Korg M1R Battery Replacement
Gee, my last post was another DIY article. I can almost copy and paste this. :) But the subject is entirely different.
I've just posted a new article in the Articles section, describing how to replace the internal battery on a Korg M1R synthesizer module. When the battery dies, the synth is dead and you lose all the internal program memory. Your only recourse is to open it up, replace the battery, and then locate and restore the factory programs or your custom programs. Fortunately, it's pretty easy.
