Getting the Tempo from MIDI Input
You can also have MainStage receive tempo changes from incoming MIDI messages.
When the “Get tempo from MIDI input” checkbox is selected, MainStage listens to incoming
MIDI clock messages for tempo information. If it receives tempo information, the concert
tempo changes to the new tempo value.
To get the tempo from incoming MIDI clock messages
1 In the Concert Inspector, select the “Get tempo from MIDI input” checkbox.
2 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, or tap a new tempo. 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.
Defining the Source for Program Change Messages for a Concert
By default, MainStage receives and responds to program change messages from all
connected MIDI controllers. Some MIDI controllers, however, send program change
messages while performing other operations. You can define the source for program
change messages for a concert, so the concert responds to messages for only one MIDI
device, port, or channel.
To define the source for program change messages
1 In the Attributes tab of the Concert Inspector, choose the device or port from which the
concert will receive program change messages from the Device pop-up menu.
2 If you want to limit messages to a single MIDI channel on the device, choose the MIDI
channel from the Channel pop-up menu.
