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

@KMETE This...... random_shuffle_cart.zip ... should work. 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.

@whale-av I'm getting those errors :

Any idea what is wrong with my patch?

1685864476416-main3.pd

btw- is there an object that output random numbers without repetition? same as urn in Max?

@KMETE For vanilla Pd you need to open cart5-vanilla.pd.
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....
David.

@KMETE I did not implement the file playing, just the random file stuff but I think this should do you assuming you are using a somewhat recent pd. 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.
rnd-file.pd

Thanks for suggestion!
I use urn pd version and it works fine!!

Small question - sf-play~ cannot read mp3 files?

for some reason the object [file] is grayd out on my pd on my Pi. Where can I download it?
my pure data version is 0.51.4

@KMETE You need 0.52 for [file] and as it is built into Pd it cannot be added to 0.51 unless you can find some external to do the job.
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?
David.

this is how you can change file names in gem and vanilla - if you name them with numbers its very easy you just plug the random number into $1.

@whale-av What is the latest version PD for Raspberry pi2?
I re install pd on my Pi2 and the version I got is 0.51.4

@KMETE RPI2 is 64-bit so you should be able to install the latest Pd...... but if there is no package for your OS then you will have to compile it...... which I understand is easy in Linux.
First on the list here for compilation...... https://puredata.info/downloads/pure-data ..... if there is not a good package further down the list.
