The SA-47 mini keyboard comes with a new sound generator and an 8-voice polyphony. More than just a toy-extremely small children will have lots of fun playing the 32 keys right from the start. The SA-46 and SA-47 mini keyboards come with a new sound source and 8-note polyphony. It includes 100 tones and 50 rhythms. This is also disclosed by the LC display: the SA-46 and SA-47 are serious playmates! Another highlight is the simple change-over switch: on the SA-46 for switching between the piano and organ sound, and on the SA-47 for switching between the piano and reed organ / organ sound. Both instruments have a cool retro design-on the SA-46 the design combines with a bright green yellow and on the SA-47 with a slick gray.
