use tabread4~ with a soundfiler, array and phasor~
The output from soundfiler is the size of the audio file, the phasor~ multiplies this with a value between 0 and 1 to create an index for tabread4~ to play at the speed of the phasor~ frequency

use deken to install the iemgui library to your externals directory you will also have to add iemgui to your startup preferences

@ddw_music is right!
@cfry I didn't read your question properly, you should turn your subpatch into an abstraction then each instance will have a unique feedback loop using the $0 prefix

this should work

Here is a way to convert rgb to struct colours
rgb-struct-col.pd

I don't think cloned objects are expected to be visible at the same time, as they are addressed by an index $1 or "all" (I may be wrong) and made visible with [vis index 1( .
What I had in mind was create the object with creation arguments and address those.
I found it difficult to explain in words so I created this demo
Where we create the object "player" with $2 as the x position and with the creation arguments obj-$1 (where $1 is an appended number) and $1 this time representing the colour (and would be $3 if I wasn't being lazy)
Now we can send to the individual players as ob-1, ob-2, ob-3 etc
create.zip
I hope this helps

@RayManiac, sorry about that gifwork.pd was looking in the local folder "iemgui" which does not contain the iem_image.dll or the brushed-2.gif.
Replace it with this one
gifwork.pd

iem_image in iemgui allows transparent backgrounds, still gif only
A while ago I made this dummy for the hell of it as a test for a Knob object
I had a problem with z order and the gif have to be the actual size.
The background and knob faces are gifs

gifwork.zip

as your playlist element is an abstraction, you could add each player using:

@RayManiac This will do the job, I think
