Yamaha P-80 Owner's Manual - Page 21

Tuning Tuning makes it possible to adjust the pitch of the P-80 over a 427.0 Hz ... 453.0 Hz (corresponding to the A3 note's Hz) range in approximately 0.2 Hertz intervals. Pitch control is useful for tuning the P-80 to match other instruments or recorded music. Tuning Up ...Z To tune up (raise pitch), hold the A-1 and B-1 keys simulta- neously. X Press any key between C3 and B3. Each time a key in this range is pressed the pitch is increased by approximately 0.2 Hz. The [-/NOM] and [+/YESL] buttons can also be used to tune down or up, respectively, in approximately 1 Hz increments. Press the [-/NOM] and [+/YESL] buttons simultaneously to recall standard tuning (A3 = 440 Hz). C Release the A-1 and B-1 keys. Tuning Down Z To tune down (lower pitch), hold the A-1 and A#-1 keys simultaneously. X Press any key between C3 and B3. Each time a key in this range is pressed the pitch is decreased by approximately 0.2 Hz. The [-/NOM] and [+/YESL] buttons can also be used to tune down or up, respectively, in approximately 1 Hz increments. Press the [-/NOM] and [+/YESL] buttons simultaneously to recall standard tuning (A3 = 440 Hz). C Release the A-1 and A#-1 keys. To Restore Standard Pitch Z To restore the default pitch (A3 = 440 Hz), hold the A-1, A#-1 and B-1 keys simultaneously. X Press any key between C3 and B3. C Release the A-1, A#-1 and B-1 keys. In terms of "Hertz", the overall tuning range is from 427.0 Hz to 453.0 Hz. The current tuning setting is shown on the LED display while the tuning is being adjusted. Tenths of a Hertz are indicated on the LED display by the appearance and position of one or two dots, as in the following example: Display 440 44. 0 440. 440. 44. 0. Value 440.0 440.2 440.4 440.6 440.8 NOTE • An alternative tuning method is available in the Function mode - page 27.
