Closed Tera Echo Delay

[Fat Biscuit]

I got my FM3+FC6 about a week ago and have been having a lot of fun playing with it so far. I have a Boss DD-500 that has a Tera Echo mode that I love. I'm not exactly sure what Boss does to make that specific effect, as it is kind of unique (to me anyways). My wish is to create a similar effect with the FM3. If this is already possible, can anyone tell me how they did it?

Update.
I tried messing with mixing the delay block with trem, filter, and reverb blocks but couldn't get close to the tera echo. I decided to just add the dd500 to the board, but I couldn't easily press its switches since they're lower in height than the fc6 and fm3. Then I realized the dd500 has midi, so I can use the fm3 to turn it on and off by scene. Problem solved for now.
Still want a tera echo mode though...
