Strange things happen after import. Track 1 and 2 are not played back. As the video shows, when the mixer is called up, the logic of the M/S circuit is incorrect. Un-soloing the second time does not un-mute the remaining tracks. All tracks are muted.
If you return to the track display, the two events in track 1 and 2 have disappeared. The error can be reproduced.
Menu items “Close” and “Exit” have the same function and end the program.
