I'm sorry, but if you can't hear how much better the drums and guitars are than MIDI arrangers, you are likely to think that there really isn't that much in it.
For many people playing live, having the rhythm section have same impact as real drums is the ultimate goal. Ketron's live loop drums can't GET any 'real-er'
At home, or in a low level background situation, this might not be what you are looking for. But want to make an impact, AFAIK, there's nothing that comes even close, all around.
Not that this ALONE is enough to make it the 'best' at everything, but if a great 'live' sound is what you are after, there isn't much competition. If this were priced $1500 lower, I think the vast majority of arranger players would be buying one. Sadly, it's out of reach to most. But I'd buy one in a flash if it were down close to the price point (new) of my G70...
There's a LOT of stuff in the Audya that hasn't yet got much of a demo workout. REAL arpeggiators, for the techno crowd. Key-triggered loops for the hiphop and rap crowds. Looks like Ketron are at least CONSIDERING some kind of 'Chord Sequencer' for the two handed amongst us
When the software to incorporate your own audio loops gets added, the possibilities multiply radically.
You want the 'same old, same old', best to stick to the 'same old, same old'. Ketron have added several VERY musical functions not seen on a hardware arranger yet, and beefed up some of the things that others only have a LITTLE (four break/fills, for instance, instead of the paltry one), and many of its' best features lie hidden in the fine print of the specs.
But that 'live' sound ought to be hitting you between the eyes. If you can't hear THAT, it's no wonder it fails to impress...
