Here is what i think
i think it's an issue with volume together with the lowpass.
The frequency that the lowpass is hitting is a critical frequency.
Try to slowly automate the volume less hard as it reached the critical frequency.
maybe you can balance it with a little less volume on all.
And afterwards limit the song this works for me very often.
Good Song good start. Make it a little longer
9/10 5/5
Please return the favour on my new song!
