Relating to the second part of your question. You can record a style on the keyboard in DIGITAL RECORDING right side of T2. Easy record will record all parts inc Intro's Fills & Endings. You can also add extra tracks if you wish to build up a song. Save on the keyboard (Name?) and it will save as a Midi File which can be loaded into any sequencer.
Although you are not using Cakewalk this sequence can also load a Yamaha.sty (styleFile)
