Dream Theater - Overture 1928 (keyboard tutorial on Korg Kronos) performed by Junghwan Kim

This video doesn't explain how to make up all sounds for the song, but you can listen each patch and follow up with your own keyboard in your studio.
Try to make your sound patches similar to the original song or mine.
Making sound patches is also needed practice like finger practice.
Besides, I referred JR's live, but I didn't follow all he did.
I used the original keyboard track from Jammit and made my patches to play easily.
