Yes I agree. I'd check Yamaha's new FSR-1 module which is formant shaping & FM (DX7 patch compatible) Does FM plus vocal emulations and a lot more. I haven't heard this myself yet, but it looks very interesting. But I must admit I still won't get rid of my SY77 which I am very fond of for it's AFM voicings. And they improved the factory set by the time they released the TG77 so it's actually better straight out of the box.
