[chuck-users] writing to fifo from chuck

Sat Sep 26 13:51:23 EDT 2015

Hey Forrest,

All the make commands should be run from the top level directory.

You'll also need to need to have Csound installed, preferably compiled from
source to get the Csound API in the right places.

Email me off-list if you need more help.
