@ pp2007.pt: thanks very much for this.

@ skatias: I had the same problem and was able to overcome this by adding the hexloader library. After that, mtx_*, mtx_+ etc. should be working.

hi there,

I've got the same problem and found an object called mtx_phon_curve (from the iemmatrix library). It looks as if it is the right thing to use but I got stuck when I tried to implement it in my patch. Any suggestions more than welcome!

cheers!
