Yamaha PSR-520 Owner's Manual - Page 75

Overall Functions s Local Control ..."Local Control" refers to the fact that, normally, the PSR-520 keyboard controls the internal tone generator, allowing the internal voices to be played directly from the keyboard. This situation is "Local Control ON" since the internal tone generator is controlled locally by its own keyboard. Local control can be turned OFF, however, so that the keyboard does not play the internal voices, but the appropriate MIDI information is still transmitted via the MIDI OUT connector when notes are played on the keyboard. At the same time, the internal tone generator can respond to MIDI information received via the MIDI IN connector. This means that while an external MIDI sequencer, for example, plays the PSR-520 internal voices, an external tone generator can be played from the PSR-520 keyboard. The default Local Control setting is ON. oon Local s External Clock ...Reception of an external MIDI clock signal can be enabled or disabled as required. When disabled (OFF), all of the time-based functions (Auto Accompaniment, SONG recording and playback, etc.) are controlled by its own internal clock. When MIDI clock reception is enabled (ON), however, all timing is controlled by an external MIDI clock signal received via the MIDI IN terminal. The default setting is OFF. oFF ExtClock • If the External Clock function is turned ON but the external clock signal is interrupted for more than 400 milliseconds, the internal clock is re-selected automatically. • External Clock setting is retained in memory even when the power switch is turned OFF, as long as batteries are installed or an AC adaptor is connected. • When the External Clock is turned ON, the song recording/ playback will be controlled by the external device. s Initial Data Send ...Transmits all current panel settings to a MIDI data storage device before actually recording your performance. With the "InitSnd?" function selected, press the [+/YES] button to start transmission. When the data has been transmitted, "End" will appear momentarily on the display and return to the "InitSnd?". YES InitSnd? • The song data will not be played back correctly, if the panel settings for the song has not been recorded in advance. To record the panel settings to an external device, engage the external device in the record mode and execute the Initial Data Send operation. • The "InitSnd?" function can be quickly selected by pressing and holding the [SYNC-START/ STOP] button. 74
