Mr. Em...
There aren't any rules here. You'll definitely find some sounds which are "layered" in the traditional fashion which will use up more than one voice. Also stereo samples use up two voices each.
Next Question -
Yes the K2600 IS a virtual analog synth much like the others Nord, Virus and others.
Wilkes-
Sorry but "sampled" waveforms on a keyboard like an XP50 don't quite sound the same as generated waveforms.
