.crs/attack revert to dyanmic scroll speed over fixed time?

Hey all,

So i understand how to change scroll speed in attacks/mods in .crs files with something like:

TIME=15.22:LEN=0.19:MODS=*10000 2.00x:

I know that after 0.19s it would revert back to the user-chosen x scroll speed over a time based on BPM (one beat, i believe?).

What's the syntax for returning to the user-chosen x scroll speed over a custom time? For example:

TIME=15.22:LEN=0.19:MODS=*10000 2.00x:

TIME=15.41:LEN=1.00:MODS=*1 {return to default}x:

Not possible in .crs; unsure if attacks can do it (wanna say no).

Certain lua can give you those results though.

yeah that's what i was afraid of. I may try to explore the .lua route once i get more course and lua savvy.

Thanks anyway!
