I think Nigel may want to do something about this thread. Here is it you have persons accusing a representative of a company of not answering a question an implying that that representative is lying when in fact the representative did answer the question but stated he could not reveal every detail.
If I were Ketron I would not put up the demos just because persons on this forum (who appear not to want to purchase but to cause confusion and no matter would keep doubting the capabilities of the Audya) say so. I would put up the demo as the marketing plan dictates.
When Yamaha or Roland came out with a new arranger, I did not hear any one saying can that new arranger play a C 6 + 9 chord? Look, if Ketron manages to get the Audya to sound good, what does it matter how they do it or what actually happens with the audio track.
I am sure Ketron has a marketing and production plan and it is probably not based on the closed arranger plan that we are accustom to. It appears that Ketron is moving to a open source production plan so on like the T3, the release of the Audya is not the beginning and the end of that keyboard.
