Sorry...I forgot to add list address.

(in older pd's i would have used zexy's [tabset] instead of manually unrolling the list and writing the data with [tabwrite]; you canalso do this with plain pd)
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 ;-) Attached is the new patch. 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. as for iemmatrix, isn't it part of pd-extended? i will put a binary
online today....
I would like to take a look at iemmatrix. Please, tell me where I could find the binary for win32. Saludos! -- Raul Diaz Poblete ************************* [EMAIL PROTECTED] Ciudad Real [Spain]
