Topic: MIDI input control for Mac Logic X (MIDI remote, ARC USB etc)
The problem: Logic automatically reads data from all MIDI input ports, and also reacts on that data. Naturally this can cause unwanted behavior if remote controls and other stuff, not intended for Logic, are used with the computer Logic is running on. This might be TotalMix FX as well as the ARC USB or any other MIDI sending device.
For whatever reason Logic does not include a simple selection dialog, which of the system's MIDI inputs should be active for Logic. Instead ports have to be manually 'excluded' from Logic, which is anything but a simple procedure. There exist several discussions in the web, here is one that we found useful:
We followed the steps described like this:
- In the Preferences of Logic X under Advanced Tools set the checkmark for MIDI
- Thereafter one can choose 'Click & Ports' from 'Window, Open MIDI Environment'
- Under 'New' create a 'Monitor'
- Drag that one down and connect it with the port that should be excluded for Logic (the port where remote info etc is coming in). See screenshot (magnifier/glasses needed to perform the connection).
Update: there is a new firmware for the ARC USB available that changes the ARC USB Midi communication to SysEx. That solves the Logic problem. See here:
