Apple MainStage 2 - Manual (Page 141)

After the Performance
Before closing your concert after your performance, remember that, for any screen controls
for which the On Patch Change parameter is set to “Reset to saved value,” any changes
to channel strip parameters or plug-in parameters you made while performing revert to
their previously saved state if you close the concert without saving. If you save the concert
before closing, the new values are saved in the concert.
Tips for Complex Hardware Setups
It is highly recommended that you test your concert thoroughly using the same setup
you plan to use in live performance prior to performing, at the performance location or
venue if possible. This is especially important for more complex hardware setups.
Using Multiple Keyboard Controllers in Performance
If you plan to use multiple keyboard controllers when you perform, you can choose
whether screen controls respond to MIDI messages from all controllers or only a specific
controller and whether channel strips receive input from all controllers or only a single
controller.
In Layout mode, screen controls can be set to respond to MIDI input on all MIDI ports
and channels or to only a specific device or channel. To have a screen control respond
to MIDI input from all controllers, choose All from both the Device and Channel pop-up
menus in the Layout Inspector. To have a screen control respond to a specific controller
or to the same channel as the keyboard screen control, choose that controller from the
Device pop-up menu.
In Edit mode, you set the device from which a channel strip receives MIDI input in the
Key Range section of the Channel Strip Inspector. By default, channel strips receive input
from the first controller in the layout. You can set a channel strip to receive input from
another device in the Input pop-up menu.
Using a Different Hardware Setup in Performance
If you use MainStage with a complex hardware setup, for example, with multiple MIDI
controllers or MIDI interfaces or with multiple audio inputs, you will achieve the best
results when you use exactly the same hardware setup you used when you created your
concert.
If you plan to use MainStage with different controllers, interfaces, or other devices than
the ones you used to create your concert, you need to relearn your hardware assignments
using your performance hardware setup. To facilitate working in this situation, you can
create two separate layouts, one for your studio setup and another for your performance
setup, with corresponding screen controls in each layout. Before you perform, import the
performance layout into your concert. The hardware assignments for your performance
setup are imported with the layout, and your mappings are maintained.
