Hi, my main instrument is Hammond organ, and I use a Kurzweil SP4-7 on which I split the keyboard to play bass in the left hand and other sounds in the right hand. I play in a blues band, where I use the SP4 for acoustic piano, and in a soul/jazz/lounge band where I use the SP4 for accompaniments using electric piano, strings, pads, etc., and for solos using sax, trumpet, flute, etc.
