Hi, I'm having some trouble with this patch I'm making for an installation.

what should be happening

there are 4 zones, each with 2 microphones and 2 speakers. when moving through the zones your audio is recorded and played back the next zone like this

enter zone 1
record mic 1 + 2

enter zone 2
record mic 3+4
playback recording from 1+2 over speaker 3+4

enter zone 3
record mic 4+5
playback recording from 3+4 over speaker 5+6


the recording is going more or less fine but no sound is being played back..
could anyone take a look at this patch ( you need audio card with 8in and 8out to test) and tell me what I'm doing wrong? maybe not waiting long enough before playing back the recorded files?
