Hey all,

Im working on an interactive algorithmic composing patch using markov chains, based mostly around the tutorials on http://algorithmiccomposer.blogspot.com/.

Im trying to get second order Markov Chains working, and there is only a tutorial for max. I need an object to make a list like so…

With an example input of 1 2 3 4 5 6 7 8 9

I need an output of this…

1 2 3
2 3 4
3 4 5
4 5 6
5 6 7 etc

This is what the 'zl stream 3' object is supposed to do in Max supposedly. What object do i use in PD to do the same job? Or is zl stream available for download?

Thanks

[zl] is included in Pd-extended, but, yeah, it doesn't seem to support stream. But it's not difficult to make with the

objects. The attached abstraction should work the same way. Give it an argument for the output length. You can also change the length with the right inlet or clear it with a [clear( message in the right inlet.

For future reference, in addition to [zl], there are many abstractions for working with lists in the list-abs library (I couldn't find one that did stream, though).

Thanks Maelstrom. That may have gone over my head slightly! As im a bit of a beginner with Pure Data. If I show you a screenshot of how I was trying to use zl stream. could you explain how to implement your attached patch?

Although I also just realised my $3 object isn't connected properly either! So disregard that
