I'm going to play in a band. I will use the Roland VA76 like an arranger and the casio wk3500 - for completing the VA76 - those two are on a double stander. And on the other side, a friend is going to do stuff with the Motif. Do you guys think that will work out? I'm using the casio because it has cool sounds, and i'll play with the left hand on it and on the va76. The motif is for the other guy. Do you think that the Motif is necessary ? or i should play on the va76 and him on the casio...? Please, advices... Thank you very much for your answers.
