External Clock; Initial Data Send - Yamaha PortaTone PSR-620 Owner's Manual

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 Ac-
companiment, 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.
