Solace mask different sound in custom compared to main store titel

I started listening to AEON st1 two weeks ago. Yesterday I also listened to a fairly new custom. They are both in solace mask but for some reason they sound different.

I listened to the custom first and got the impression that it sounds quite “busy”, a little bit aggresive, nervously trickeling. When I listened to AEON afterwards, it was so calm and serene that I almost thought that I accidentally played the custom in 2x speed but I didn’t.

I don’t think that I experienced this before with other customs. The reason might be that this custom is really packed: 3 cores, 2 essence, 5 synergies, 20 modules in total. I’m already thinking that I’m going to reduce the density with a new custom.

But anyways, did anyone else experience something like that? The solace mask of major titles sounding more calm and slower than the solace mask of a custom?

Are you sure it sounded differently?
Or did you just feel it differently before ase of the density?
Because there shouldn’t be any difference in the mask. Just yesterday I got a new custom and it sounds absolutely like any other major store title.

Or did they miss to add the solace mask and you got the leagcy one instead?
