hello Hein,
if you meant effect type, effect depth, brightness, harmonic content, ... for R1, R2, R3, Left, Accompaniment, Song, ..., it everything can be saved in registration memory (see page 144 of the english PDF documentation).
If you meant you own effect type - they can be stored in 10 user effect and saved in "Disk/SCSI" Menu to the FD or HD.
Hope this helps.
Marek
