JJ OS2 universal adjusting in Step Edit possible?

is there an easy way in JJ OS2 to edit all the notes in a sequence (e.g. adjust the velocity of all the kick drum hits) at once?

I've looked all over for this in the manuals and have always ended up having to do each one individually, then again maybe I'm missing something really obvious here...

thanks to anyone who might be able to help

yeah, read about Seq Edit (mode 13) in Akai manual. You can manage velocity of all notes at once in there and many other things.

I see now, didn't occur to me to do it in Mode 13
much thanks
