An octave would be way too much.
It's hard to hear, but maybe the sample is just two tones, then you don't need the pitching. I guess it's a very simple pingpong delay with lots of reverb.
I'm not familiar with H-delay.
How can you tell it's a ping pong delay?
And I mean, obviously I know it's a delay and a reverb. I've been producing for a few years so i'm not completely clueless. That's just not the answer i'm looking for at this stage and I don't mean to say that to be a dick, I appreciate the help as you are the only one who has responded. I need more specifics.
What pingpong delay? Is there a high feedback? Does having a higher feedback cause the delay to repeat/last longer? Is the delay automated? Is there a gate on the delay?What kind of reverb/room? Is this kind of effect better achieved by using delay and reverb sends or having the delay/reverb on the actual track channel? I usually always bus my delay and reverbs but obviously when you use them as a send they are not as powerful/accentuated.
