For what is worth, I found out that feeding a pitch cv signal to a module like Befaco Rampage, or any other module that can generate a slew, and that can output gates of "Rising" and "Falling", generates very useful gates, whose period duration can be adjusted by fiddling the Rise and Fall time parameters of the slew processor.
In addition, I can send the gates of Rising and Falling to either a cv mixer or a logic OR module, to have gates for every pitch change.
A consideration about quantizers: some of them output "full gates", meaning that the gates last the entire duration of a new pitch, (basically like a midi note-on), and with those I lose the Release phase of any ADSR. This is why I prefer having control over the duration of the gates, independently.
