There is [oreceive] object in iemguts lib that supports a numeric argument for response order.

OK Thanks it works now, after I (re?)installed unrar on my ubuntu machine....

Hello, I cannot open the .rar archive... fatal error

Regarding the video above, there was some changes introduced with latest pd versions to activate intelligent patching :
https://lists.puredata.info/pipermail/pd-list/2019-06/125403.html

The following video reports actual behaviour with latest pd versions (0.51)

you have to press shift in order to activate those features when you are connecting objects.

You can check my sinesum abstraction :

(from my pdr lib, inside inst_tabosc.pd ) https://github.com/jyg/pdr.
The sinesum is computed in signal domain (right window) using ifft~ object, every time a message changes the harmonic content (left window) in $0-harnonics table

FYI, I just changed the code, with a version that doesn't modify the pd-core. It's a bit more tricky on the patching level, but this way the pull request has more chances to be accepted.

@gmoon Great to know it works. Still to be fixed : number2 boxes.
Another cons of that fork is that I had to modify the source code of pd (and thus libpd) and Pierre Guillot cannot accept such a pull request on his project (what I can now understand after discuting with him). So it cannot be integrated this way into the main Camomile package, which means it needs to be compiled independently of official Camomile releases. And I cannot compile plugins for Windows or OSX.

I don't know...
I'm testing on Reaper 64 for linux. lubuntu 18.04.4. LTS
I cloned the camomil repo, I added vst2.x headers, I reconfigured with projucer for targetting vst2 (native) target, that's all....
Maybe removing image line in TestCamomile1.0.7.txt ?
