there are some nice Wersi OAS demos on there Abacus. I really like the Wilbraham Classic. I hope you are not offended when i say that i still have not heard from this instrument in terms of sound why any one would pay three times the cost of a normal keyboard for it ?
If you listen to the last demo Richard Postma CD sound samplepack Pop demo 1 it really is quite poor. My brother just heard me play it and asked if it was a cheap midi file. Wersi would do well to just remove that Demo altogther.
Wersi needs to really showoff what the instrument can do and shake off that old image.
