No split points
The split point effect is the first factor that easilyidentifies a sample based digital instrument. This flawis strongly criticized by advocates of the pipe organ and results from the limitations in memory that can be economically held within a computer chip. Organ manufacturers are currently forced to use a single sample for multiple keys by spreading it across a region of the keyboard. At the point where a new sample takes over the musician hears a slightly different sound. This makes the end result not totally realistic. Moreover, the ‘scratching’ of the sample makes some notes sound unnatural.Physical modeling on the other hand does not have samples and therefore the split-points do not exist. When the physical model is applied to a stop, there is a natural progression across the whole keyboard just like a fine pipe organ. Another great feature needed for a sound replayer.
