As a first step in creating .sfz files for organs, the java source
included below will create .sfz files for simple cases. It assumes that
the directory structures and .wav file names are as normally defined for
grand orgue dispositions. It will allow multiple attack samples,
separate release samples, or just a release decay as has been common to
this point in Jorgan dispositions. It will allow one sample per note
.sfz files, or regions in which one sample is spread over several notes.
for such regions a separate text file is used as input defining the
region boundaries and the root note pitch. feel free to copy and
improve on this tool, which includes limited documentation embedded in
the source file. Subsequent posts will illustrate generated .sfz file
examples.
Usage:
paste the source below into a text editor and save as
Sfzfilebuilder.java. On a computer with the java SE SDK installed,
execute the command:
javac Sfzfilebuilder.java.
this will create a file Sfzfilebuilder.class. Copy this to your
working directory where you want the .sfz files created. from a
terminal window in that directory execute the command
java Sfzfilebuilder
you will be asked a series of questions that will define your .sfz file,
and the resulting file will be created.
