Hello, thank you for the quick and helpful replies.
Maybe I am wrong but I think something is wrong with vline~. The triangle wave in C04.control.to.signal.pd sounds and looks corrupted. (see attached pd file).
But I think I get the idea of the time tagged messages.
Would vline~ also take more than 1 message per audio block? I mean would it be possible to generate an message stream with a periode smaller than 64 samples and vline~ generates ramps between them? I tried it and it seems only one message per block is taken, I guess the latest one, but maybe vline~ is buggy.
greetings,
erik

See also the "vline~" object (starting in Pd 0.37) shown in doc/3.audio/examples/C04.control.to.signal.pd ... this can give either sample or linearly-interpolated sub-sample
accuracy.
A description is in chapter 3 of my "book": http://www.crca.ucsd.edu/~msp/techniques.htm

Hello, I am a pd newbie. I just read the manual with great interest. I worked
much
with reaktor so I am very interested in the differences between pd and reaktor. One difference is the time accuracy of the message processing. In
reaktor
messages (called events) have a time resolution of one sample instead of
64
in pd.
I read in the manual under 2.4.4: "You may wish to use block sizes
smaller
than 64 to gain finer resolutions of message/audio interaction, .. "
I tried that without success. I started from the the following audio example: "73.control.blocksize.pd". I added a metro object in the
subpatch
where the blocksize is reduced to one sample (block~ 1). The output of
the
metro is triggering an envelope with a short spike. Unlike the delaytime
of
the feedback delay in the example patch the time gap between two spikes cannot be set below 64 samples. I attached the file. I am using pd
0.36-0
under winxp. Maybe I am doing something wrong? Maybe there is an other solution to
that.
thank you and regards,
erik
