having both is fine also ...I just don't use the Ts if I have a choice...for me speedy navigation is essential IMO a TS doesn't offer that..but off stage or in studio editing with time it's ok to use for things,...with Tyros previous successes so far and sales a TS isn't gonna limit buyers at all now that a 76 & 61 version is offered.....get ready to see many players jump ship.
