Its much like a Software Motif as most samples come from the Yamaha Motif sampling team..

I have played with it a few hours todat in a friends studio, and it has a much broader engine then Kontakt for example.

If Wersi only could have build this intoo their Engine things would have sounded even better.

I think its a great addon for those that play a Korg or an Audya in combination with VST's and want to have some of that typical Yamaha sounds in their setups. Much cheeper then a Motif rack as this is only €250 and with direct from disk playing in combination with a fast SSD very much usefull for live use.
