Hi,
I am getting dsp drop-outs when I resize a table (say a size of 200000 or so) if a tabread~ object exists reading from that table, even if I am not listening to the output of the tabread~. Even if the tabread~ is in a switch~ed off subpatch/abstraction.
Does PD recompute the whole DSP chain whenever a table (with one or more tabread~ reading from it) is resized?
I'm talking about resizing tables by sending them a [resize( message.
I tried to isolate it in a simple patch but I couldn't reproduce it. But I think the only difference with the patch where I am experiencing this is the complexity of the global dsp graph, that's why I ask if the dsp graph is recomputed.....

yes, the dsp chain is recreated ...

sure ... the more complex the dsp graph gets, the cpu time to resort the graph increases ... of course allocating memory from the underlying os is not a lightweight operation, either ...
in pd, you shouldn't try to resize / load / store tables during a performance, except you like the sound of the audio dropout ... if you need this, i can only suggest to use another program ...
