step edit external sequencing

hi there,
just a quick question:
am i right that there is no way to step edit an external midi sequence?

where is all the information of an external seq stored? and is there an onboard way to access the seq data (despite recording the seq midi into a daw or midi viewer)?
thanks in advance!

Maybe explain what you want to do. Right now I am not sure and would likely give bad advice.

Get the pdf manual, its in there and yes you can.
