CS I have no need for , I never used it on my G1000 also....I rather play thru ...Yamaha better step it up FEATURE WISE on their next TOTL arrangers, players need more then just great sound. I hope we see some Tyros feature improvements soon....Ketron has kool features that use to love, Drum lock, bass lock, simultaneous mode play etc.....Roland has best D beam, sequencer & makeup tools, in the business...I'm hovering but my helicopter is slowly running out of gas!
