Hi Giovanni
I am afraid that sound samples of the Blackpool Wurlitzer are copyrighted and only 1 manufacture has the rights to them. The previous Blackpool Wurlitzer samples provided by Total Transformation Technology have pretty much vanished, as they do not have the rights to them. (According to reports? the Tower Team discarded the samples as not being of good enough quality, and they were later picked up by TTT)
Other Wurlitzer’s can be sampled without problems. (Providing you get the owners permission)
