Depending on the size of your band, it might make matters worse to try and play in the same sonic space as the other instruments. There’s nothing wrong with doubling leads or at times doubling pads and such, but ultimately you want your band to feel well mixed and blended and part of making that happen is not stepping all over other instruments.
For example, if you have a bass player, DON’T OVERPLAY the left hand! Or if you have a good solid rhythm guitarist who is playing in the low to medium range of their sonic space, then you might be better off laying out or playing higher up the keyboard.
