Traktor Pro 4 Stems sometimes play muffled.

OoA7

Hi, When playing a stems track in Traktor Pro 4, on a MacBook Pro M1, the track loads and plays correctly, but will suddenly play muffled, and the visual sound wave will appear blurred.

For example, this is how the track in Deck A should look…

But here is the same track playing muffled…

You can see that only the drums sound wave is correct. When loaded, all the sound waves look correct. It's during playback that the issue occurs.

Does anyone know why this is happening and/or more importantly, how to prevent it from happening?

Thanks in advance,

Mark
