[Question] Help with ripping music required

Hoi, Glitch here. So, I've been looking for a music pack that has all the music from black and white (2) and a fully compatible sound-font. I've been looking for days on without any result. Thus, I have decided to make it myself. However, I lack any, if not all knowledge on ripping and recomposing midi files with their respective sound-font. My last attempt, the midi-files came out perfectly, but the sound-font was spliced into unique font files for the intstrument category. Which meant that if I where to use one of these sound-fonts with one of the midi-files. For instance one labled as bass, only the bass would play. My question:

Can anyone provide me with a toturial, guide, or offer to think alongside me for ideas and work this out?

I already have the required files ripped from a copy of Pokemon Black Version, the DSi enhanced one. (I was a bit late to join Gen 5 😅)

Thanks in advance!
