Ive had many sleepless nights thinking about whether to buy t2 or 900. Ive realised that i dont need upper 3. I can use one touch settings to set up voices. I mainly layer with strings so its fine. Aftertouch i never used on my T1 so i wont miss that. S.art strings and s.art brass are absent but luckily for me i only use live strings. Brass ..yes i would have loved s.art brass but i can live with it. Other than that i can tell u the 900 is equal to the t2...and i do want to save $1700...and still be able to say i own a keyboard as good as t2.
