Are you saying that you have a Gem (General Music) keyboard and you can get more than one split point?

I have used the Genesys and only able to get one split point in regular playing mode.

This is one of the most overlooked features in an arranger. You can have 2 sounds in the righthand. So if you need to use a different sound in a split second in the right hand, you can do so with out having to press a button. You can have a melody sound and a brass sound in the right so you play the melody and immediately play the brass line. Also good for call and response. It is even better if you have 76 keys to do so.
