Well, I differ in one respect, I use the ketron with a usb midi interface to a Roland keyboard. I have both outputs jacked to the mixer. I then use the thru function to play the sounds in the ketron and can thus use it's soundset and layer it with the sounds from the Roland if I want. The liimitation is fiddling with another sound level, but it sounds great.

I also just use the Ketron and leave the keyboard out if I'm playing a horn.
