Well, I got some of the video processed. For those interested here is the link.
https://youtu.be/QKfQznJyGwMDonny, in my opinion, the PA4X does not come close to competing with the Ketron SD7.
Sorry if that offends anyone here but that is how I see, hear, it. Keep in mind I don't care about all the fancy features - I am an arranger player - not a composer - I don't use samples, I never use midi files, and the only time I DJ is if my setup fails to work at the gig. I much prefer the rhythm sections of the SD7 styles to the PA4X - seem much more real to me. Anyway, that is just my opinion.
