Hello everybody!

This is my first post here on the forum. I've recently discovered this incredible tool and Im getting
quite euphoric about that
SO let's start whit my first problem: Im desperately trying to create an abstraction that accept 1 variable that form the name of an array inside the abstraction.
i've used the $ sign inside the abstraction and declared in the parent patch as {MIDI_REC_TEST 0 0 1). This is how it look:

As you can see the $3 still remain in the name of array. What is the right way for doing that?

Regards guys

Dollar variables are interpreted by PD according to the creation arguments, but they re not renamed on the screen. Hence you will never "see" the renamed object. It sounds to me like you've done everything correctly.

Thanks for your response LiamG, but what if I would like to create an abstraction that have unique Name for each array?

My problem is that I'm creating a parent Patch with different declarations of the this abstraction, but all of them are writing in the same arrays! Here is how the abstraction is done:

You should use $0 that is a number specific to the instance of the abstraction.

Yess, it's finally working!! Thankss a lot!!! I'll soon share my new abstraction on the forum
Is there any particular tutorial or reference for $ sign and for array dynamic editing that you guys can suggest???

Yes in PD, the patches 13.locality.pd and 14.dollarsigns.pd from the menu Help/Browser.../2.control.examples

Is there any way to resize the dimension of an array using messages or any kind of not-manual trick?

yes, send "resize" with the size in samples to the array, see 15.array.pd

I do followed that example but that not seems to effectively change the array size because when I check the array size r-clicking the array the value doesn't change! I want to sample a MIDI source for a generic time writing the value in an array, so I'd like to change the array size dynamically to fit with all the value necessary, but the graph seems to remain always the same with this command! What am I doing wrong??

Hey guys I finally Solved! My problem was that I was again using $0 in the wrong way , This was the wrong message
[;
$0-Pitch resize $1]

but in this case the message box seem to doesn't recognize it as the patch constant. Then I tried to send the $0 value with a pack and float box in this way:
|loadbang|
|
|f $0| [120]
| _____ |
|pack f f|
|
[;
$1-Pitch resize $2]

AND THAT FINALLY WORKED

But I can't explain why

Yeah $0 doesn't work inside message boxes, annoyingly. The solution you've given is correct. Another options is:

[4
|
[resize $1(
|
[send $0-Pitch]

I think that $0 is considered as the first default argument of a patch. Using it inside a message would lead to confusion about the behavior of $ inside messages, I guess...

You're right that there are two different $ systems, and this can get confusing. But $0 has no function in messages, so the conflict would only be superficial. L2Ork already supports $0 in messages without any trouble.
