maybe I didn't explain myself well, my goal is to create a customized usertrack for example of one minute with an audio file that is stereo, once loaded in band in a box it plays in mono my format used and exported with Cubase is .wav 44100 16bit and I also tried with 24bit why does this happen? I understood the creation procedure very well I put inside the folder D:\bb\RealTracks\UserTracks with the .sgu file with the same names and it is recognized by bb
