How to remove music from the first audio using the second audio?

Hello, everyone.

There are two audio tracks: the first one contains music, notification sounds, and microphone audio. The second one contains only the same music as the first track.

What needs to be done: remove only the music from the first audio track using the second audio track, while leaving the notification sounds and microphone recording on the first track.
How can this be done in Vegas Pro?
I know about auto-ducking, but that's not quite what I need.

You might be able to separate the audio by STEM separation.

@capslk Don't know how well this will work, but maybe Invert Phase of one of the audio events that has all the sounds. When played back with the other audio event with just the music, it will subtract out the music leaving the other sounds. Of course the events have to be perfectly synced. You may even need to adjust the gain if you hear bleed thru.
