Since the beginning this site tryes to be a compilation center of the best sources for the JD800. Not a copy.
So please, visit the sites at the Links section for lots of much more very good information.
Few notes:
You need to free your computer midi ports on which the JD is connected for CTRLR and assign them to CTRLR in the global settings. Download the panel (it's currently at the bottom of the device database). Once open from CTRLR, right-click on the panel and assign the midi device to the panel.

Pay atention to details and you will be surprised. I comment only a few. Well, he removed the damaged keybed. here in the blog you will see another modification such like this. The headphones output in front make it easier. Thejoystickwas placed apart andit is onatemporary support.
The plastic over the card place is a great idea. Protect against contact with the flat cable and prevent also agaist dust.
I say dust? Oh my god! He made a total cleanup! Dust inside is the great problem of the JDs. Anothergreat ideawas to improveheat dissipation in the power source. The connectors are no longer soldiers which greatly facilitates maintenance.
Love to see all that. Thanks Efrem, our congratulations!
