Get the tempo from MIDI input in MainStage
MainStage can receive tempo changes from incoming MIDI messages. If you select the “Get tempo from MIDI input” checkbox, MainStage listens to incoming MIDI clock messages for tempo information. If it receives tempo information, the concert tempo changes to the new tempo value.
Get the tempo from incoming MIDI clock messages
In the Timing tab of the Concert settings Inspector, select the Get tempo from MIDI input checkbox.
Choose the MIDI clock source from the Device pop-up menu.
When the “Get tempo from MIDI input” checkbox is selected, the Tempo slider is dimmed and cannot be edited. If MIDI messages MainStage receives do not include MIDI clock information, MainStage uses the concert tempo setting and changes the tempo when you select a patch or a set with its own tempo setting. If MainStage stops receiving MIDI clock messages, it continues to use the last received value for the tempo until you select a patch or set with its own tempo setting or tap a new tempo.
