If you like its tonal character you will never want to give up posession of it. Everything is arranged logically and can be accessed quite quickly. It has a quirk that on entering the multi-timbral 'system' screen the current patch defaults back to 1, which is annoying if you wanted to continue tweaking your other patch assignment. One thing I really dislike is the fact that it has only one multitimbral set-up. I have to constanly save the 'panel settings' to disk and load a new set-up when I want to refer to another song.
Effects are good, although the delay times on the delay effects are a bit limited.
Talking of outs, I quite like that it has an extra sub out, to which any sound can be routed to. Pretty extensive on features. There's a finesse about the whole shebang that quite escapes description. The sonic power is quite awesome - despite some of the modelling parameters sounding a bit nasal and honky some of the simulations are very good. I am constantly asked if that's a real guitar or drum drums and I have to shock them by saying it was a synth.
