[#tabread from] | | | [#tabwrite to]--' Just like vanilla's except you don't have to make a counter on your own (which was not drawn by Johannes in his example). replace 1024 by your array's size (or feed it in middle inlet). This is much faster than the vanilla equivalent because it only sends 3 messages in total instead of 3 times the number of elements. It's basically as if you could "compile" your vanilla message-system patch. For older versions of [#for], add a '1' argument as the step size ($3), because it didn't have a default value. ___ | Mathieu Bouchard -- Villeray, Montréal, QC___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
Re: [PD] Clearing and Copying an array
Hi Raffael, Keep in mind that copying between arrays at faster than audio speed may give the same kind of glitches you get when you use [soundfiler] to load audio into an array. For this reason I wouldn't recommend it during a live performance. My recommendation would be to either use several arrays which you can switch between, or make one long array and switch between active "zones" in the array for different loops. STEIM's LiSa live-sampling program takes the second approach, by the way... Best!
