It's amazing how the bashing continues. Yamaha is listening and incorporated a few major things:

1. vocal harmonizer
2. scat / human voices
3. tuned drums option
4. more styles - more articulation

At the very least it is one company that moves forward, very quickly. Lord only knows what the unveil next and it may be too late for the competition to catch up.

As for pricing - do you expect a company to digress in MAP?

I haven't owned Y since the 910 days, but the major things missing for me (for live play) have been addressed ONLY in the T4.
