Apologies for any delay getting back to you.

I downloaded about half the externals from the "find externals" page.

Also I changed the prefferences for the

"install extras to directory"

to:

home/computer/pd-externals

And I downloaded your two objects:

output~

inv

but it won't let me copy ad paste them into the home/computer/pd-externals folder, saying:

Extraction not performed

You don't have the right permissions to extract archives in the folder “extra”

How come i have downloaded all these externals and it still doesn't recognise "inv" or "output~"

Any help much apprieciated.

Thanks.

Just for reference the extra folder path is:

/usr/lib/pd/extra/Gem

@whale-av Thank you that is so helpful.

I downloaded:

https://puredata.info/downloads/extended-view-toolkit.

Where do I copy and paste the extracted zip files into?

Is it the "extra" folder?

Where exacty is the "extra" folder?

Many thanks again for all help.

@whale-av Thanks thats great.

Will install those libraries tomorrow and let you know.

Are there and other libraries that I should install?

Especially concidering I am hoping to learn 3D graphics and video/multimedia for live performance.

@whale-av I have read http://puredata.info/docs/faq/debian but all I get is this:

sudo apt-get install pd-extended
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package pd-extended is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Can some one help?

As for the Deken download:

Commencing downloading of:
http://puredata.info/downloads/deken/releases/0.4.1/deken-plugin-v0.4.1--externals.zip
Into /home/computer/pd-externals...
= 44%
= 89%
= 100%
Successfully unzipped deken-plugin-v0.4.1--externals.zip into /home/computer/pd-externals.

But then in the Pd window I get:

And I downloaded your two objects but where do I put them?
It would be better to install the whole libraries than just insert one or two at a time.

Thanks for any help.

Pd-vanilla appears in synaptic package manager but not pd-extended.

The book i'm learning from lists objects like:

output~

or

inv

Which don't work in Pd-vanilla.

How can I download pd-extended on Linux Mint?
