Hi list,

I'm having a problem using the -L option to read score events from stdin 
in realtime. When I type, the characters don't appear in the console 
window - only later when CSound exits, do the things I typed suddenly 
burst through to the command line all at once (to be rejected by the 
shell as invalid commands).

I'm effectively a newbie (used CSound before but years ago) so maybe I'm 
missing something simple.

I'm on Windows XP, with CSound 5.11 float. My command line is:

csound -L stdin -d -o dac test5.csd

test5.csd is a simple test score which just plays 3 short notes and also 
has a "f 0 36000" in it to stop CSound from exiting. I hear the notes 
play, and the lines showing time, duration, etc appear in the console 
for those notes. After that is when I try to type and it doesn't take 
the input (I also tried typing a fully-formed i statement blindly and 
pressing return but it doesn't trigger a sound).

I'm pasting the CSound output and the actual CSD at the end of this 
message. Anyone have an idea?

Daniel

This is a known issue with Windows and pipes; essentially, -L and
stdin is not usable on Windows.

Ah, okay. Thanks.

I'm not sure if this would work, but perhaps you could install cygwin.
It's what I used for years when I was still using windows, but needed
a decent bash style command prompt.

Best,

I have Cygwin installed already, so I tried it now but unfortunately it 
does the same thing. I also tried with some alternative terminals (rxvt, 
mintty) and they did behave slightly differently, but still failed 
overall. Good idea though; maybe if I compiled CSound under Cygwin it 
might work, though I'm sure that could turn out to be quite complicated 
in its own right.

Fortunately as an alternative I can try to use the API as this is for a 
program that I'm writing; and using the API was my ultimate intention 
anyway, I just wanted stdin as a short-term test.

Daniel
