I've been to the tyros official presentation. There are only 10 mega voices as stated. The mega voices are multisamples in velocity terms having open and mute string sound with pick noises and slide effects etc for the guitars. It is most effective in the programmed backings, it is not clear if exactly the same sound can be produced by live playing, but the sound is undoubtedly very good.

The main difference to 9000 and pro are the styles which are very much superior and much closer to the competition now in range and realism.

It only weighs 12.5 kg so will be popular with giggers. In the UK the price is £2,400 without speakers, £2,600 with speakers
