Hi Lee,

Actually got the T4 right after the A4. Is was planned that way. I wanted to do my own comparison side-by-side! But I also knew I would sell one or the other.

Bottom line, simplicity! or, ease of use. The T4 is just much easier to use, it interfaces very well with my Roland V accordion. It has IMO very good sounds, especially the ones I use, trumpet, clarinet, sax, guitars vibes.

If the Audya had all the OTS set up, it may be a different story, cause I love all the Ketron sounds as well. But I'm just to old to try and add all that. I know AJ is supposed to be working on software upgrade, but when? And how much?
I also never got my accordion to work properly with the Audya. Probably operator error!

Basically, arrangers and accordions are my hobby, however, I do play out sometimes; not nearly as much as I used to. It was strictly on the weekends, I never quit my day job.

I play country, old standards, polkas (when I have to). I actually worked a job last weekend playing accoustic accordion. For a fellow's 80th birthday. There were about 75 people from time to time. I played lots of Italian, and French, old pop, and movie tunes. About two hours worth. Can't say I strolled, at my age its more of a slow shuffle! But, I did mingle!
