Hi BEBOP!
I use XG works quite a lot, as I build many midifiles from the Tyros. All the Yammy styles can be used in XG works, I write text and chords for the lyric display etc. For me, it's my most used sequencer progam as it is tailored for Yamaha, and it is really user friendly as well. I can highly recommend it as it is well suited for all your 9000 styles.
