Notice that I said it was "hard". Whats hard is that you are now using
two different internal data sources for audio output: the internal
start-of-loop cache, and the regular streaming data flow. "Hard" for
me doesn't mean "can't be done", it means "messes up a nice, clean s/w
design with ugly details that can easily go wrong in a real world
application".
Building a stomp-box thing that worked like a Jamman is really
extremely easy (I wrote 80% of one just using Quasimodo). Doing this
inside a multichannel HDR system is quite a bit harder. Doing this in
a system where the data stream comes from an EDL is probably an order
of magnitude harder still. Perhaps, anyway.
