Reply to Midi Fighter Help! How to use Echo!

Hey DJTT,
just got my mf pro (beatmasher) and love it. One problem im having is with the echo feature. I understand the concept of delaying out then echo freezing it but i have found that i can only successfully do it one out of every five tries. Is it a timing thing that I am missing? or is there some other trick?

Thanks
-Brent
