I always thought it would be a great idea to be able to press the Voice buttons and have your favorite preselected piano, trumpet, sax, whatever come on at the touch of the button. So if the most used guitar voice is Jazz Guitar then when you press the Guitar Voice button up comes that voice already engaged. Or if Sweet Trumpet is your most used trumpet voice, just press Trumpet and the Sweet Trumpet is engaged, etc. And also be able to group your favorite voices for each voice catagory in order of use for quick access.

I also would like the original system of accessing user voices to return to what it had been on my T1 and T2, and I see is used on the S910. And that is, the way I would use this feature for quick sound changes is I'd set up the first user voice I was going to use later in the song first, then I'd either use ots or reg mem. Then to quickly go to my preselected user voice later in the song I'd press reg mem 1 which was set to piano in R1, then go directly to my preselected user voice. This allows you to go from a two or three layered ots or registration in a zip. As it is now, if I press preset 1 which is still piano R1, regardless of what user voice I had set up, it will go to the piano voice in the user section. Whatever is set up in the reg mem buttons now, whatever the last button is pressed it brings up one of those voices in the user section.

As it is now, the only way you can preselect a user voice to be used later is to go from ots to user, but if it's a layered voice and if it has harmony on, you have to hit several buttons to pull this off.

So, between reg mem buttons not being in the center, to not being able to access my user voices as I always has, the T4's way of doing this has been a major letdown for me in this respect. If it wasn't for the great sounds, styles and voices, I would have stuck with my T2. I don't know when the switch took place, whether it was the T3 which I never tried or the T4, this is a problem area. Like I said it still words the old way on the S910 and I'm thinking it may be an oversight by Yamaha.

I actually hope that an OS update will fix this for the T4.
