Hi Ken,
As Stijn mentioned you can raise the volume with the slider, but I find sometimes the volume isn't loud enough at 127, so I have to go in and lower the style and the other voices to match the Multipad, and then raise the main volume level to where I need it. It works ok, but we should be able to edit the Multi Pad like a voice and raise the output even more. I use mine mostly for vocals.
