  • Fixes related to the offline-mode.
    The idea is that if you have a main rig where you are connected to, lets say a USB-Interface on a mixer.
    If you open the project on your laptop, without connection to the USB interface, you will enter a “offline-mode” the connections of the USB will be virtual and any changes to the selection of audio device will not be saved. Once you connect to the right audio device the project will be online and your patch will remain intact.
