Reverb building with comb and allpass filters

Rokitpower's icon

Hello there,
I'm kind of new to max trying to build a simple Schroeder reverb. I've linked up some comb and all pass filters and followed the Schroeder schematic but it doesn't seem to produce any reverb. Would anyone be able to help me out/tell me what I am doing wrong?
