<br>with recent versions of pd, using [list] is definitely a good choice<br>(doesn't require any externals)<br>how have you tried to dump the data into a table and why did it not<br>work? (in older pd's i would have used zexy's [tabset] instead of
<br>manually unrolling the list and writing the data with [tabwrite]; you<br>canalso do this with plain pd)</blockquote><div><br>Finally I have made a patch to store video data into tables (R, G and B tables) with list and tabwrite. Sorry, but I got confused with list objetcs (working very late at night isn't so good ;-)
<br>Attached is the new patch.<br><br>But now I have 2 options: to work with tables (reading tables values with tabread and manipulating this values) or to work without tables, manipulating lists directly to extract each value I need. What's the best option in terms of computational effectivity? (I use a lot of data which require a lot of cpu, so I need to minimize computational cost). I will use this video data for audio synthesis.
