Hi, I think this may be useful for someone. Today I built a Google Colab notebook when I needed to adjust volumes of my projects for the same certain value, because I noticed that they are clipping when routed through dedicated outputs. This python script expects one xml file or a zip file with multiple xml files and then changes gain of all pads in the projects.
This also can be useful for balancing volumes between projects. For me manual changing each volume in the mixer of every project is too tedious.
If you have any ideas what other useful features could be added you are welcome to collaborate, I think, together we could create a notebook with frienldy user-interface and rich functionality. What comes to my mind, for example, is shifting notes in all or selected sequencers for a certain number steps.
