I fixed a broken Korg M1 that was left out for garbage
Watch the whole video before following what I do. This video includes some obstacles I had along the way.
I'll eventually upload a short demo video of me playing this, but I'm really not a good keyboardist and I'm certainly not a keyboard technician. I'm an IT professional nerd, so I didn't really feel that intimidated by cracking open this M1 and playing around. I'm also a drummer/composer :)
I want to open this back up some day to clean it more, but at least it works! I can't believe I rescued it from a dumpster. Insane.
