I acquired a Yamaha PSR-280. It came with audio issues that I temporarily fixed but it then returned. I found out that It was a hardware flaw. Some chip kept loosening or something. This is when I got the bright idea of extracting the instruments and making a SoundFont off of it. The problem is, there are absolutely NO GUIDES for this. I know, I know If I want to do this I should probably make my own program or mod it physically.
1.) I literally don't know how to code
2.) There isn't really that much documentation on it
I wanted to consult StackExchange before giving up. Does anyone have a copy of the instruments or know how to extract them?
