The new MO series sound very good indeed. The MO series.., just as any arranger is IMO just as capable of doing the (one man show).

It falls down to the person behind the keys with the skill capable of utilizing the workstation, and making it work for the crowd. I've seen one man shows many times where a workstation is being used for playing many style of music from traditional to modern. Again.., the determined workstation player will make it work. Arrangers and workstations are both amazing keyboards.., and each require a slightly different set of skill to use for one man band performances.., but the same outcome is possible on both.
