<![CDATA[play a random file on button press]]>I'm using Raspberry Pi and an Arduino to read button presses.

I have a folder with 10 or so WAV files.
I would like that when button is pressed a random file will be playing from the beginning to end. Only when file finished a new press will active a new random file.

How can I implement that with PD?

Thanks

The vanilla [cart5-vanilla] needs at least Pd 0.52 I think for [file].
You can simplify it maybe, especially if you give your wav files names 0.wav, 1.wav etc., but it will give you some ideas.

You can use [change] after [random] to avoid repeats, but need a mechanism to ask [random] for a new value when a repeat is rejected.
No time to look at your patch until this evening but someone will probably reply....

Added a toggle to delete the file from the list if you want it to never play the file a second time, wasn't sure if you wanted to avoid repeats or avoid ever playing a file twice.

In the zip I posted above cart5.pd was built with extended, and there are externals from the hcs and ext13 libraries that you might find available for Linux Pd 64bit.
hcs/folder_list and ext13/strippath
Or maybe it's a good time for an upgrade?

I re install pd on my Pi2 and the version I got is 0.51.4

First on the list here for compilation...... https://puredata.info/downloads/pure-data ..... if there is not a good package further down the list.
