> There is absolutely no comparison: not a percussive piano banging on metal strings, not a plectrum on a lute such as guitar, no synthesizer can come anywhere close. Electronic organs can approximate the sound, but not the feel, grandeur, and mighty power of a full-throated organ.

The whole point of TFA, as well as the software it is really about, along with other excellent attempts to physically model pipe organs (e.g. Aeolus) is that actually a synthesizer can come very close indeed.
