Apparently, the only known client supporting this feature is ardour (CVS) and so I had not yet tried it. Are there plans to include this functionality in PD? If so, any time soon?
hm ... possibly i'll look into the jack part of pd sooner or later in order to adapt it to the callback-based scheduler in devel ... i could have a look at that, too ... but at the moment it's very low priority ...
cheers... tim
