Hi. If you have connected the MX200 to audio inputs and outputs on your MOTU interface, then the simplest way to use it in Podium is to use the “Import Hardware Definition” command from the “Device” menu on the project page. Select the “Generic Effect Device” from the file list. This will open a dialog where you can select which audio inputs/outputs that you have connected the MX200 to. After you press OK a “Generic Effect Device” mapping will be added to your device list. You can customize this mapping afterwards, like giving it the name “Lexicon MX200” and change if you are connecting with mono input instead, etc.
You will then have this mapping available to be assigned to an audio track, similar to how you would assign a plugin effect.
