I bougth a new SP4-8 about 5 mounth ago. I play in a funky band. I'm searching the real sound since years. I had korg or roland workstations, but I tired these sounds some mounth. This is the first Kurzweil product's and I'm very happy. I love the kurzweil sound day to day. The piano, epiano, organ, string programs is very realistic. And I like this keyboard the drawbars. I can use my tablet/phone with OTG USB and I can change the parameters in real-time. I bought to the soundtower editor software, so I can edit programs and setups fast and easy.

Where poeple listen, they just praise.

I'm satisfied, this purchase was the best dicision(price/quality).
