the octave numbered 0 was chosen to correspond to the lowest
audible frequency. Using this system, middle C (about 261.625 Hz)
corresponds to the note @slanted{C} in octave 4 and is denoted
-@slanted{C@sub{4}}. Any frequency can be described by giving a note plus an
+@slanted{C4}. Any frequency can be described by giving a note plus an
offset in cents (where a cent is a ratio of frequencies so that a
semitone consists of 100 cents).
The midi note number system assigns numbers to notes so that
-@slanted{C@sub{-1}} corresponds to the midi note number 0 and
@slanted{G@sub{9}}
+@slanted{C-1} corresponds to the midi note number 0 and @slanted{G9}
corresponds to the midi note number 127. A midi controller can have
up to 128 keys and each midi note number from 0 to 127 corresponds to
a possible key.
