Hi all (and probably most relevant to @jancsika),
I noticed today that Purr-data 2.13.0 systematically crashes when I try to save a patch with an [mknob] in it. Counts for patches that used to work with prior versions, as well as empty patches started from nothing with only a [moonlib/mknob] in it ("Save as" opens the window, but the actually saving crashes and the .pd file is 0b big). I seem to have the exact same issue on OpenSuse 15.2 and Debian 9.0 with the packages hosted on OBS (the Opensuse one says

$ > purr-data -version
Pd-L2Ork version 2.13.0 (20200802-rev.70066071)
compiled 12:00:00 Aug 24 2019

Not sure if it is a real bug that I should have reported to Purr-data's Gitlab page, if it is known already,or if I should use another knob or anything?

It sounds like a regression. Please report it at

@zigmhount hi, I saw your post about the knobs, did you find any other knob that actually works in purrdata? thanks

@mtdr2012 Hey, my bug report seems to still be open: https://git.purrdata.net/jwilkes/purr-data/-/issues/672 but maybe you can help solving it over there
I've moved from Purr-data to vanilla a couple of months after that issue so I can't really help anymore, sorry ! I'm focusing less on the UI now, so whenever I need a control for a knob I just use a centered hslider instead.
