost zero setting, and the MODULATION DEPTH to something higher, maybe 40-50%...
The snare effect should wind UP....and DOWN....

Adjust the MODULATION RATE, to match the tempo of the track, or so that the rise and fall times how you want it to in the context of the track.....Check it out...


JUNGLE.!!!.....

You can play around, and add this FX to vocals or whatever......For the JUNGLE bit, let the vocal through at a medium feedback level, then turn the FEEDBACK control UP, at key phrases, or at the end of a chat line.....OR JUST GO MENTA-A-A-A-L........with the DELAY TIME, FEEDBACK, and the MODULATION controls.....AWOOAH...


ELECTRIC LADYLAND

This works if your delay has a HOLD button, which in effect is a 0.5 - 1 second sampler ( without editing features). Send a phrase from whatever sound channel you like, ( vocals are cool ) to the delay, and as you do, hit the hold button. You will have to get the timing right, but once you do, the sound will just go around and around and around, repeating like a loop.

Now....go to the DELAY TIME KNOB, and play with the control......If you captured a sound with the delay time at full, then you can only adjust the sound UP.....It will rise up in pitch, until it sounds like Mickey Mouse on acid...You can sweep the sound up and down in pitch....

If you set the delay to a short time, you can capture the sound and use the same control to make it swirl DOWN in pitch....This one sounds the coolest.....By adjusting the DELAY TIME....and the return fader from the delay, you can make the sound swirl around....then rise slowly up in pitch as it eventualy dissapears in volume...
If there are two people available, one can do the sweeps, and the other can pan and adjust the volume....This sounds great....

If you are working alone, and you want to produce multiple FX like the above, but also with pan and volume fades, or complicated echo FX, see the COMPLICATED DELAY FX PRODUCTION TIP down the end of the page !!

YOU CAN GO TO THE DELAY-TABLE... WHERE YOU WILL FIND A LIST OF DELAY TIMES - BPM TIMES, THAT WILL GIVE YOU EXCELLENT CROSS-RHYTHM DELAYS.






MODULATION TIME DELAY

Either type of unit - knobs or cursors - can be used for these FX. Niether type is any better for the job.

Any typical delay unit will have a MODULATION DEPTH Control, that is used to make the delayed signal rise and fall in pitch, and also a MODULATION SPEED Control, to adjust the speed at which it rises and falls in pitch.

These controls allow you to perform Modulation FX such as:

  • CHORUS.......A short delay time of about 100 ms, with minimal Feedback, and a little Mod Depth & Speed.

  • FLANGE.........A very short delay time of about 40ms, with more Feedback, and anything from a medium to large amount of Mod Depth & a low Mod Speed


For a deeper CHORUS, add more Mod Depth and/or increase the Delay Time.

For a deeper FLANGE, add more feedback, and/or Mod Depth.....You can experiment with the Mod Speed.

Just remember.... There are no fixed rules. Check out some of the FX and other Tricks




MODULATION TIME DELAY FX TIPS

THESE FX CAN BE PERFORMED WELL WITH ANY DELAY UNIT


STEREO FLANGE SPREAD

This FX can sound good on anything from a hi-hat, to a bass synth......It`s basically a tight Flange fX, split L & R, to spread the FX`d sound across the speakers.

Set a short Delay Time.....About 50 ms. Then select the hi-hat channel, and send some hi-hat signal out to the Delay Unit via the Aux Send.

Bring the Delay return back into the desk, and Pan the original hi-hat Left, and the Delay hi-hat, Right.......Adjust the Delay time, Feedback, and the Volume level of both the original and Delay hi-hat, until you get a nice metallic hi-hat sound, spread across the speakers in stereo.....

You can now try sweeping the sound, by adding some Modulation Depth, and turning up the Feedback Control.......You can play with the Mod Depth, until the sweeps rise & fall in time with the track.

If you really tighten up the Delay Time, this FX sounds wicked on Bass......If you go real mental with this FX, you will get the old Police Siren Special.....


POLICE SIREN


This FX seems to work better on crappier delay units, cos what we're after here is overload feedback, and some of the more expensive units have something inside to prevent the unit from overloading.....

Basically, just set a short Delay Time and everything as above....Now turn the Feedback Control right up as far as it will go, and increase the level going into the Delay Unit, until you get self oscillation!

At this point the Delay sound coming out should "CATCH".....It's hard to describe, but if the Delay Time is set short enuff, then the sound should sound like a Police Siren....Rising gently up and down in pitch......Like........... WEEEEEEEEOOOOOOOOWWWWW...... WEEEEEEEEOOOOOOOOWWWW.... (Hmmm, bet that makes it clearer !!)

Once you have got the unit feeding back, you don't have to send the Delay into it any more....If you turn off the send from the hi-hat, to the Delay, the sound should stay......

Now you can mix it in with your regular track......You can switch from the long siren sweeps, to short ones (just like a real siren), by adjusting the Modulation Speed or Rate from slow to fast, and back again......

If you get this right, it's indistinguishable, from a real siren..... Exactly the same sound!


SURROUND SOUND/ X-OVER DELAY


There are some units on the market, that will push out the edges of the stereo field, to give more width to the sound.....You can get the same FX by using 2 short delays, and adding this FX to your finished Stereo tracks...(of course you will need 2 Units for this FX).

First, get your Stereo track routed through 2 channels on the desk, panned L & R.

Set each Delay Unit, with a short Delay time, about 20 - 40 ms., with no, or very little Feedback, and no modulation.

Next, send the Left channel to Delay Unit 1, via an Aux send.........Then send the Right channel to Delay Unit 2, via another Aux send...(the Aux sends must be seperate).

Now, Pan the Left channel Delay return RIGHT..............And the Right channel Delay return LEFT

Finally, adjust the volumes of the Original L & R Stereo tracks to be equal, then raise the L & R Delay returns, until you get the desired FX strength.....This FX can sound great if you gring it in applied quite heavily at a breakdown point on the track.


STEREO CHORUS SPREAD FX


This FX sounds great on synth lines, and can make it sound like there's a doubled layered sound.

Just set up the Delay Unit for a standard Chorus sound...That is a low Delay Time about 100ms, about 20% Feedback, and about 25% Mod Depth, and 50%Mod Rate.

Just pan the original synth Left, and the Delay return Right, for a nice fat stereo spread sound....

This also sounds wicked on backing vocal harmonies, spreading them right across the Stereo field, and seperating them from the main vocal.... It can also helps to hide dodgy tuning, if your vocalists are a bit flat or out of tune.

YOU CAN GO TO THE... DELAY-TABLE... WHERE YOU WILL FIND A LIST OF DELAY TIMES - BPM TIMES, THAT WILL GIVE YOU EXCELLENT CROSS-RHYTHM DELAYS, TO PICK UP YOUR TRACKS.






COMPLEXED DELAYS FX

THESE FX CAN BE PERFORMED WELL WITH ANY DELAY UNIT


Sometimes it's a nightmare getting the echo FX right at different places on a chewn.....there is a solution...it`s pretty obvious, but it took me a while to figure it out.....

You can do this with a multitrack like a Fostex, or better still with Hard Disk.....If you have visited this site, and your are unfamiliar with Hard Disk recording, or are thinking about it....then check it....If you are wanting to get into dance music.... House.... Garage.... Hip-hop.... R&B..... especially any dance chewns that have a vocal, (but that is about all the audio recording you will need), then I would definately recommend Hard Disk (H/D).....as it's perfect for this type of thing !

Anyway.... it's simple really..... If you have a multitrack, and a sequencer which you are using to do your MIDI stuff, then if you don't have them synced up, get it done....


Don't bother with SMPTE code.....just get a cheap MTC ( Midi Time Code ) box, and sync up the sequencer so as it's chasing the tape......


Rehearse your echo F-ect, then route the echo to a track on the tape, and tape the F-ect......try a few passes until you get it right, then just set the level for the tape track return and mix it in..... Hey-Presto.....a perfect F-ect every time.....

Another great thing about this system is that you can buy one cheap delay, and tape the first F-ect, then reset the delay and utilise it for either another delay time F-ect, or as a chorus, flanger etc......

If you are getting H/D, or have it, with either the H/D programme clocked to the sequencer, or regions assigned to MIDI note numbers, or....you have a programme like Cakewalk Pro Audio, Cubase with audio or Logi Audio etc.....try this....

Setup the delay F-ect, run it, and tape it to DAT, or direct to the H/Disk.....If you put it on DAT, just copy the passes over to the hard disk.....and line them up....or even try moving them around to create new cross-rhythms....

If you have a machine capable of playing MIDI in time and recording audio simultaneously, just record into the PC and play back....of course, you can also try offsetting the F-ect to get different cross-rhythms......

By the way....You can also do this with reverb FX as well....!!

hi
I got a qestion:
I turned up the aux send from the output of the delay unit into a mixer track, so I can send it TO the delay again, to create FEEDBACK; but I hear some noisy hiss even if the volume of all tracks is cut to zero. It's because the delay unit isn't a good one?

Thanks.

I want info about tape delay, I already know the basics but I want info about tape record/play heads, erase heads, motors, (as in, how to wire them all together and make a working tape recoder/player

Question relating to drum effects..

Hi, im into producing bassline & speed garage. Historically i have used drumloops but more recently i have made my own. However when i view the wave form and compare a drumloop say from a sample library to a drumloop created by myself, i see that my hats and snares sit perfectlly on the zero crossing whereas the sample library drumloop hats and snare appear to pan around the zero crossing. How can i produce this effect?

Cheers

Wayne
