Can you say more about UDP patches that have been posted? I did a search=20
for this and came up dry. Does this capability exist natively in=20
Csound5? Is this UDP full duplex or send-to-Csound only (as -L stdin is)?

<pre wrap="">There are 2 options to running csound in parallel:
1. Networked CSound
Send CSound UDP messages etc using patches that have
been previously posted, or use netcat and -L stdin . Then you send your
score events out to various CSounds and remultiplex the audio later.
2. Split your score up
If you have a long score, simply split it up based on
many computers you have leave a few overlap notes to deal with long
running instruments. Recombine later.
CSound is single threaded (unless you use the GUI). Marsys might
be usable in parallel now but I'm not sure if that code is released,
they have UDP and TCP sources and sinks.
