Hi, I'm sorry to intrude but I'm really finding it quite difficult to find the required amount of information to do this thing properly.

What I'm trying to do, is create a sfxplayer~.pd which plays out a stereo-sample. The stereo-sample (.wav) is defined inside pd by this:

-sfxplayer~ file.wav

This argument is then read by "something", and output into a messagebox that says
-read $1 channelL channelR

however, these channelL and channelR's are $0, i.e., specific to that instance of sfxplayer~ only.

I've tried to read tutorials, even a few books, and thought that renaming the array to $0-array1 would help, but no dice. So, since the sfxplayer~.pd consists of a "read <file.wav> <individualarray-Left> <individualarray-Right> and a tabplay~ <individualarray-Left> and another tabplay~ for <individualarray-Right>

I'm really starting to wonder what I'm supposed to name these things.
I tried passing a message (consisting of file.wav) to the read with it's $1, being replaced by the message sending a file.wav -- but to no avail.

If I create a $0-array1, it will say "0-array1 does not exist" or some such.

I'm so close, yet so far from being able to do this in a reasonable fashion. I thought having an inlet inside sfxplayer~ would allow me to patch the inlet's data (a message being banged from outside sfxplayer~) to the read arguments, but to no avail.

What am I doing wrong and why cannot I seem to comprehend how this is done?
Is it just a case of not knowing how to google for $0 $1 $2 pure data tutorials, or?

Edit: I now tried to put an inlet into the sfxplayer~.pd and connect that to the read -atom. When I banged the inlet, I got this:
$1: argument number out of range
usage: read [flags] filename tablename...

I "think" I got it to work.
I plugged the inlet into a symbol $1 and then plugged that to read $1 $1-L $1-R, modified the tabplay~ to play $1-R and $1-L for another instance, renamed the arrays to $1-L and $1-R.

Now all I really need to do is figure out how to trigger that from outside the sfxplayer~.pd. Maybe with a second inlet. not sure!

edit: got it to work (one bang (loadbang) to inlet1 to load the sample, one bang to inlet2 to trigger the sample)

Esa,

I made some small modifications to your patch. This version loads the sample when the object is created, eliminating the need for the first inlet. Now you can simply bang the single inlet to play the sample as soon as the object is created. I also added the -resize flag to the read message you're passing to [soundfiler]. Hopefully this helps you out.

Hi llorona! I finally built up enough courage to try this out. I've saved it as sfx2~.pd and am experimenting with it. It does everything exactly right! Thank you very very much

I really like the fact that it's even tinier than the 909 bytes
I got it down to 767 bytes by kinda moving stuff closer to eachother, so here is the final version I'm going to use from now on

I forgot to mention... you can replace the GUI arrays with http://www.pdpatchrepo.info/hurleur/llorona-sfx2~.pd

Well, there's no hard and fast rule. Certainly you can build EQs, mixers, etc. with Pd and use sliders, etc. to input data. However, from your other posts it seems you're developing for some smaller platform like Raspberry Pi or a game engine. In that case you'd want your patches to be as efficient as possible.

I'd definitely recommend getting rid of GUI arrays in favor of

Ok, returning back to this - I'm now attempting to load two wavefiles like this:
sfx~.pd drums/kick1.wav drums/kick2.wav

$1 (drums/kick1.wav) is processed via
inlet load
|
symbol $1
|
read -resize $1 $1-L $1-R(

so far, so good.
But if I put a symbol $2, read -resize $2 $2-L $2-R and soundfiler, and make two copies of $1-L / $1-R arrays and rename them to $2-L $2-R, it says "argument number out of range".

is this a case of me having to modify the script so that I bang a list to an inlet and the second entry is $2, or..?

[symbol $2( takes the second item in your list, and converts it to a symbol. so, for all intents and purposes, the INPUT of [symbol $1( and [symbol $2( is different, but they both OUTPUT a single symbol.

SO, in both cases, you would just use [read -resize $1 $1-L $1-R(

ie/

symbol $1
|
read -resize $1 $1-L $1-R(

symbol $2
|
read -resize $1 $1-L $1-R(
