Nice post, Brock.

Just to add a little to it… The Filter Pong Algorithm on the H9 and TimeFactor is a series delay.  Delay A feeds Delay B.

This is a little known Eventide “Easter Egg”, so to speak!  Check it out if you have the chance.

Thank you for that info. I never tried it because I assumed I had to have this hooked up in stereo to use ping pong mode. So if I put it in ping pong mode but only use 1 in and 1 out, it will be a series delay? 

Brock, while I did not use your exact numbers, I did pick two long delay times that were separated by the golden ratio. I dialed a fair amount of feedback and added some low pass. This is whatI was looking for!

Thank you both again for taking the time to post.
