Dear list, i have a question regarding timing in Pd:
I understand that messages to tilde objects just get passed to the DSP tree within DSP blocks. How about the reverse? Found out that snapshot~ is returning the last sample of the last block during which it got banged. This is fine, since it is the sample value most closely to the output of the result. Now when i use the following setup: [bang~] | | [t b b] | | | | [timer] i get a minimum logical time of 1.45 msec (aquivalent to 64samples at 44.1 kHz) even when i use a blocksize of [block~ 32]. That makes me assume that the "sampling period" for an external process (such as an audio clock, represented by bang~) is limited to 64 samples. What is also interesting, is that i get the double value of 2.9 msec for blocksizes above 64, for example 65 and above. There are no adc~ or dac~ objects or any subpatches in this setup. So, with predefined timing objects (such as [del]), the resolution of the logical time in [timer] can be as low as a fraction of a millisecond, while non-deterministic events get sampled every 64 DSP ticks (or probably integer mutiples). All still confusing somehow, looking forwards to any answers! regards, Peter _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
