Trouble setting EQ

[Cal Mack]

 Good day
I purchased Rocket player a wile back and like it.
I am although having trouble with the equalizer settings. I can't figure out how to set it so it is the same for all songs. Sometimes the EQ icon on the top has a + sight above it and sometimes not.
It seems if I go into the EQ with the three dots beside the song playing at the bottom it seems to show the Active EQ and sometimes it shows a preset.
And some times if I set the EQ a window pops up and says the specific setting is attached to 1444 songs. But then if I go to a different song it shows a different preset.
I would like it to be active on all my songs
I am sure I am not doing something right but can not find any guidance/ tutorials on line can anyone help?

Using Version 5.16.70

on a Moto G6

Thanks

Hi,

Thanks for reaching out. I believe you also emailed but I haven't heard anything back. Just wanting to respond here in case you did not receive my email.

To easily apply the same EQ to all songs, go to your Folders tab and select the top most folder that contains all your music. Then long press and select Set EQ. There, you can select a preset to apply to all of your songs within that folder.

Let me know if you have any trouble.
