hmm that works in a simple case, but what about if you actually want the
noise gate to function properly and not fire on each channel, instead
acting on the whole chane? Now you have to have two of these such monitor
chanes, one for each channel. It's quite wierd and if you have a look at
my former post of my ecasound setup file it could get quite lengthy if I
decide to really play with this. I'm also worried about latency and don't
really want to deal with adding MORE loop devices, I feel 3 levels of
indirection is enough! :)
