Dear list, 

 is there a way to suppress the echo of typed characters when running csound in "old school" terminal mode? I often use the sensekey opcode, but the keyboard echo mixes up with regular screen output. 
Using the -d and/or -m0 options does not stop it.

Best,
Jana

I don't know about a Csound option, but depending on your operating system
it may be possible to change the echo setting with a separate command
before running Csound.  On my Linux installation,
   stty -echo
turns off echo and
   stty echo
turns it back on.

This might fail if Csound is explicitly turning on the echo setting
itself, but I doubt that it would; it is more likely completely blind to
terminal settings.

If I were doing this a lot, I might write a shell script to automatically
run these commands before and after running Csound.

Hi Matthew,

yes, that did the trick - exactly what I wanted. Thank you so much! Never heard of the stty command, though I'm on Ubuntu.

For more covenience, I put the whole thing into a shell script, to re-enable the echo after csound terminates and stopping the blind flight afterwards. Works like a charm :-)

Best,
Jana
