I quit using the Yamaha and mainly use the micro arranger because it sounds more like a live band on stage. I had this issue before and I know it has been discussed here and it's a matter of personal taste. I might move into a pa 600 later. But for now the micro is all I really need. It's a fun little machine. I've arranged my performances around a MP3 player or laptop playing my backing tracks along with my micro arranger and this setup works great for me.
