MO (pronounced 'mo') is an entry level music workstation by Yamaha. It is essentially a Motif ES without sampling capability, expansion slots, ribbon controller or keyboard aftertouch. It also has half the polyphony and less advanced connections. There are two versions of the MO, the MO6 and MO8. The only differences between the two are the bigger size of the MO8 and its full-size 88-key hammer action keyboard compared to the regular 61-key keyboard of the MO6.
