Hi everyone!

I'm trying to make sense of the MIDI implementation document for my Volca FM and I'm getting nowhere. I have no previous experience with SysEx and I can't understand how to read the tables. I want to program sliders on my MIDI controller to control operator output level. Can someone take a look at this and give me a few pointers?

KORG volca fm MIDI Implementation Revision 1.01 (2016.4.07)
