A great resource for new and seasoned S‑50 / S‑550 / S‑330 / W‑30 sampler owners. A lot of interesting information is here along with DIY's, Start-Up Disks and Free Sample Disks. In the late 1980's, the S‑50 and S‑550 were two of the hottest samplers on the market because of great sounds, free sample libraries and the ability to connect a color monitor and a mouse for easy menu navigation. These samplers can be found for incredibly low prices on eBay and elsewhere. I purchased a near mint W‑30 for only $35. It's now an indispensable keyboard in my studio and a real workhorse. Granted... this is old technology by today's standards, but still... great sounding instruments!
