WOW! This thing is unreal guys.. No joke.., you'd crap yourself if you saw how much this music app can do.

Off the top..., even though this is a music app for the Nintendo DS "THIS IS NOT A GAME". Too many people see this thing and assume it's some bull&$^$ "everyone can be a star" type game such as "Guitar Hero". The Korg DS-10 "IS NOT" like ANY other music based application for the DS game system. The DS-10 is designed for MUSICIAN'S... You need to understand how a synth operates (at the very least know the basics of patch editing) to really use this thing. You also need to understand the basics of a "step sequencer"...

Worth EVERY penny guys. EVERYTHING is editable on this thing. I can't even begin to get into how deep the editing is on this music app.

ONE HUGE PLUS THAT THIS HAS OVER THE ORIGINAL KORG MS-10 IS THE DS VERSION WILL ALLOW YOU TO SAVE PATCHES!
