[NTG-context] Parallel texts: verse with blanks between stanzas via tabulate

Hi, I need to typeset two poems side by side. Usually, I use the tabulate environment for typesetting parallel texts. However, for poems this does not quite work as tabulate does not seem to allow blanks between the stanzas. See MWE below. Am I missing someting? Is there a better way to achieve this? Best, Denis %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \startbuffer[lines] \startlines[after={\blank}] this is a poem with two stanzas \stoplines \stopbuffer \starttext With a blank between the stanzas: \getbuffer[lines] Without a blank between the stanzas: \starttabulate[|p|p|] \NC \getbuffer[lines] \NC \getbuffer[lines] \NC\NR \stoptabulate \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
