Playback isn't working for a four-voice texture

UPDATE. I’ve managed to fix the issue by reimporting the MIDI file using “Ignore the original tempo markings” button. No need to investigate. If I had to guess, I’d blame the “Meter: 1” anacrusis from the import

Hi, I’ve tried to import a barbershop quartet standard MIDI, resulting in “My Wild Irish Rose” by vpavlenko - Made With Hookpad.

As I play it on that page, I get no sound at all. If I play it from the Hookpad editor (2.25.10 on Chrome 107.0.5304.110, macOS Monterey 12.3.1), I get no sound. If I toggle mutes for voices in the “Band” pane, the sound for all four voices comes for a couple of measures and then disappears again. Can you please have a look and see, what is the root cause - my specific MIDI or generally the playback on four voices in Hookpad?

The playback works fine on a Bach chorale from Demo Tracks
