jMusic - Composition in Java

Hi!

The CVS repository on Sourceforge.net is not accessible!

I get this error:

> Proxy Error
> The proxy server received an invalid response from an upstream server.
> The proxy server could not handle the request GET /viewcvs.py/jmusic.

cheers,

Hi!

I am currently working on an interactive computerbased composition 
environment. It will comprise different approaches of analysis, recombination 
and algorithms and is mainly based on David Cope's EMI.

I decided to use jMusic as basis. However, a working CPN is crucial for my 
project, so can you please tell me the current state of the CPN. Which parts 
still need work? Possibly, I can participate in the development. 

Thanks,
	Andy

Hi James,
could you please make a test class so that I can run it and verify the error.
Cheers,
Rene

In MIDI terms, the duration parameter within the note class determines the 
interval between the note on message and the note off message, in beats.

If you want the note to sustain until the next note starts, simply make the 
duration equal to the rhythm value, because when it is initialised, it is 
actually slightly less

in this example
>Note n = new Note(C4, CROTCHET, MF, PAN_CENTRE, CROTCHET * LEGATO);
if legato = 1.0, nothing will change.
if you want the note duration to be twice as long, for example, make LEGATO 
= 2.0;

Cheers,
Rene

I have a question, I want to have a seres of notes that are slurred,
as legato articulation. Looking at the documentation,
http://jmusic.ci.qut.edu.au/jmtutorial/Constants.html
it gives me the code snip of:

Note n =3D new Note(C4, CROTCHET, MF, PAN_CENTRE, CROTCHET * LEGATO);

This does not work.. nor can i find else where in the documentation on
how to do this.

hello,
are there very many people on this list?
i have been learning jmusic through the documentation for a few weeks.  
i am working on a school project, so there is a rather pressing time 
cosntraint.  i have a file that creates four different parts, and then 
tries to write each one to a separate .au file, by calling Write four 
times, thusly:

			Write.au(phr1, "acoustics/Part1.au", inst);
			Write.au(phr2, "acoustics/Part2.au", inst);
			Write.au(phr3, "acoustics/Part3.au", inst);
			Write.au(phr4, "acoustics/Part4.au", inst);

however, the first call to Write succeeds; all subsequent calls produce 
the following exception:

java.io.FileNotFoundException: jmusic.tmp (No such file or directory)
         at java.io.FileInputStream.open(Native Method)
         at java.io.FileInputStream.<init>(FileInputStream.java:106)
         at jm.audio.Audio.addEmUp(Audio.java:337)
         at jm.audio.Audio.combine(Audio.java:169)
         at jm.util.Write.au(Write.java:361)
         at jm.util.Write.au(Write.java:442)
         at acoustics.GoldenSection.main(GoldenSection.java:138)
java.io.FileNotFoundException: jmusic.tmp (No such file or directory)

can anyone tell me why?

the four parts all go together and are synchronised in time, but i want 
to get them in separate files so i then can import them into a sound 
editor for further manipulation.

thanks a lot,
-k
