I have had good experience with Ketron, starting with Audya, then SD2, SD4, and the now the SD40. I am fully aware of the problems others have faced in the past, but I have found my products solid as a rock. The Audya,IMO, has the best live sound in styles, and about on par with my PA4x in lead sounds. The Pa4X is second in styles only because of personal taste, I suppose. However, we are only talking about the sound. When you add in features, navigation, workflow, etc., it is too subjective to discuss. I use the Audya more for my band and when I don't need the added features of the Korg.

As to why I don't use the SD40 as my main AX, I don't have one, but it is used as much as the others, depending on the type of gig. I could very easily use the SD40 and SK1(or any controller) for any and all of my jobs, but I want to keep fresh for repeat audiences, and we all know that songs can employ many different styles. Well, as well as different songs, I have my core of two hundred songs in each.

In reference to Gary's observation, I may have agreed with him until the SD40. The only possible drawback is that a module does not have all of the live buttons the SD7 has, but I have made registrations that have done away with the need for lightning fast changes. For all intents and purposes, I have a rock solid SD7 and Hammond B3 at my fingertips, and I am delighted at the results.

Thanks for asking. Donny.
