[PD] cosinesum vs sinesum in arrays
Dear List, not sure if I am getting something wrong here, but it seems that sending the message ; cosinesum array999 1 does something different (besides an obvious phase shift between sine and cosine functions) to the resulting contents of that table: the first partial on cosinesum seems to be the DC component, while the first partial in sinesum is the, well, first partial. Accordingly, the second partials have double frequency in sinesum as in cosinesum. Perhaps this is intentional, but was just wondering... best, Peter ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

The GUI can freeze if Pd is overloaded with audio computation on Mcintosh

There are a few things:
1) Weird treatment of the tk error window in OSX. It looks like
sometimes it causes an infinite loop, but I can't predictably generate
the error.
2) If I understand it correctly, the tk event loop can run into the same
problem the Pd audio dsp scheduler runs into with when you have too many
calculations per dsp tick. But it's worse with tk because it isn't
optimized for doing timely graphics updates in the first place. If you
are sending a constant stream of just enough data to the gui that tk no
longer has any idle time to update graphics, then you may get yourself
into a situation where tk never updates and you see a freeze.
Moreover, tk seems not to use its idle time very efficiently. I built a
recursive loop for the search plugin specifically to let the user
interact, cancel operations while building a search index. But you can
see how inefficient its drawing routine is. (Maybe this has to do with
X11 as well, but I think the sluggish redrawing happens on OSX too.)
This all is particularly problematic when combined with Pd's
architecture, because it's often sending a barrage of messages to the
gui. For example:
* an error message to the console. The console is fairly snappy when
dealing with an email's worth of text, not so snappy when dealing with
100 error messages being sent every 10ms.
* moving a large number of objects in Pd-extended or Vanilla
* moving an array in Pd-ext or Vanilla
* resizing an array where each element of the array is an svg tiger

Re: [PD] cosinesum vs sinesum in arrays
When sending the cosinesum message to an array, don't you have to specify the number of points too? And specifically a power of two? Plus, for a cosine you have to specify the first partial to have zero amplitude and the second an amplitude of 1 (or less). So the message should be something like [; array999 cosinesum 1024 0 1( First the name of the array, then the cosinesum function, table length and partial strengths. Hope I got your question right..

Re: [PD] get sinusoid from a sine and a cosine oscillator
What you seem to be doing is creating a spectrum which has magnitude 1 everywhere, and the phase is varying at a constant rate vs frequency. That means it has a constant group delay. So... my guess is that you'd get an impulse in each block, whose timing depends on the rate of the phasor. When you vary the phasor frequency, it will coincide with the peak of the hann window at some point and be its loudest. Should be a periodic complex tone. I don't understand your goal: you've got sinusoids in the patch... to generate sinusoids?

Re: [PD] get sinusoid from a sine and a cosine oscillator
Yeah, well I'm trying to create shapes in Gem (say a circle) and create the sound they make. So, to make a circle, I'm making a ramp from 0 to 1, multiply it by 2pi and send it to [cos] and [sin] and store these values in two tables, which I then read for every instance of a [circle] (using [repeat] and [separator]). So, since for any shape, you need two coordinates, x and y, my thought was to use these two coordinates as the real and imaginary part of an FFT, merging the two dimensions in one. After the sinusoid, I'll try to make other shapes too, but I wanted to start from that to make sure that I hear exactly what I see.

When I use something like x(-30:30)(-1:1), it jumps between -30 and 30. Then use the same field variable for your [drawnumber].

Is there a way to make the number catch the keyboard no matter where I click in the rectangle? To answer my own question: I had some thought about dealing with the 'capture the keyboard' part. When clicking the rectangle, I could use the pointer to route keyboards events from [keyname] to the clicked scalar. This way, I could even use 'Left' and 'Right' key events to move the scalar selection with the keyboard. This would allow to set a whole array of numbers by only using the keyboard. It's still not clear how to unselect the whole thing, when data entry is completed, though. I believe many interfaces allow de-select something by clicking anywhere nearby. Don't know if that is feasible in Pd. Using a key would be another option. The 'Escape' key, for instance.
