Unfortunatelly things are going the other way that discussed here. Our last TOTL arranger even came out without a sound editor. And it took over a year just to get some kind of sound editor which is not even close to lets say Motif sound editor. And most of the people even said hallelujah. Let's face it, majority of arranger players are home amateurs, and they'd rather let instrument play by it self then actually learning to play an instrument. For some reason it's easier to learn all of the combinations for two finger chords than taking the same time and learning actual chords. And "transpose" button came out of heaven .
Unfortunately I don't think it will get better, I think it will get worse. We will loose even more features. They will dumb us down even more and we will still like them and we will still buy new keyboards thinking this one will make us a better player.
There is no reason to blame these companies, it's all our fault. Just like with everything else in life.
