Chas exactly just look around that is why backing tracks are taking over and in that regard lets the musician just concentrate on just playing his instrument instead of worrying about all the features of an arranger kb, parts, styles, volume,settings,registrations, transpose, playlists, knobs,.....instead just push a play button on a device and you can enjoy using one instrument with two hands as if you were in a band which is the backing track, mp3, smf, good points Chas...it's too late for the target market it has been set the line is drawn and until the previous home organ generation is gone it will remain like this......and the manufacturers know this.
More choices = more $$$$ to be made,....
