Re: [chuck-users] writing to fifo from chuck

Okay, so inside 'file.ck' a line like: chout <= 1 <= bar <= "i3 0 0.5 60 5 5 \ni3 1 0.5 60 5 7 \n" ; sends two notes through the fifo. Okay, I'm not entirely sure about usage for 'chout' -- but it works! On Thu, Sep 24, 2015 at 12:25 PM, Forrest Curo wrote:

"chuck file.ck > myfifo.fifo " ? Okay, I can try that when I get home; thanks!

{Does this represent an awful waste of sound-processing resources? -- or a reasonable combination of csound rendering methods with chuck straightforward programming syntax?]

Hi Forrest,

If you're only using one fifo and you're not using chuck's stdout for other purposes, you can redirect it to the fifo and communicate that way, e.g.

chuck file.ck > myfifo.fifo

ChucK's diagnostics go to stderr, as does <<< >>> printing, so only stuff you write to chout will go to the fifo.

Basically, to use OSC protocol I end up needing a finicky listening routine in the csound program, with all sorts of complications about starting & stopping notes from the messages... while the -L command line option lets me feed lines directly through the operating system into the score, with csound handling the subsequent timing automatically. So it depends what you mean by 'easier.'

Chuck does seems like a pretty heavy-duty program to use as a midi-timer; last night I worked out a short python script that seems to do the job; but chuck -- if it had the right file-handling capabilities -- is more specifically designed for coordinating a musical process, and might work better. I dunno.

Hi Forrest,

Maybe a naive question: but is there any reason you don’t want to use OSC protocol for communicating between ChucK and CSound ? I think that’s the easier route.

Best, Casper

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.
