Problems with Markov Chain

Hey! I’m pretty new to OM and Algorithmic composition, so this might be a really noob question but here I am.
I tried creating a Markov Chain analyzes with OM, based on this tutorial:
http://www.algorithmiccomposer.com/2010/04/openmusic-markov-chains-and-omlea.html

Well, everything was pretty similar to the tutorial, with the exception of the mf-info function. In the tutorial it has two inlets, in my OM it has only one. I looked at the documentation and it seems that I can create an optional argument to inform a track number. I don’t know if that’s what getting me the error, but everytime I try to evaluate the chain it gives me an error message saying “Error while evaluating the box ANA-MARK: Arithmetic error in < of ((60 0 214 58 2)(72 0 214 58 1)): arguments must be real numbers.”
I really couldn’t get what’s wrong with it so I’m here asking you guys to help me.
And again, sorry for this dumb question =P

Hi Lucas.

You can access the second input using ‘Alt-[rightarrow]’ on the box, to select one track. I beleive this will get rid of the error you see.

Forgive me if i sound like selling soap, but the Patterns-library provides a more direct way to analyze data to achieve markov-tables, and generate new data based on this analysis. Check the attached shot. Anders.

hello anders,

thanks for the pattern library.
I’m not being able to access the second input of p-markov-analyze. not with the previously mentioned alt-right arrow, nor with the usual shift->.
any thoughts? I’m on macOSXHighSierra/om6.12/patterns0.99.3
thanks in advance for any info,
perti

Hi Perti.

p-markov-analyze uses keyword args, so to add inputs, hit “k”, then click on the input to select which argument to the function you want to add.
