@Liquidyzer This contains all of the patches below and a sample..... open sample.zip
The first example...... open_sample.pd
Basically "open" is just dropped..... you could put "list" instead, or "woof"....... or any symbol (try it if you don't believe me).
The "open" or "woof" says to Pd "this is a list" The message then sends a list of one atom....... "track1.wav" which replaces $1.
Without the "list" tag the next message box complains..... the $1 expects an atom from a list.
Yes, it's not obvious, but it is documented in many help files in the Pd installation.
A series of symbols and floats that starts with a float is automatically a "list".
So [1 woof 3( is a list and all the atoms are passed onwards and can be translated by $1 $2 and $3.
But [track1.wav( is a symbol........ not a list. By putting more than one symbol it becomes a list as with [open track1.wav(........ but "open" is translated as a "tag" that says...... this is a list....... and so is not passed onwards. "track1.wav" is passed onwards as the list.

You can do the same thing with [pack s]...... packing the symbol "track1.wav" into a list.
open_sample2.pd

You don't need to include $1 (track1.wav) in the array name, but it helps if you want to write many samples to many arrays, and know which one is which....... or using [pack s $0] you can get $0 into the array name as you wished...... open_sample3.pd

Thanks David, super detailed response, what I was looking for! I'll crack on with this and see how I get on

Thanks, Im actually trying to replace the open panel with a simple open xxx.wav. Ive added $ but getting error "expected float but got open".

Hi all,

Im trying to substitute an openpanel object for a plain open file extension (eg. open xxx.wav) but I'm having issues connecting it to the pack object below it as it is expecting a symbol. Can someone explain to me how and why there is a difference. thanks!

Another newbie query that I'm struggling with. I'm getting to the point with my pd on raspberry pi where I'd like to use some obscurer externals. I realise I need to re-compile them off the Mac versions so they'll work with my pi zero (arm6) but quick searching I haven't found any definitive instructions for doing so. Any tips?

Works a treat guys, thanks a million

I have a super simple audio delay that's been adapted to work with a eurorack module i'm making patches for.
There are gate inputs that can be assigned and i can create regular bangs from, just trying to figure out how i can get the delay to sync. Anyone point me in the right direction?
