Something I've been doing from pd: writing a line (or more) of text to a fifo and letting csound read that in as score lines.
Trying the same from chuck -- I find that I can write text to a normal file. When I send the same text to a fifo, nothing happens. If I don't close the fifo chuck merely freezes; if I do close it at the end of each line, chuck continues to receive midi notes but csound doesn't get anything from the other end.
Do I need to open the fifo in 'WRITE_ONLY mode"? Will try now.
