Hi from Bs As Argentina.
Actually I have Sp4-8, before I had Yamaha, so SP4 is some new for me, but the key and touch is really very cool, its like real piano playing. I studing and try to play some kind of clasic music o soem of new age style. So if you have some ideas, so its welcome!
Ahh by the way I'm Russian and living in Argentina for last 15 years
Thanks
