I just upgrade the X3 with a Mac (Leopard), no problem.
there really is something to find his way among all the effects available
I particularly like the XLR mic input since my application is a bit special:
back the sound of a piano (acoustic) via an SM57.

UTILIZATION

Editing is OK, it takes time ..... as with any
The configuration is the X3 is very convenient for live.
manual ok

SOUND QUALITY

The effects are effective! yes it is on.
I use a Yamaha U1 upright piano or 1 / 2 tail Kaway or Steinway.
I use a lot of filters, delay, and finally distos .... just about everything.

OVERALL OPINION

Bought on sale, the price is right.
Yes the same choice!
