- The limit on the number of pitches is related to the duration
- of the CD's long list of samples... it is NOT a limit that need concern
- any musician, just a figment of using a finite number of samples
- (not finite SAMPLING RATE, finite NUMBER OF SAMPLES) to represent
- the sound. For a one-hour CD, the frequency granularity is
- in the few-microHertz range.
-
- That's approximately 0 semitones, in musical jargon...
