Clock selection
Manufacturer documentedGLOBAL MIDI Clock offers Off, Internal, External and Auto. Off disables MIDI clock reception/transmission; Internal supplies the synth's own timing.
External follows incoming clock from MIDI or USB and requires that clock for tempo-related functions. Auto falls back to internal tempo when incoming clock has stopped for more than 500 ms.
Keyboard and transport
Manufacturer documentedLocal Control off disconnects the keys from the internal engine to avoid duplicate playing through an external sequencer. Leave it on for direct playing without MIDI return.
Rx Transport is a separate receive setting. Receiving clock does not by itself establish that start/stop messages are enabled.
