BTW, before anyone 'muscles up' on me, and demands I show them MY guitar emulation in order to be legitimate in my criticism, let me just point out I come from the other end of the spectrum...

I rarely EVER try to do guitar emulation, at least acoustic and nylon, simply because i DO find it next to impossible to stay completely idiomatic and still express what I hear in my head. Real guitarists always achieve this without, so it seems, the slightest effort whatsoever... Hence, I tend to nearly always play with a guitarist!

Leave them to what they do best, and leave myself with what I do best... It seems to work out admirably

But, at least from working with real guitarists (and some quite good ones, too), I feel I've got a pretty good ear for what IS good emulation, and what isn't. Sorry that this is how I feel, but of all the sounds in a keyboard, guitar is the one I generally cringe when I hear someone try to emulate unless they are VERY skilled at it. Of course, in the meanwhile, arrangers are making great strides in achieving believable guitar strumming and picking on the auto side of things, but on the whole, I haven't seen much that can make bad emulation into believable on the 'live' side of things.

Of course, JMO... yada yada yada....
