[chuck-users] --silent does not synchronise

Hi Eduard and all,

Sorry for the mailing spam silence.  We have been away at ICMC and I am 
going back under the radar for a few more days (will return to 
Princeton early next week).  Eduard, it's very good meeting you in

The --silent flag actually means "no real-time audio.  compute samples 
as fast as possible", and is a way to do "offline" synthesis 
(generating to file).  That is why time can move much "faster" under 
this mode.

At the moment, there is no easy way to synchronize two separate ChucK 
virtual machines.  It is possible to use dracula features to pass OSC 
messages to/from the virtual machines, which may be one low-latency 
approach to do what you want.  (see examples/event/opensound_demo_*)
