yahroon Hi, I can't route anything in settings to my Presonus firebox interface. I am using an old MacBook and this interface because it has 6 outputs but I cannot assign them in settings. Is it not supported in StageTraxx?
peter Stage Traxx can only use the standard audio output of macOS as it is a universal iOS/macOS app. So to use your interface you need to set it as the main audio out for macOS in macOS settings.
