That's very interesting, nice addition to what I knew so far. And thanks for that every 3 years tip, for I've been seriously toying with getting the current Tyros 5, but now I just might hold that thought a bit longer
I certainly wouldn't want to cause you to miss out on the great sounds that the Tyros 5 is capable of producing if you have the money in your budget to get one. At least I would not want you to base your decision on my speculation on future features or release dates.
I tend to use the profits that I get from my music businesses to buy more music toys and almost purchased the Tyros 5 in the spring of 2014, but took the money that I had set aside for the Tyros and invested in an advanced cataract surgery over and above what Blue Cross would pay for. But surprise, surprise; my wife knew where I pulled the money from and bought a T5 for my birthday this year. I have absolutely loved the sounds that I get out of it. Understand that I love my wife even more.
One thing I'll point out is that getting the Tyros at any point is just the beginning of the investment. If it's going to leave the studio it needs a case which costs another 5 and a half hundred or so. If you want to add samples, premium voices, and styles it requires a flash board ($300.00), and outside of the sales that Yamaha has around the holidays, each of the premium styles cost $160. And the speakers, bench and stand are all separate purchases if you don't already have them like I did.
That said,
Sweetwater has a Tyros 5-76 Demo for sale right now.
