Thanks for the reply guys.I agree with you regarding the gs as opposed to gm2.I was hoping one of the roland modules would suffice.I changed all of my files to gm some time ago.The unit I have is small and only weighs 14 ounces.I am intrigued by the Kurtzweil ME1as I love their piano sounds,but I am not sure if it will play standard midi right out of the box.The size and weight is an issue also as my travel rack is pretty well full.I have A MIDJAY which sounds gtreat but I use it for other applications.Thanks again,Terry
