We have a gig in Prague next week, and we were going to have to drive 15 hours from Oxford to take the organ because nothing I had tried sounded anything like the Farfisa. Back in the summer I tried the Nord Farfisa sounds, a sample set from the States and several other synths that claimed to be "the authentic sound of the Farfisa" but they all sounded terrible (the samples were good, of course, but there was no useful way to get the authentic vibrato).
I discovered Combo Model F and it saved my life (and saved us having to drive!). I just spent the weekend rehearsing with it, and apart from the occasional stuck key (almost certainly the fault of my keyboard) it worked like a charm and sounded almost identical to the real organ. I set up two instances (one for bass, one for the rest) on separate channels in Mainstage and panned them hard left and right so I could split the laptop output into two mono jacks and plug them into into the bass and guitar amps.
Sorry for the lengthy gushing post, but I'm a happy man.
I just happily donated, and I'll be recommending Model F to anyone who will listen...
