Picked up a Tyros 4 yesterday and I'm having lots of fun with it.
Getting used to the blue leds now.

Some great new styles and voices on this machine.

Vocals predominate the additions from the Tyros 3 and although a few are a bit gimmicky, they’re also a bit of fun.

There are some other really great vocals on this machine however especially as they are also incorporated into the styles; for example ‘Surf Rock’ intro 2 in a minor key, just calls out for The Mamas & the Papas' 'California Dreaming' with the great backing vocals. Intro 3 inspires a round of Beach Boys stuff.
All good.

It has a beautiful new Vibraphone for your jazz stuff along with the new snazzy Jazz violin.

Big male choirs with a huge symphonic sound come alive with the ‘Ethereal Voices’ style, speaking of which the new 'Symphony Horns' are really incredible, such a big, BIG sound, much bigger than on the Tyros 3, great for the Imperial March from star wars.
There's really plenty of good stuff on this machine and I’m having a lot of fun exploring with it.

However there is some not so good stuff in that the so-called new pianos appear to be exactly the same as were on the Tyros 3 and thus, as in the Tyros 3 remain second rate, to my ears at least.
(I’m disappointed with this).

The VH2 (Vocal Harmony unit) is quite different from the VH unit on the Tyros 3 with less propensity to distort and it also sounds clearer than on the previous models, however if you have a deep voice, as I do, it's going to need a fair bit of editing to get a good sound (I haven't got there yet), It's also missing 2 of the VH-types/presets that I used all the time with the Tyros 3. The T4 VH unit seems setup for females or guys with higher voices as is out of the box. I'm still working on the VH but it's early days.

Over all, a great machine sans the pianos.
I'm going to be busy and now's my chance to clean up all my folders (again) as I load up the new machine.

Question:
Does anybody remember how to check remaining capacity on the USER Drive memory of the Tyros?
