[78-L] Pitch shifting

[Don Chichester]

The Schulmerich Organ uses a sampling technique.  Each note has a recording of a pipe organ (digitalized) and forms the basis of the organ sound when played through their amplifier and speakers.  Our church had one, and it sounded wonderful.

> > A Synthesizer used to refer to an electronic instrument which could generate an electronic signal with appropriate harmonics to simulate the sound of real acoustic instruments, (like electronic organs and pianos). Now a synthesizer just refers to any instrument which generates electronic musical sounds which usually don't sound like any real musical instrument.
