Kawai SX-240 with full MIDI CC!

Published on Mar 25, 2017 Sean Ober

"Thanks to the fine folks at, this minty Kawai SX-240 now responds to MIDI CC. Burned a couple new firmware EPROMs, removed about 8 screws, swapped the chips and done! Such an easy, rewarding mod.

Early stages of this available firmware but damn-near complete... hat's off to This is one of only a few SX-240's in the world, this powerful ;o) Shoot, only about 1000 of these boards might have been made and many, many of those died due to battery leaks. Talk about a rare bird.

I also would like to thank Jordan from Cuff Lynx for selling me this bad boy! Thanks and Save The Wave... SynthWave that is!!!"
