Ui24R: BRINGING A MULTITRACK SESSION FROM OUTSIDE TO DO SOUNDCHECK ON THE SOUNDCRAFT MIXER

My friend had the problem that he need to do a soundcheck but the band told him they weren't able to go before the show, he asked me if I had some multitracks with the same instruments in order to at least leave everything and during the performance of the band just fine adjusting, since I did not know if it was possible, I did send the files in waves to him and he could do an excellent work for the band that night.
