name param in piano rolls

[Antonin]

It took me a while to understand the
<piano roll> parameter :
at the end : next grid line

I know I'm being fussy here but " next grid colomn "
seems more appropriate to me or even better :
" next grid section " for it seems what it's doing

or not...
enjoy your day
