jwyvern,
Thanks for that John.
The T1/T2 Live Grand which luckily Yamaha have kept on the T3, is without doubt a cleaner more even sound, although IMO still a little thin but much more usable than that Concert Grand thing on the T3 and as you say the Live Grand sounds more “live” on the T3.
As far as standing out in the mix the Live Grand sparkles, whereas the Concert Grand although it does cut through, doesn’t quite have the same presence.

It's such a shame because the new T3 Concert Grand piano could have been SO much better, after all the last octave C5 up is really very nice as is the lower register (very rich), it’s just such a shame about the rest of it.
I’ll also use it on occasions, but I find playing an octave higher where possible helps avoid that horrible mid range “Toy Piano” sound that I find so irksome.

Chris.
