I have tried unsuccessfully to replace My KETRON keyboards with Tyros 1 and 3, Korg PA1x, 2x for the past 10 years or so, I have Audya5 for several years now, frustration with lack of styles , but found myself keep coming back to KETRON sines ms50' ms100, X1, sd1pro, now audya5 because of the real live band sound. Another thing is that I play with a guitarist, and only KETRON that I'd find cut thru and remain presence in my band outing with guitarist. Love Tyros 3 sounds awesome by itself, but almost lost with the guitarist playing. I have also Korg pa900, but for styles sound, it's Audra.
