HI!

Quick version:

My folder structure:
/mother-patch.pd ( main pure data patch first loaded and running... )
/patches/1/main.pd
/patches/2/main.pd
/patches/3/main.pd
...

How i could open /patches/1/main.pd triggered by some action in the mother-patch.pd?
How i could close /patches/1/main.pd triggered by some action in the mother-patch.pd?

Long read

I'm attempting to clone the Critter and Guitari organelle ( link ).
This instrument is basically a computer running libpd and running very cool pure data patches
You can read more about my project here ( link )

I have a mother pure data patch that it's first loaded when the device is on, this patch is doing some [send] and [receive] operations related to the knobs/keyboard/volume/led and it should be also managing the loading ( opening and closing ) of the child pure data patches ( mentioned above ). This child patches are receiving the actions from the mother patch.

If I open the mother patch and the child patches manually, everything works fine. But now I need to OPEN this CHILD PURE DATA patches with a object within the mother patch.

I've been testing [open] , for opening the main.pd of the child patches but it does not work.
I've been testing [pd] , for opening the main.pd of the child patches but it does not work.
I wouldn't like to modify the original organelle patches.
I wouldn't like to end up loading all the patches using [pd ...] and inserting a [switch] object inside every main.pd file in the patches in order to enable only the dsp of the desired patch.

It would be perfect If i could have a folder with all the patches and load them within the mother patch with some kind of object. And I would also want to be able to CLOSE the pure data patch and open another ( changing patches... )

Every little and big help woul be MUCH APRECIATED!

THANKS!!!!!!!

@deframmentazione-geometrica Hello......
it looks as though it should be an "f"
Triggers will send known Pure Data message "types" in the "right to left" order from their outlets..... and also convert them to "bangs" where there is a "b".
The types are:-
a ..... anything (useful if you are not sure)
b ..... bang
f ...... a float (number)
l ....... a list....... i.e. list 1 2 3....... or woof 4 5 6
s ...... a symbol ...... i.e. woof
p ..... a pointer ...... to a scalar in a list
so the message you see is saying that trigger cannot use/ does not know what "i" means....... and so there is an error in the previous post....

Hi David, thank you for this clear and useful answer.

I am accomplishing something similar, in a different way, so I don't have to use full paths. Chek out pdpi. In MAIN.pd I dynamically load a patch like this:

When it receives a float message on programchange, it dynamically loads the patch, then sends a synthetic loadbang message (dynamic loaded stuff doesn't trigger loadbang.)

To wire things up, I have a catch~ L, catch~ R hooked to dac~ and s control, and s note hooked to ctlin and notein

After what it has been said in this topic maybe I'm going to ask obvious things, I'm not a progammer so be patient.

Well, I want the children patchs open randomly through a first order markov chain. I found a patch with a markov chain matrix that works well changing simple frequencies mother markov 2.pd . Now, how can I write the children patchs list in the message to load the patchs? I did some attemps but I got the simultaneous opening of patchs or the crash of pd. Any suggestion? Thanks

@deframmentazione-geometrica Hello again! I am not completely understanding, and I don't have [markov~] on my system so I have had to guess the meanings of the messages. Is this anywhere close to what you might need?
mother_markov_2.pd
I don't understand what you mean by "children" in your patch, as you are not opening any "sub-patches" that I can see......... so I have just built a small system to bang in the messages randomly and after a random amount of time....
I hope it makes sense......
David.

@whale-av Hi David, thanks, it makes sense... Now I can open randomly the sub-patch and this is already nice.
Going a step further and following your patch I did some clumsy attemp to make the markov matrix "drives" the choise of the next sub-patch to open http://www.algorithmiccomposer.com/2010/05/algorithmic-composition-tutorial-markov.html.
without anything coming of it mother markov 2.1.pd

@deframmentazione-geometrica Hello Matteo...... what drops out of the outlet(s?) of the [markov~] object?
Put a [print] object and connect it to the outlet to see what it is sending. Look at the terminal to see the output of the [print] object...... and that will give you some clues about how to trigger your patches...
David.

@whale-av Hi David, in the end I changed my mind along the way and I did this mother markov 3.pd, using the most common and understandable method I found on the web using random and moses objects. At moment I abondoned the idea to make it with markov object and transition matrix.

Thanks for your help.

Hello,
I am trying to implement this. I am curious though. Ofelia does not seem to be working when I automatically open the file. Using a master patch. Any help?
