The sounds within the MIX vs solo is whats important to me when I perform and yes they are fantastic...If they never change the sounds or styles again on today's TOTL/MOTL I would be very happy at what we have in the way of styles & sounds not to mention besides all that you could also edit, tweak and create your own too, no matter what you do it will always still be an arranger, if you used arrangers since the beginning like myself you know how far they have progressed,.....Big Changes in features, technology, navigation, weight, design, it's where their efforts need to be addressed IMO.
