@lacuna Thanks again, and sorry I'm not more literate on this, I'm self-taught and picking it all up slowly as I go. I'd love if anyone has recommendations for learning resources so I'm not just patching stuff together (pun intended).

I actually ended up changing my approach, as it was somewhat challenging to generate te kinds of results I wanted. Instead I have used the list-dripslow object from the list-abs externals library to serialize a long list of variations I have created myself.

Thank you @lacuna for sharing this patch. I built it according to the image you sent and it doesn't seem to produce all of the numbers before permitting a repeat:

For example, the run of numbers 1, 0, 2, 3, 2, 0, 1. Maybe I'm just getting confused- thinking about it, it's possible for any specific number to have up to 6 other numbers between them, if they were randomly selected as the first in sequence of four, and then in the last in the next sequence of four.
Thank you! You are all waaay ahead of me on this.
@porres I should probably learn how to get externals from github. It's a little complicated as in this instance I'm running the patches I'm building on 3 raspberry pis all connected via wireless internet: I often find it challenging to build on my laptop and then migrate the patches smoothly onto the pis.
Thank you for your help everyone, I really appreciate it.

Thanks to all who have already replied here! Apologies I didn't think to specify this in my original post but an important detail here is that I need to make sure that no consecutive files play ever. With many of the objects helpfully suggested above, there is a risk that the last number in a random sequence will be the same as the first number of the next random sequence. I understand this has already been discussed above but seems worth mentioning here.

Sadly the example random-wo-repitition.pd produces occasional repeats when it restarts the sequence.

Something like the 3rd argument on motex/shuffle would be ideal. However, I am using pd 0.56.2 on a raspberry pi 5, and motex is not available to me via deken for this architecture.

@porres thanks for adding the hold feature to else/rand.u - I downloaded the latest else library and I don't think the external has been updated yet for pi/linux? I don't see the hold argument on the list in the help window for the object.

If this isn't going to be feasible on my architecture I think a good alternative would be for me to create a long list of numbers without repeats and prompt these in order with a bang: can anyone recommend an object that will do this and loop back around to begin the sequence again once it has finished? This would at least create the illusion of randomness, as I could make sure it doesn't repeat.

Thanks again to anyone who can help with this!

I suspect this information is somewhere in the forum, but if so I cannot find it. Apologies if I'm duplicating.

I want to build a patch to shuffle-play a number of audio tracks, with no repeats until they have all been played, and then start again with a new shuffled list.

I have already made this 'shuffle' subpatch to avoid consecutive repeats:

What would be the best way to build something that will shuffle numbers 0-3, then only allow repeats of any of these numbers once all of them have been produced? It would then need to begin again from the beginning and run indefinitely in this cycle.

Thanks!

Hi @porres

Thanks for this info. I would volunteer my help but I don't think I have the experience yet. I'm not actually sure where to start, although I did find an old youtube tutorial detailing the pd-lib-builder compiling process:

Thanks @alexandros

I haven't built an externals library before, but I shall give it a shot!

Any other advice gratefully received

@porres you may be able to shed some light on this? Thanks in advance!

Hello, again forum! I posted 4 months ago because I was having issues with else externals, which I was able to solve by building the latest version of PD.
https://forum.pdpatchrepo.info/topic/14839/else-externals-not-working-on-raspberry-pi-4b-running-pd-0-51-4

Now I am running into problems again. I have a new Raspberry Pi 5 running Debian GNU/Linux 12. I have built PD 0.55-1 and it is running successfully, but when I search for else externals library in deken is get the following:

"else": Found 0 usable packages (of 5 packages in total).
It appears that there are no matching packages for your architecture.

I looked on the github page for else and it says that "This version of ELSE needs Pd 0.55-1 or above.", which is the version I have.

I wonder if anyone can provide some advice? Not sure what I'm doing wrong. The only thing that is different from 4 months ago when I solved this problem is that I'm now using a pi 5?

Thanks!

@mod This is a nice patch, sounds good, although I see this is set up to load existing files: can you recommend a way to customise it so it accepts incoming audio as a live feed?

Thanks!

Thanks! Gonna check this out now.
