Well, I can now load my giant heavy gig ensemble into the fl_controller 
example and play no problems, awesome! I don't need to put the 
-+rtaudio=alsa in my rc file anymore either, and it works fine with 
--sched on twiddling the fltk knobs.

However, something strange I noticed while experimenting on this. When I 
use the following line from the command line:

csound -+rtaudio=alsa -o dac -b512 -B1024 -m0 -d -M1 --expression-opt 
--sched -Lstdin flow01.orc flow01.sco

I can do anything I want without any hiccups. I can resize and open 
windows, whatever. When the exact same line and code is used wrapped up 
in a .csd file, this is no longer true, with or without using the api 
front end ( ie "csound flow01.csd" ). It's still solid for playing with 
the fltk knobs or looking at top, but it clicks when I open or resize 
windows or use the fluxbox pop up menus. I assume this is a problem 
somewhere? If not, is it possible to use the api without using a .csd?

Thanks
Iain

The --sched option has effect only if it is used directly from
the command line, and it is also only implemented in the standard
command line frontend. In any other case, --sched will be ignored.

Thanks Istvan? Is that mentioned in the manual yet or is that something 
that is planned to be changed?

Is there a way to use --sched with the API? If not, could there be? I 
tried recompile the fl_controller example replacing "csound" with 
"csound --sched" in the string that is passed to CsoundCompile() but 
that didn't seem to have any affect.

At any rate, considering that using the API in a host app means the user 
is very likely to be doing things like switching windows, IMHO the 
--sched improvement is much needed somehow or another.

Thanks
Iain

It was this way for a long time (well, since --sched was added),
but may be changed eventually. As a temporary solution, you may
try adding the --sched code to the fl_controller example itself;
it is in frontends/csound/csound_main.c.

Ok, I will try that. I do think that would be a great thing to add to 
the api however, as it seems to that one is quite likely to do the sort 
of things that make it break up if using a graphic host.
