I have an E4x Turbo (non-ultra). Picked up the Grand Gold Pianos disk from NorthStar Productions. 128mb,96mb, and 32 mb samples. 9ft STeinway, 7'6" & 6' Yamaha.

Four layers of samples that are velocity switched. Pretty well done. I like it quite a bit accept for one thing. The trails on the decays have a lot of quantiztion noise. I don't know if this is a fault of the E4's DACs or the Samples themselves. Maybe a little of both. Although I only hear it playing solo piano in headphones. Put it in any kind of a mix and it's not an issue.

Regards,

Jason
