How do I configure Logic for use with Matrix?
Logic will automatically scan for control surfaces when booted. Depending on the Logic version number, it should show 1 Mackie Control and 1 Mackie Control extender when it finds Matrix. These two objects are sufficient to have full communication between Logic and Matrix using the MCU protocol . In some circustances Logic will find more objects than these. In this case please delete the unnecessary Mackie Controls and Mackie Control extenders.
You should also ensure that the Mackie Controls are configured to use the correct ipmidi ports. If Logic is on DAW layer 1, the Mackie Control object should be set to use Port 1 in and Port 1 out. The Mackie Control Extender should be set to use Port 2 in and Port 2 out. For subsequent DAW layers please refer to the Matix manual.
