@Worik Excellent library but originally built in Pd Extended.... so it needs pretty much all of the libraries that were available at the time.
Most have been updated for 64-bit Pd but not every object and not for every OS.......

It is almost always possible to work around missing objects.

The easy solution is to find an older 32-bit RPI and install Pd Extended.

Otherwise upload a list to this thread of what is still missing once you have found everything available on Deken.
Some objects will be directly replaceable by newer externals that will have different names in other libraries.
Others will have had vanilla patch replacements built by users over the years and someone will try to help you out..... eg.....https://forum.pdpatchrepo.info/topic/14619/order-of-ops-confusion-troubleshooting-vanilla-demux-abstraction
Others might not be replaceable but might not be absolutely necessary..?

Edit...
This FAQ might well help....... http://gerard.paresys.free.fr/ARGOPd/ARGOPdFAQ.html
"How Do I Install Pd On Debian, Ubuntu, Mint GNU/Linux?" Solution2... about half way down the FAQ..

@EEight Ahha..... so I cannot log in because I am already logged in through the other domain.
Makes sense now..!.
David.

@jameslo Same IP but different domain.... I think it might be a NodeBB server backup copy with login disallowed.
David.

@Ulrike I cannot log in to the (evil ) one .. so not identical, but it seems to be a carbon copy otherwise.
I know that @Eeight has been thinking about updating the forum as the NodeBB version is ancient.
Maybe he has cloned it for testing?

forum.puredata.info is a subdomain of puredata.info and puredata.info is the Pure data info site I think run by Miller, so I think we can forget the "evil" moniker.
But unsure and will have to await a response from @Eeight
David.

@le26muko Yes....... https://forum.pdpatchrepo.info/topic/788/open-a-pd-patch
That thread also tells you how to make an abstraction or a sub-patch visible, which is I think what you are asking for...?
David.

@jamcultur Escaping the 0 seems to work, but I cannot see a way to preserve the message on reopening the patch.
This from I think @jameslo works.......... concat.zip
David.

@Ice-Ice ..... from the tombs of the forum...... shift_xor.pd
Fixed length of course..

@Jake-15m3 You might find some clues here....... https://forum.pdpatchrepo.info/topic/11850/explanation-for-lop-object-in-this-patch-requested
Some discussion and maths in that thread, and links from @seb-harmonik.ar that lead to posts showing the source code for such a low pass filter.

I can imagine that audio modelling could resemble fluid dynamics of an incompressible liquid so... ?
David.

@ddw_music Well you can change the font for the patch........ change font.pd ... but it doesn't help for the console or menus.

You can also set the same for your Pd in the preferences with a startup flag...... -font-size x

Pd boxes (messages, objects) are scaled to the font but arrays and graphics are not.
And it will likely make a mess when sharing too.
There was a discussion about setting the DPI for the OS I think, and then excluding all other programs but that is probably not satisfactory either.
Of course someone might have a better solution since the last time this was asked.
Discussion found so far...... https://lists.iem.at/hyperkitty/list/pd-list@lists.iem.at/message/D7Y2HW3X3IMYEAF2N7DY5GR2T3G2A6RQ/

I have noticed that sizes are sometimes different in different releases for windows so it could be worth delving deeper.
David.
P.S. just playing around with pdwindow.tcl....... I am sure it can be taken further.......

@nicolasdanet I like "noodle confusion"...
