Yamaha S90XS Features Not Found in User's Manual

The purpose of this blog is to share any cool things that you can do with S90XS. This is also an opportunity to ask questions and I will shoot the first question. How do you delete a track from the internal memory. I have not been able to find this in user's manual.

Nocturne N100 Built in Metronome?

Does anyone know if N100 has a built-in metronome? User's manual does not mention anything about metronome, but I have heard that it has built-in metronome. If does, please let me know how to use it.
