[PD] Extracting textfile columns for audio

[Derek Holzer]

A more workable solution might be to use the IEM matrix object set, 
which is designed for exactly this sort of tabular data. I hacked 
together a pretty good preset saving system a month or two ago using 
them. You might have to format the txt file you are using a bit to get 
it to load, however. Check 5.reference/iemmatrix/matrix-help.pd (at 
least on Extended) for details.
