Does Cubase have a Paul Stretch plugin? If not, are there any third party plugins for Paul Stretching?
I don’t know what Paul Stretch is, but there is not Stretch algorithm with this name in Cubase.
I’d hazard a guess he means Paul’s time stretch http://hypermammut.sourceforge.net/paulstretch/
Quite interesting if you’re not familiar with it.
Google says there is https://www.kvraudio.com/product/paulxstretch-by-xenakios
