If you are using more than 1 DAW layer of an SSL console, Logic will by default pick up the system exclusive data sent on the layers that it is not assigned to. This is known to cause MIDI problems, including unwanted recordings of the data and MIDI clock issues.
If you only need 1 DAW layer, use DAW layer 1 for Logic in the SSL console Remote software and either:
Restrict ipMIDI to only 2 ports.
Assign 'none' to unused DAW layers in the Remote software.
If you require more than 1 DAW layer, one of which is assigned to Logic, you can set Logic to only 'listen' to the ipMIDI ports that are relevant in the Environment Window.
In this example, Logic is using DAW layer 3 (ipMIDI ports 5+6):
- Within Logic, navigate to Window>Environment>Click&Ports.
- Select the cable coming out of the 'Sum' output of the MIDI input box, and drag it the left hand side of the box to remove it.
- Drag from Port 5 output to the 'Input Notes' icon (piano keyboard).
- Drag from Port 6 output to the 'Input Notes icon.
- If you use the Caps Lock Keyboard, also drag it's output to 'Input Notes'
- Add any other MIDI devices you wish to use, such as a MIDI keyboard, to the 'Input Notes' icon.
Note: This setting is specific to the Logic song that you have open, so for existing projects it will need to be applied for each one. It is therefore recommended that you apply this change to your default Logic project.
More detailed information about the Logic Environment Window can be found in Logic Pro Help.
This applies to all version of Logic.
