multi-part piece: output for separate parts

[benoit farley]

Hello,

 

I have a piece of music for 4 harps, and I would like to know how to produce outputs

for each separate part: one output set of files (pdf, ps, etc.) for Harp 1,

another set for Harp2, etc.  I could do it by commenting out all but one

part, but each time, I had to make sure to rename the output files, otherwise

I would loose them at the next turn. (I'm using jEdit)

 

Is there a better way to do this?  On the command line, maybe?

 

Thanks,

 

Benoit Farley
