I am looking to buy a sound module. I have it narrowed down to 3 choices. The Roland JV1010 and the Korg X5DR or the Korg NX54. I am going to be performing live with a band. I, in particular, would like nice acoustic piano, e-piano, strings, and synth sounds. I need it to be able to do splits and layers and keep them in it's memory even after you turn it off. Being able to record and save performances and play them back live would be nice too. Which do you think is the right module for me.
I would appreciate non-biased answers. Thank you very much.
