https://drive.google.com/file/d/1GFb1scp7By7wojnKft_1MlFEg29ace3d/view?usp=sharingMy first attempt at this, I apologize in advance for everything that might go wrong.
Made partially by editing/reusing instrument definition file for SX700 from

I would like to give more descriptive names to banks than e.g. "Bank 20", but all of the banks seem to contain various, dissimilar instruments; and giving them all names like "Bank 20 Various Instruments" doesn't seem any more useful. Please let me know if there is a way to improve this.
