How Does One Create This Sound

alright. this is my first time posting on this forum and it’s good to be here so hi.

what I would like some help with though is how the changes were created in this song in terms of the main synth.
the actual synth sound is not too hard to make but i’m lost at how the changes in its sound a lot of the time are created. i thought some kind of automation of filters or pitch bending but haven’t been able to create anything which sounds exactly like it. so if you can somehow work out how to create this sound it would be cool. from the start till about 1 min in illustrates the sound well enough.

any help would be appreciated

oh and there is the download link for the song


it’s a combination of band-scoop filter. sweeping that. and phasers. everything else is just pitch bending.

thanks . will try that out
