hi everybody,

i'm currently working on a groovebox-like beat tool and i'm struggeling with the whole save thing.
does pd provide any object or message to save / load a path of a .wav file, so that i can link all my samples in a preset?
it also would be nice to pack everything in one preset file together with my other tables etc. which also should be saved..

thanks in advance

Okay, I see. So let me explain a bit about how this approach works, because I'm realizing now it may not be entirely clear. When you use these abstractions to make a "dump" method in an abstraction, what happens is each parameter gets sent out with its [save.me.mmb] name and value. Now, when you collect all of those parameters in a single [save.me.mmb] outside of the abstraction, the name and value pairs are all stored. When they get loaded, they get spit out, again in name and value pairs. You need to [route] those pairs in the abstraction to wherever they need to go. Right now, you have the [route], but it's not doing anything.

oh my, this one is quite obvious. thanks again for the help..
one last thing would be the saving in relative paths (the file symbols), so i can use my presets on different computers / os. openpanel alsways puts out the absolute path, even when i switched to the patche's dir where my samples are in.

Assuming the samples are all in the same folder (let's call it "samples"), and that folder is in the same folder the main patch is in (which is the best way to do it if you are passing the patch around), then the simplest way would be to use [declare] to add the samples folder to the path when the patch loads:

[declare -path samples]

Put that in your main patch. You might have to save and reload the patch for it to take effect.

Then, when you call up the sample using [openpanel], you can use [splitfilename] to get the file name only. You won't need to keep the path, because Pd will look for it in the samples folder when you load the file into [soundfiler] or whatever.

usually i have some subfolders like samples/kicks, snares etc. but if it's the only way i could get used to it.

i stumbled upon a new saving issue - in my patch there are 2 tables which need to be saved in the same preset file together with all the other parameters etc. i tried to add the routine like in the attached patch -> error msg output (addcomma) and the table gets saved and loaded. the other parameters also appear in the preset file but don't get loaded.. any idea?

forget about the previous post, i found the bug..

It's not the only way, it's just one way. Keep in mind you can add multiple [declare]s, so you can have [declare -path samples/kicks], [declare -path samples/snares], etc.

You can also do some list processing to try and keep the "samples/kicks" part if you want:

[openpanel]
|
[symbol2list]
|
[t l l]
| \
|

| \
| [- 3]
| \
|
[list2symbol]

Actually, check out this patch I just put together. It will give you a relative path if the path given is contained in the same folder as the patch. Otherwise, it will give an absolute path.

boom! that's what I needed.. I just shared my little project in the patches section - have a look and tell me what you think.
