lukitoh,
Glad to meet you as well. I play sk880ps keyboard. It is identical to WK8 with the exception that it has 88-weighted hammer action keys plus no speakers. It has a harddrive, and I added 8 megs of battery backed memory and vocal harmonizer.
When playing the Solo piano, my left hand does usually play the bass. I usually play appregos. Therefore, when I play with an arranger, I use full backing styles with multi-fingered mode since I use 4 fingers for the chord.
