I created a simple melody using a piano and added a ping pong delay.

Does anyone know if its possible to isolate a particular sound from this loop? Basically the sound that comes from the ping pong delay I would like but not the simple piano sound? I have attacked how it sounds so you can better get an understanding of it.

 

Set the mix on the delay to 100% wet and you will get only the delay sound with no dry signal. 100% effected sound.

 

well that depends on what delay u use, does it has a dry wet knob? maybe you could reproduce it in twindelay Freeware

 

Let's assume he's using live's built in ping-pong delay.
As delays etc belong into send channels, you have to hit the pre/post button on the particular send so you can mute the piano channel and still be able to hear the effect.
