What are some good sounds that you use U13???
The only sounds I use are the Dark piano, piano and strings, RnB soft (rhodes patch) and the organ sounds.
You just gotta experiment. If you are ever a back up keyboard player dont limit yourself to string and horn sounds, try some out of the box sounds.
There are a lot of sounds hat were on the motif that they left out

like the minisub bass patch) That was the only smooth bass patch they had, so i dont know why they excluded it.
