Lee, I think you get my point. You HAVE bought your styles. Most EULA's for styles allows you to use them for your own purposes in any way you want.

But I have my doubts that most people getting this software are then promptly going to surf over to Ketron, and purchase a few hundred styles or more...

Up until this point, most Ketron audio styles could only REALLY be played on their own hardware (they didn't translate too well because the best part of the style was the loop), so Ketron was getting a return on their investment in making the styles (styles that good are not cheap - ask Nedim). But take away the need for the hardware, what's Ketron's advantage in making them now?
