Disklavier

Hallo to everybody,
I'm an happy brand new owner of a C3ProMarkIV, after a long time spent
to decide if and what to buy and more than 6 month waiting for delivery.
I live in Rome, Italy, and I am a retired computer technician
(Windows, Mac, Linux). 

I'm interested in to explore midi editing but I cannot find a
suggested one to work right with XG extra-midi data.
I used lot of professional editors in my life for composing and I'm
not afraid to learn one more editor.

Has anyone found a good product to edit XG? (I've tried for this
answer in the group messages before posting......).

Thanks in advance 

Roberto Fasciani
