Footnote -
You're not actually controlling the laptop at all. The sound source is the Korg.
I find the dual seq so efficient..I think the laptop may just be put into reserve status very soon. Except for weddings or high energy DJ stuff, the on board seq is great.
In a bigger dance setting with lots of confusion and requests...I need the laptop because it shows me more than 100 song titles at once ( in many different genre folders) ....like a jump start for my brain in case of distraction.
