Don, all of the suggestions are coming from folks that were not in the room you played..

They are listening to PC speakers or headphones..

On top of that several are use to the Yamaha sound ( not live sound as the Ketron)...and they (DNJ and others) are use to cutting bass and pumping up the highs..(They have nursing home ears)

You are playing a room, and want to sound like a real band...the Ketron has great bass and drums, that sound live..When did you ever struggle to hear the bass of a live band...presence is there, and you feel bass..The drummer is also out front..dynamics...

Don't judge your performance of a live room based on a recording being heard on a pc..
We don't want to program and perform our sound to be live, and critic it to sound like a radio
