I’m new to Stagetrax so I’m sure I’m missing something. I’ll make my Trax, put them in a folder. Then load them into Stagetrax. What’s happening is when I go to play the whole track back, it will have a drum track from another song. Weird right? Any ideas

This is a problem with your filenames. All multitrack files are put into the same folder. So make sure filenames are unique. Instead of using for example "bass.wav", use "songname - bass.wav".
