I've got a 15 year old Alesis drum machine that completely blows away the S910 for punch and impact, live. The trouble is, most of these arrangers are designed for hobbyists, sitting at home in their living room, noodling away with next to no skill or experience (sorry, all of you that DON'T fit that, but it's true, IMO), and most of them don't have a CLUE what is needed to impress a pro.

Pro's come from LIVE MUSIC backgrounds, and want something that approximates that experience for them and their audiences. Although today's MOTL and BOTL arrangers, especially the market leaders, are marvels of integration, most of them have a LONG way to go before they even sound as good as stuff from the eighties and nineties that was DESIGNED for pros... not hobbyists.

BTW, I remember from my home organ sales days, those things were bought and held on to for a VERY long time. Nobody that just took playing the organ as a hobby traded around every couple of years or so. They bought them like they bought pianos. A once in a lifetime purchase. I have a suspicion that many of today's hobbyists that bang down $3500-4500 for a TOTL arranger aren't looking to replace it in a couple of years... especially as how little gets added to it in that period.
