Default Audio Output
Vezér has an output option to Audio Tracks called Project's Default. This output can be set in Vezér's new Audio Preferences, making it possible to easily change the output of all Audio Tracks that using Project's Default as output.
Channel Mapping
This is where Project's Default device's channel mapping can be reconfigured if needed by simply edit the text fields.
By default, the 1st channel of the audio will be assigned to the 1st output of the device, the 2nd to the 2nd, and so on.

Aggregate Audio devices: Vezér's Audio Engine does not yet support Aggregate Audio devices created in macOS's Audio/MIDI Setup, due a known issue with the underlying Apple technology we are using to handle audio.
Pre-Process Audio Filters Option
There is an option in the Audio Preferences to disable pre-processing of Audio Filters when opening an Audio File. This will spare memory and opening of audio files will be happening faster, because filtering results will be processed at the first time you ask for filtered data on an Audio Track.
So we suggest to disable pre-processing if you are using Vezér as an audio player, and don't want to frequently use the audio-to-keyframe feature.
