Schroeder reverb, but no signal through sub patcher

Hi, I'm trying to implement the Schroeder reverb algorithm in Max as an exercise, but I can't seem to get the signal to flow through the patcher. What am I missing? Is the attributes being set on load and that's the reason the patch doesn't work? I'm a beginner in Max/MSP so my problem might very well have a basic solution that I don't see.

You can hover your cursor over any wire passing audio signal, and see the waveform. This should help with troubleshooting. The problem seems to occur somewhere in the second [p allPass] subpatch.
