play midi file Mainstage

Hi

This info is in the MainStage 2.2 manual, which seems to have disappeared from the Apple Manual site (!?)

You can also send MIDI messages, including SysEx and continuous control messages, to your connected MIDI hardware devices using an external instrument channel strip. The Channel Strip inspector includes a Send MIDI File control where you can select a standard MIDI file with the information you want to send.

To send a MIDI file using an external instrument

In the External Instrument Channel Strip inspector, click the MIDI Output tab.
Select the Send MIDI File checkbox, then click the Select button.
Browse to the location of the MIDI file you want to add, select the file, then click Send.

The MIDI file is sent immediately to the port selected on the external instrument channel strip. The MIDI file is re-sent on patch change just like the other options in the Channel Strip inspector (such as Program Change or MIDI Clock messages).

Only SMF (standard MIDI file) types 0 and 1 are supported. MIDI files are sent sequentially, one at at time, per concert. If you switch rapidly through several patches that send long MIDI files, the MIDI files are queued and sent in succession. MIDI messages are sent at the tempo stored in the MIDI file.
