Hello All,

I was wondering if any users could point me to any program that 
converts Csound SCORE data into standard MIDI format ?

The idea being simply to generate musical notation with a Csound score 
as input ? MIDI is merely a device for this and is not necessary if 
there exists such a program that converts directly Csound score to 
music notation. MIDI seems more flexible though ...

Any hints / tips / pointers on this idea are greatly appreciated!

CSound scores typically contain more information than MIDI files, so I think
a direct translation would be difficult in many cases.  If your score
follows some very specific rules, you may be able to use an AWK or Perl
script to translate it into an intermediate text format, and then translate
to MIDI from there.  Is anyone aware of a tool that specifically converts a
text file to MIDI only?  I have experimented with LilyPond, which is capable
of generating sheet music and MIDI from the same source text file.  If you
just want a text file to MIDI conversion, give LilyPond a try.  I think some
kind of link between these tools would be great, but it would probably be a
LilyPond to CSound translation, rather than the reverse.

Disclaimer: I am not a highly experienced user of either of these tools, but
I have had some exposure to both of them, and have reproduced a few sheet
music scores in LilyPond with some success.

Thank you for all of your suggestions.

I wish the link that Kanata posted had the source code available !

I have checked out Midge and LilyPond and both seem to appear to do the 
job as well, but with some more work involved.

IMHO, this idea of Score to MIDI or vice-versa has taken on a much 
larger significance than in previous versions with Csound5 because of 
the addition of Format 1 support.

In the long term I will try and write a wrapper per Steven's 
suggestion. I can see there is clearly a need for it and I could 
undoubtedly learn much from attempting such an exercise.

For this I use Istvan Varga's commandline ScoreProc suite. It can be 
found at his cSounds.com site 
http://www.csounds.com/istvan/html/scoreproc.html

Although there are also several others that you may find for various 
platform specific solutions on the Utilities page at 
http://csounds.com/utilities

Incidentally, you do not even need a third party application to convert 
MIDI to Csound score. Here is a Csound file that was made by a leading 
Csound developer, Istvan Varga. With some modifications I have found 
this tool to be of great usefulness, and use it regularly when I am not 
using the commandline 'mid2sco' by the same author.

I'd like add that two command-line utilities, readmidi and writemidi, will
convert MIDI->score and score->MIDI.  They can be obtained from:
http://ems.music.utexas.edu/dwnld/rwmidi.zip
The binaries are for Windows, but source code is provided.  I believe readmidi
works with format 1.

John,

This is excellent ! It uses only standard ANSI "C" header files and 
compiles easily using just gcc on OSX and Linux !

What license is this under ? It does not have any indication within the 
source itself and I really think this utility should in some way be on 
cSounds.com or possibly merged with the CVS source tree ... since it is 
just two ANSI "C" compatible *.c files.

Hi David:

  Don't forget about Common Music ! You can generate your Csound score 
and MIDI file at the same time. :)

  There may be a way to import a Csound score into CM. From there to 
MIDI is a simple step.

Best,

dp

I have had the same problem in the past using a different Midi to Score
program.  I agree that it would be nice if there were some simple opcodes
like cpspch to convert midi note numbers to cps, pch, and oct formats.

I good route to go for now might be to write some macros or user-defined
opcodes for the task.

Here is a macro that converts Midi notenum to cps, I think (from Dr. B or
David Akbari, not sure who):

#define MIDI2CPS(xmidi) # (440.0*exp(log(2.0)*(($xmidi)-69.0)/12.0)) #

This might be better like this:

#define MIDI2CPS(xmidi) # (cpsoct((($xmidi)+36.0)/12.0)) #

And to get octave-pitchclass notation:

#define MIDI2PCH(xmidi) # (pchoct((($xmidi)+36.0)/12.0)) #

I hope these are correct.  (Someone will correct me if they are not :)
