Tracker Plus - Performance Mode and Recording via USB Audio

Long time Tracker user here and I consider to get the Tracker Plus.

I do a lot of live performances with my Tracker and have a question regarding the way audio over usb works. When one is recording tracks via usb audio while using the “performance mode” how are the effects applied to the audio stream via usb?

Thanks

I’ve only experimented with USB audio but I want to say I saw a stereo track that was just the effects, like a return track. I know CH 1 and 2 are the main output, which confused me at first.

I’m not talking about the delay and reverb effect tracks. As far as I understand the tracker sends all tracks + main + FX-send over USB. However I want to know how things are routed and record when using Performance Mode. I also asked at Polyend tracker Discord server but also no luck. Nobody into recording output?
