yes, I think -+rtmidi=NULL -M0. Rory Walsh used
this in something he was doing last month, perhaps he
can tell us more.

By the way, can we move these discussions to the
Csound-devel list? I am a little bit conscious of
users being turned off this list with all this
code-talk.

Ya - it does seem to work (so far).  The way I was passing arguments  
through the API was the problem.  Each argument must be a separate  
index in the argv array .. should have known I couldn't combine  
them .. anyway - sure, sorry about posting this in the main list ..  
I'll post the API questions on the dev list.

thanks

Hi Greg. So you did get it working in the end? I was trying to do this 
some weeks ago as Victor mentioned and I found the best source files to 
look through were Steven fltk keyboard sources and Mike CsoundVST 
sources. They both provide good examples of how to pass MIDI from a host 
to an instance of Csound. Good luck.

Rory.

Yes.  It is working quite well so far.  Very easy to use.  As I've  
said before, the API overall is quite well thought out and easy  
enough to use.  It might, however, benefit from further documentation  
to handle the special cases like this one where the API alone is not  
enough to get the answer.

My problem was with the command line arguments.  Perhaps there should  
be API calls to set every command line argument.  This way, one would  
not need to use the command line arguments at all if they're not  
running from the command line.  Just a thought.
