I used to have one, but I traded it in and forgot the names of the patches... But anyways... Try layering an Acoustic Piano with an EP and strings... Or for a more dramatic sound try layering bells... In my opinion, the Triton Le Piano is too weak and too lame to be played alone...
Besides, it's 2009... be creative!!! You might wanna try just strings for the intro to the song, then switch it up to a piano/strings hybrid... or try a strings/bells hybrid, or maybe even pads... you never know... Try to develop a sound of your own!
