I've been listening with interest to the threads regarding real-time 
control and the problem of intuition while working with CSound and 
we seem to be thinking along the same lines.      I would like to see 
CSound become far more intuitive,   hence Visual Orchestra,   but I 
have experimented over the last few days with MIDI control of 
parameters using CSound command MIDICTRL.   It seems to me that a 
virtual MIDI synth interface is what is needed,     I've not seen 
Cakewalks studioware feature but I suppose it to be similar to 
Cubase's realtime MIDI controllers,   OK but not ideally suited to 
CSound control.

	What about a MIDI controller designer (This could 
be incorporated into VisOrc or be run seperately) where the user can 
design and save sets of buttons and sliders with assignable MIDI 
functions?      I'd make a start but CSound crashes with even the 
simplest MIDI control messages.

This bug has arisen through incomplete communication from myself to John
Fitch, regarding Microsoft-specific symbol definitions for the open()
function.Unless an additional parameter  is used, in addition to all the
usual ones, a file is created read-only.

For those with the sources, and the means to compile them, a change must be
made in filopen.c, in the section where the #defines for the fcntl options
are made:

replace the lines:

...
#if defined(__MWERKS) || defined(SYMANTEC) || defined(_WIN32)
#define RD_OPTS  O_RDONLY | O_BINARY
#define WR_OPTS  O_TRUNC | O_CREAT | O_WRONLY | O_BINARY
#elif defined DOSGCC
....

with:

#if defined(__MWERKS) || defined(SYMANTEC)
#define RD_OPTS  O_RDONLY | O_BINARY
#define WR_OPTS  O_TRUNC | O_CREAT | O_WRONLY | O_BINARY
#elif defined _WIN32
#define RD_OPTS  O_RDONLY | O_BINARY
#define WR_OPTS  O_TRUNC | O_CREAT | O_WRONLY | O_BINARY,_S_IWRITE
#elif defined DOSGCC
...

and normal service will instantly be restored.

I think John is planning a further update shortly. In the meantime, the
fairly painless hack within a DOS box use to use the ATTRIB command:

attrib -r myfile.wav

I think you have almost precisely described Cakewalk studioware features 
mensioned above. Cubase has probably even more powerful mixermap feature - 
not just realtime midi controller, but customizable set of control elements 
to send continous midi messages.

Hi
To  join IRCAM forums in oder to use the software one has to register wit=
h the
various groups,ie Algorithmic composition, signal processing, and real ti=
me.
The cost is approx =A3350- 00 for three groups I believe, theiir is also =
a
University price as well . You need to contact IRCAM and  they will send =
you a
form .I hope this is of some use.
