in other bemani emulators like mixwaver for beatmania there s always the option to play a track and slow to learn it, is there some option to do this in fof `?

i am searching and searching for a mod which allows to play tracks at lower speed in order to learn them.
do u know some tricks how to slow donw a track a bit?=

where do i have to enter the cheatcodes like "fastfoward" ?

is there some oppurtunity to slow the track down to learn the very hard part of it like in other bemani games.
in beatmania there was always the option to play the track in slowmode ( i think 60% and 80%speed)

is the tapping possibility (hammerons & pulloffs) disabled in this mod ??
