Everyone knows my issues with the Audya. But I have said, since the first factory demos I heard, that this arranger breaks new ground in realism and live-ness of sound. However, that realism comes at a price (literally!)
Audio styles really ARE 'real'. You can't GET any more real than that!
The price you pay, though, is that the technology to play them is far greater than what is needed for a MIDI style, they can't be edited in any way (at least the audio parts), and that they are VERY expensive, by comparison to MIDI styles, to produce. Ketron have their loyal fan base, with a strong emphasis on Latin musics, and here you will find the Audya to be head and shoulders above the rest.
But EACH arranger has its' own areas of strength and weakness in the styles made for them. Korg excel at smooth jazz. Yamaha have got guitar driven styles down cold. I like Roland's rock stuff and ballads, Technics had the bigband thing nailed...
And, in all fairness, I think a LOT of each of our personal preferences and choices with our arrangers boils down in a very large part due to this. What kind of music do we like (or need to perform) best? What arranger's ROM styles is the best at that particular music..? I bet 75%+ of us make our purchasing decision with that as the primary reason, even if we don't KNOW that's what's pushing us in that direction...
So.... to compare one arranger to another is kind of futile. Each of them has something that makes them stand out head and shoulders above the rest. And NONE of them have ALL the bases covered.
If I were in Tony's shoes, despite the ups and downs (were there any ups?
) of the last few months, I would still consider myself lucky to have what is pretty unarguably one of the most live sounding, vibrantly styled arrangers available. And I would be VERY hard pressed to make a decision between it and a Korg (those three paltry fills is still a major strike against it, IMO). But it appears you still have BOTH. What is the problem? I would DIE to have both of those in my studio! They are sufficiently different to not be redundant, IMO.
In a world of hunger, some sit at a table groaning with food, and complain that their favorite dish is missing...
