Stereo Delay vs Ping Pong Delay

[drbob1]

Digital delays allow you to do all sorts of evil things to your sound, and they're set up in all sorts of different ways. Most modern digital delays have two inputs and at least two outputs, so you can do:

Mono input, split to two signals each with its own delay engine and blend of dry/wet, possibly mixed back together before output.

Dual input, mixed, delayed and output

Dual input, kept separate with separate processing

Technically a ping-pong delay would be a special case of type one, with a single delay engine, and an LFO driving the panning of the output signal.

If you really want to blow your mind, a couple of interesting devices include the Akai Headrush which has 5 outputs that it sends the signal to, sequentially for a ping-ping-ping-ping-pong kind of thing. And the Yamaha UD Stomp that includes 8 separate delay engines that can be set up in parallel or daisy chained in any combination then output to stereo for very complex ping-pong effects.

Technically A straight ping pong delay is just A left/right ping pong ball bouncing back and forth across the stereo field. A Stereo delay can drop the resamples all over the stereo field. Typically in time with the music by tapping the tempo key in time with the music A few times on A hardware unit. Or using the tempo setting in A Daw.
It can then be gently faded in usually in A multitap mode dropping decaying samples all over randomly. Setable from A single sample to many all over the place. I have never used A simple ping pong in A song myself. But is fun to play with.

And lets not forget the shorter delays become doubling. Even shorter (Using the width and speed control) are chorus. Even shorter is the phase shifter. All one box and all cool stuff.

even shorter is the Haas effect right but only if the delayed side doesnt have any dry signal right? Like 2 tracks are duplicated and panned left and right. Then you physically move one side by 1-5ms. I guess you dont need a dealy unit for this and I dont really know an application to do this with but just thought it relates

Thank.

Couple more questions.

1. Do you only need stereo delay when you intend on having diffent delay values for L and R sides?Is this is what is needed for an widening effect or can you get this widening effect with the same delay values on L and R?

2. Say I have a stereo Synth like an OB-XA that I want to put a mono tape delay effect on like dub music or reggae.In this case being that the left and right side would be the same timing values(typically 8th note) having a mono or stereo unit would result in the same sound,right?

If you're using a stereo delay with the same delay times you could still make other parameters different from left to right, like differing feedback levels or eq-ing the returns differently.
