Dynamically creating arrays
"graph" is just a [pd] sub-patch with the Graph on Parent option turned on. This is like an empty container where you can put an array into (using the "put array into last graph" option) or anything else you want.
As far as I know, there are three (plus one) option for storing arrays:
-
"Array" from the put menu. This stores the data in a graph, which you can draw manually.
-
the "table" object, ie. [table sound1]. This is basically an array but in a closed sub-patch, saving on CPU power as discussed earlier.
-
the new "array" object in Vanilla 0.45 and higher, ie. [array define myarray], distinct from the "array" in the put menu. This functions more like [table], but has the additional functionality of [array get], [array set], [array random] etc. (see the helpfile for information on this). Like table, if you click on [array define], you'll see the graph, but you won't have access to the familiar options (points, polygon, etc).
All three of these objects can be written to and read from using the same tabread and tabwrite objects, and there's no difference between them that I know of in terms of playback. I think that the put menu "array" is the only one that will allow you to save the contents in the patch, though.
It might seem strange that there are three versions of roughly the same thing, but the explanation is probably that they were created at different times. Instead of replacing and updating old and obsolete objects, which tends to render old patches as incompatible, Miller likes to make new objects and leave the old ones in place.
The "plus one" method is to store arrays in data structures, but this is pointless for what you're doing because a: it's very difficult and b: these arrays can't be read and written to by tabread/write objects.

Finally:
Albert Gräf added an AUR package here
"This always builds from the latest git sources and can be used as a drop-in replacement for the pd-l2ork or pd-l2ork-git package. Just run yaourt -S purr-data-git and you should be set (be patient, this package takes quite a while to build)."

Referencing argument array names in PD subpatches / abstractions?
Consider the following trivial patch (testing on Pd 0.45.4 on Ubuntu 14.04):
In it, I have a [pd mysubpatch A]. As far as I remember, the A is now an argument of/to the subpatch, in particular it is the first argument - and references to $1 inside the subpatch should expand to A.
So, I've decided to place an array inside the subpatch, and call it $1-array, similar to how in abstractions, arrays are/can be called $0-array - except there the $0 doesn't expand to any arguments, but instead expands to a random number (Dollar signs in objects and messages | PURE DATA forum~). My expectation is that the $1 in my case would expand to the first argument, A, and thus the array name at instantiation time of the object [pd mysubpatch A] would expand to A-array.
The idea is thus to be able to put multiple subpatches in a patch, and control their internal arrays' names by supplying unique arguments. So, I try to copy/duplicate the [pd mysubpatch A] into a [pd mysubpatch B], expecting its array would ultimately be called B-array. So far so good, because I can do this without any problems.
Now consider a slightly more complicated case where I also have a tabwrite~ in the subpatch:
Now that I have [tabwrite~ $1-array] referencing the $1-array in the subpatch, as soon as I turn on DSP/audio, I get a ton of warning: $1-array: multiply defined messages. As I don't get this message when I have only the $1-array in the subpatch, I'm assuming it is not the logic in naming the arrays $1-array via subpatch arguments that is the problem, but instead it is the reference in the [tabwrite~ $1-array] which is causing the warning message.
Note that exactly the same happens, if I save the subpatch as an abstraction mysubpatch.pd, and use it as two objects [pd mysubpatch.pd A] and [pd mysubpatch.pd B]:
But then, in this case, how would I reference such a subpatch/abstraction array, named through an argument, from inside the subpatch/abstraction itself? Note that I need fixed, explicit, known names of arrays, so a workaround like $0-$1-array wouldn't work for me, since the $0 would expand to a random number, which I in principle do not know from the outside (and I'm not sure $0 even applies to subpatches).

Install PD extend on Ubuntustudio
I just installed Ubuntustudio 15.10 Wily Werewolf 32bit on a thinkpad and I am trying to upgrade PD to extend. I am fairly new to linux but it seems like the instructions on https://puredata.info/docs/faq/debian fails.
This is the log from executing the commands. Any suggestions and help will be appreciated
