Xrnitool.py


(frl) #1

Here’s a small Python script I wrote to do some chores for me on large multisample xrni’s, you can easily change all the sample volume’s, the newnote actions and the panning of all samples in one instrument at once. Very easy to expand on as well.

Just drop this and 7zip in your path and run it from the command line, it’s pretty basic since it’s my first ever python script. I’m not sure if this will work on the new 3.0 version.

I love this!! Is there any way to have this also turn the Volume envelopes off or on (really, just off)? I tried to figure it out looking at the code, but I’m not a programmer…

I’ve made some changes to the code to turn off the volume envelopes (for those who want this).

Here’s my revision of xrnitool.py:
