That is what I am saying..I have T4 too.I will sell it because I think it is not made for professional.Sure you can use it as I have used it for live.
But for a professional instrument that cost an arm and a leg not to have simple stuff that I already said above is inexcusable.YAMAHA is dumbing us down by saying we don't need those things and guess what,we are helping them .In 4k and more instrument we should have those things without any exceptions.I am not comparing bk5 to T4.I am just saying it gives you much more for the money.
