These changes bring up an interesting point to be made..

The EA-7 lacks a 16 track sequencer, so you can not capture any performance to midi. You are not able to add any new midi tracks to your project.

So you need to use a prepared midi sequence from other sources.
My case, I have the G70.

The BK9 is a better choice over the EA7, if you need and use this feature.. Both , the EA7 and BK9 record wave.

Just making aware a difference in these two keyboards, and a situation where it comes into play.
