Well, at least the boards are still pretty different, in their sound sets and their ergonomics/interfaces. But if it was mostly the "reasonably priced, lightweight board with 76 decent feeling keys" that pushed you to that purchase and you just wished there had been a 76-key FA instead... yup. If indeed this has a different action from the 06, which is still a bit ambiguous.
I bought the JP-50 as a controller/audio interface for my laptop rig. If the FA-07 has the same action, the lower weight and better DAW integration would make it a more suitable solution for me.
But I'm not that mad, as I got my barely used JP-50 (with flight case) for $1000, which is a good price.
Still, the traditional 16-part workstation layout and more powerful MFX make this a far more comprehensive package than the JP-50 is. With aftertouch and a built-in PSU it would have been a perfect replacement for my Fantom X7.
I think an FA-07 on top with a Yamaha MX-88 on the bottom makes for an incredibly versatile and lightweight combination at just $2500. Amazing.
