Worse than 2, when I went through the cherry audio GX80, which is a faithful recreation of the CS80 with some GX1 presets too, playing a chord with every single of of the original presets was a song I knew (and in the presets is the whole of blade runner too).
Presets are handy to give you an insight into what you can do with a thing, but shouldn't really be relied on as the only thing, unless thats what you want, in which case you would probably be better with a rom based thing - I have a DS61 and its beauty is that if you want a sound, you select a type (piano / organ / strings / wind / voice etc) and then select one of the presets - its not a synth and doesn't try to be, its for making known sounds. The argon isn't that, although when I want to synth anything, I always end up with the Waldorf Blofeld for hardware (or equator 2 on the mac).
