Okay, so I'm only a veteran of MIDI as far as setting up 90's computer games and tinkering with the occasional sf2 file in VirtualMIDI on my Win10 machine, and I recently reacquired my Casio CTK-631 keyboard from childhood, ca. 1999, so I think it's only GM1. I got it back from my mother simply to use the keyboard as an input device, and I have a friend who has expressed interest in MIDI. Anyway, I discovered I can save "SysEx Bulk Data" on my PC. Neat. What does this do for me?
What little I can find online says something about using it to transfer sound data between MIDI devices, so naturally I'm thinking, Better sounds? Obviously, there would be some sampling limitations or something, but I think I'm getting ahead of myself. Now that I have an idea of what bulk data is, my main question is, quite simply, what can I do with Bulk Data?
