[PD] GEM window immediately closing
Hello list, I decided to take another crack at learning GEM today, and have immediately hit a snag. I'm using the 64-bit build of Pd-extended 0.43.4 from apt.puredata.info with the KXStudio distro (based on Ubuntu 12.04). Whenever I try to create a GEM window, it flashes for a fraction of a second and closes. With messages set to all, the Pd window says: GEM: Only using 8 color bits GEM: Direct Rendering enabled! GEM: GLEW version 1.5.4 GEM: Start rendering GEM: Stop rendering Any thoughts on why this is happening and how to fix it? .mmb ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] [biquad~] as max's phaseshift? (was [biquad~] as cyclone's [allpass~]?)
Yeah, my [filterplot.mmb] abstraction actually wraps the phase to -pi to pi and scales that to -1 to 1. I don't remember why I did the scaling. ;-) Also, I don't know if it matters with how you're analyzing [phaseshift~], but the frequency axis is non-linear. You can change it by sending a [linfreq 1( message (I think I forgot to put that in the helpfile). You're right that a second-order filter doesn't necessarily mean it is a biquad structure, but as long as it is a linear filter, you can recreate any second-order filter using a biquad. You just put in 0 for the coefficients you aren't using. However, second-order all-pass filters are likely going to be biquads, since the feedforward and feedback coefficients will be inverses of each other (i.e. b0 = a2, b1 = a1, b2 = a0). Anyway, I don't have access to Max these, so I can't really look at it. There is this filter described here ( https://ccrma.stanford.edu/~jos/pasp/Phasing_2nd_Order_Allpass_Filters.html) that gives a response similar to what you described with f = 4kHz and R = .1, but I don't think that's the one given what it says in the [phaseshift~] reference page. The paper describe this filter says R should be exp(-pi * bandwidth / samplerate), and that usually results in .5 R 1. Hope that helps at all. .mmb On Sat, Oct 5, 2013 at 7:14 PM, Alexandre Torres Porres por...@gmail.comwrote: hi mmb, thanks for showing up :) h, my problem was that the phase response graph generated from your Pd patch based on RBJ looks different than the one from max's phaseshift. But it just occurred to me that one thing about it might only be a matter of normalizing it and displaying in the same way. For example, your patch gives us a drop from 0 to -1 and then from 1 to 0, while phaseshift in Max is from 0 to -2pi continuously. I'm now considering that both behaviours could be related, only that your patch wraps it around -1 back to 1. What do you think? But even so, there's also the issue of getting the Q parameter to behave in the same way. Max's phaseshift, when set to Q = 0.1 and freq = 4KHz will give you a linear drop from 0 to -2pi. Now, I can't seem to get that based on RBJ's cookbook formulas and your patch. But then, another thing I haven't thought of might be a difference in the scale plot... One way or another, the Q parameter seems off. So, as you can see, there are these plotting differences, but I know what you mean, that is what I was suspecting too, it sure looks like the same thing at a first glance, meaning you can get to it from a biquad coefficient perspective. The problem is that max's phaseshift isn't very clear about what it really is, other than saying it is a second order filter. But that doesn't have to imply it is the same as a second order biquad, does it? Thanks 2013/10/5 Mike Moser-Booth mmoserbo...@gmail.com From looking at the helpfile for [phaseshift~], this sounds very much like the all-pass filter from Robert Bristow-Johnson's EQ Cookbook. You can calculate the biquad coefficients for it like this: w0 = 2*pi*frequency_in_Hz / sample_rate alpha = sin(w0)*sinh(ln(2)/2*Q*w0/sin(w0)) fb1 = 2*cos(w0) / (1+alpha) fb2 = (-1+alpha) / (1+alpha) ff1 = -fb2 ff2 = -fb1 ff3 = 1 .mmb On Sat, Oct 5, 2013 at 12:31 PM, Alexandre Torres Porres por...@gmail.com wrote: the phase response given in phaseshift's help file suggest otherwise. it's more like the response from miller's H14 example... So I guess you can have a 2nd order one (lie phaseshift) by putting two of these together, right?

Re: [PD] [biquad~] as cyclone's [allpass~]?
It's not that either implementation is wrong, they are just two ways of doing the same thing. The version that uses two delay lines is the Direct Form I. By doing some rearranging of the filter, you convert it to the Direct Form II, which only uses one delay line. The end results are the same, just one is more efficient.

It requires Pd-extended 0.43 to run. I just got to a beta state, it works
well for me, but it does crash Pd sometimes when you close a patch with
[filterview] in it. Try it out and let me know how it works for you.

Also, as a side note, this object is an experiment with a new way of
writing GUI objects. It started out as a pure Tcl program, and the GUI part
still runs as a standalone Tcl program (try running ./filterview.tcl from
the Terminal). This makes development and debugging vastly easier.
Additionally, I tried to move more of the GUI code to the Tcl side, so
you'll see that it uses fewer widgetbehaviors, and uses Tk's bind feature
quite a bit.

Right. But why is it looking for that one if the correct one is included in the Pd-0.43.1-extended app? When I took out the one had installed, I still got the error.

I think a and c should be switched here, though of course when finding b²-4ac that doesn't really matter. It depends whether you write ax²+bx+c or a+bx+cx². Both forms are convenient, and the latter expands better in cases of variable degrees (letters don't get renamed when adding a term), but the former is more common for cases that have only a degree fixed at 2 or 3. Ah, okay. Also, when applying a gain to a recursive filter, it's not really the same as scaling all the coefficients. If you were to scale them first, then the gain would affect the feedback portions of the filter. Applying the gain after means the feedback samples are not scaled by the gain. Those filters are all linear. This means that you can effectively commute them with a constant gain [*~] without any difference. However, it will make a difference when the gain of [*~] changes quickly while the main input changes too. Right. I was just saying that, if you separate the gain from the filter, the gain has to be applied at the input or the output. It's a single operation. So if you incorporate it into the filter, scaling the feedback coefficients has the effect of making it multiple operations. Or at least that's how I understand it, anyway. At any rate, the only reason I picked up on that in your previous email is because I wanted to plot the frequency response of [bp~], and at first I just applied the gain to all the coefficients without thinking about. It didn't work. Then I remembered the gain should just be applied to the FIR part of the filter, and it worked fine. If you think of it in terms of its transfer function, it would look more like this: H(z) = g*(1 / (1 - 2r*cos(ω)*(z^-1) + r^2 * z(^-2) )) Well, I was thinking of it in terms of 1/H(z) or 1/gH(z). But are you sure that you got the signs right in the denominator ? Pretty sure, though I mess that up all the time. Aren't you supposed change the signs of the feedback coefficients when z-transforming the difference equation? .mmb -- Mike Moser-Booth - mmoserbo...@gmail.com Master's Student in Music Technology Schulich School of Music, McGill University Centre for Interdisciplinary Research in Music Media and Technology If you think education is expensive, try ignorance -Derek Bok ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I think it has to do with where c is in the difference equation: c*y[n] = g*x[n] + a*y[n-1] + b*y[n-2] This equation uses a for the middle term (y[n-1]) ? Weird. I'd expect b to go with y[n-1], whereas a and c would go with either y[n] or y[n-2]... Sorry, I kind of confused myself. I'm used to thinking of the coefficients as a_0, a_1, etc. You're right, b should go with y[n-1], and the one that should go with y[n] is which ever one is equal to 1, which would be c if you think of it as a + bx + cx^2, not ax^2 + bx + c. To clarify, think of the z-transform of the filter as H(z) = 1/A(z), where A(z) = 1 - 2r*cos(ω)*z^-1 + r^2*z^-2. If we decide c=1, b=2r*cos(ω), and a=r^2, we have A(z) = c - bz^-1 + az^-2. In order to apply the quadratic formula, those exponents need to be positive, so you have to multiply by (z^2)/(z^2), which leaves you with H(z) = z^2 / (cz^2 - bz +a). That's what I meant earlier when I said a and c should be switched, and I thought you were trying to say that you were thinking in terms of a + bx +cx^2. ;-) BTW, the equations I used are things that I reconstituted from the source code of [biquad~] in pd/src/d_filter.c. They don't come from manuals. You mean for [bp~]? The equation used for [biquad~] is in the helpfile, if I'm not mistaken. But, yeah, that's what I'm going off of, too. btw, you wouldn't happen to know where the source for [vcf~] is, would you? I'd like to know how that one works as well, but I can't find it. .mmb ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Its now solidly beta, so we’re looking for testers. Download a nightly build to try here: http://autobuild.puredata.info/auto-build/latest/ First off, the pd-gui side of Pd has been re-written from scratch. When you run Pd, you are actually running two programs: pd is the core engine and pd-gui is the GUI. Since basically all computers now come with multiple CPU cores, this means that pd-gui will usually run on a separate CPU core than pd, so they don’t step on each other’s toes. pd can entirely take over its own core. If you want to make your patch use more CPU cores, then check out the [pd~] object introduced in the last release (0.42.5). pd still handles some of the GUI stuff, but we are working on splitting that out for the 0.44 release. That is a big chunk of work but it will also bring big gains. In particular, it means that it will be possible for people to write their own GUIs for Pd, covering not just the display of the patch, but also the editing, and everything else. You like OpenFrameworks, python, iOS, JUCE, Qt, etc.? Write your own pd-gui using the toolkit of your choice. That’s the idea at least. That will take a solid chunk of work, so we are looking for people to join that effort. There are so many ideas for making a better editing experience in Pd, this release makes big strides to address the editing experience. There are new features like Magic Glass, Autotips, Autopatch and Perf Mode, all available on the Edit menu. • Magic Glass let’s you magically see the messages as they pass through the cords. Just turn it on and hover above a cord, and you’ll see the messages as they go by. You can even look at signal/audio cords. • Autotips gives you tips about what an object does, what its inlet expects, and what comes out of the outlets. • Autopatch mode automatically connects objects as you create them. • Perf Mode, is a mode for performance that makes it harder to accidentally close windows that are part of your performance. The Pd Window is also majorly overhauled. First of all, its fast. Much much faster than the old one. You can now print thousands of messages per second to the Pd Window and still edit your patch. No more will an accidental dump of info cause the GUI to freeze up (well, ok, maybe if you send 10,000 messages/second but that is a way too many). There are also now 5 levels of printing messages to the Pd Window: fatal, error, normal, debug, all. If you are only interested in fatal errors, switch the Pd Window to 0 – fatal, and you’ll only see the worst problems. You want to see every single message to debug? Switch to 4 – all, and you’ll get the whole firehose. There is also the new log library, which lets you easily send messages for those different levels. And all messages logged with the objects from the log library are clickable: when you Ctrl-Click or Cmd-click (Mac OS X) on the line in the Pd Window, it’ll pop up the patch where the message came from, and highlight the specific object that printed it. That even works for many messages from other objects as well. The Pd Window also includes very basic level meters for monitoring the input and output

The input parameters f (centre freq) and s (sampling rate) and Q are transformed like this : ω = 2πf/s r = 1-ω/Q a = -r² b = 2r*cos(ω) c = 1 (an overall gain is applied separately, which is like scaling a,b,c all at once) I don't think this is entirely accurate.

This equates to simply scaling the input of the filter. It seems that [bp~] is a mere combination of a [lop~], a [hip~] and a [*~] (plus the calculation of their coefficients). But [hip~] isn't an all-pole filter.

No problem! balance.mmb~ is quite usefull, in it's help file I'd like to know why there is an amplitude modulation when changing cut-off frequency is this coming from level adjusting from balance.mmb~ or something else? Yes, I believe so. It's using [env~] to estimate the rms value, and when changing the cutoff the rms level isn't constant across the analysis frame. Also, [env~] gives the previous frame as a message, which is then converted back to an audio signal. So there's some delay in the adjustment. I could try and make one that doesn't use [env~] and stays in the audio domain and see if that helps. In other help patches there are several objects missing, I guess they have been done with pd-extended, but not all libraries are enabled by default in pdx, so it's not easy to find out which one to use for having all your patches working. Hmm, I'm using the default startup libraries for Pd-extended 0.42.5 on OSX. But it didn't occur to me that people may have disabled them. I think the only non-default library I used is iem_tab, and I believe they're [import]ed. Beyond that, mostly cyclone and zexy. Why file browser likely won't work on windows? IIRC, because it internally formats the paths without considering that they could start with C: or whatever. It might work, I just haven't tested it. where count~ come from? cyclone why not make all your patches vanilla compatible? It's not practical for all of them. Some of them require mouse interaction, some require calculating long tables which [until] is too slow for (hence iem_tab), and others just do things that I don't know how to do in vanilla. ;-) There are likely a few things here and there that could be vanilla and aren't, but in general I stick with vanilla if it's practical to do so. in biquad.mmb~-help.pd it uses filtercoef.mmb~ instead of filtercoef.mmb, so there are errors in console because a bang is coming into inlet~ Ah, thanks.

I'll happily help you get that going if you are willing to take it on. I don't think it would be very hard to do. Basically, just take the plugin I wrote, but bind to the canvas widget that the object makes rather than the patch window. Then it would call a Tcl proc which would send the info to pd to be output from the outlet. hcs/cursor is an example of that. What I've been thinking of doing is have file association patches, so like wav.pd, mov.pd, mp3,pd, etc. Then when you drop a .wav file onto a canvas, it would copy-n-paste the contents of wav.pd where you dropped the .wav file. .hc On Sep 19, 2011, at 12:53 PM, Mike Moser-Booth wrote: A bit of a variation on what João is suggesting, but I think a simple [cnv]-like gui object that will take a drag-and-drop file and output the path and filename would be nice.

Hey Christian, I'm not too sure what the advantages of using [coords( over [donecanvasdialog( other than avoiding the dirty flag, but I stopped using [coords( a while ago for similar reasons (I found that it inconsistently tended to leave an outline around GOPs that were moved). What I usually do for modifying GOPs on the fly is to use a [donecanvasdialog( message to turn GOP off, make the necessary adjustments, then use a second [doncanvasdialog( to turn GOP back on. I find this particularly takes care of a lot of modifying GOPs within a GOP issues (I'm not clear if that's the case for you). You also have to follow it with a [dirty 0( message to avoid do you want to save? dialogs. I can't say for certain that it works in all situations, but I haven't had any problems with this approach yet. .mmb On Tue, Jun 28, 2011 at 10:51 PM, Christian Haines christian.hai...@adelaide.edu.au wrote: Hi All I have created an GOP abstraction which I include in a parent parent. The GOP interface has a button that resizes it by sending a 'coords' message to the GOP abstraction canvas (namecanvas named). When it resizes larger it renders the larger interface properly over the patch's white background. However, when it resizes smaller it leaves a remnant of the larger interface visible. Sometimes to correctly show the smaller interface, I have to redraw / refresh the window by moving the window - this doesn't always work though. In fact it only works when the parent patch has a '#coords' line with a specific configuration in it - of which I'm not sure. I'm on OSX. I've seen the issue documented elsewhere but never read a full description on how to resolve it fully. See the issue here: http://echoblue.com.au/pd/goprenderissue.mov At the moment I am sending a message back to the parent patch from the GOP abstraction to change the parent patch's 'setbounds' by 1 pixel and then move it back - this resolves that issue but, as mentioned, not consistently. Regardless, it creates two more issues: (1) setbounds behaves oddly - doesn't resize until a close and reopen; and/or moves the objects in the patch window without resizing; (2) I can't know the patch window size dynamically (say by querying the canvas) hence any size change by setbounds is not necessarily the same as the original window size (if it was resizing!).

I think people should realize it, but the helpfile will probably remind them, too. I mean, I'm the type of person that would probably want to see it, but I don't think it's something that always needs to be seen. In general, I don't think people are particularly interested in how a lowpass filter affects the phase, and if all you're looking to do is lowpass filter a sound, it probably won't matter. Besides, the units don't line up. The y-axis goes from 25 to -25 dB in the magnitude response pi to -pi radians in the phase response. That's something that could confuse someone who doesn't really understand phase alterations to begin with. I think it makes more sense to either be able to turn it on and off or switch between the two.

Re: [PD] algorithms for drawing filter response curves
I don't really know how to test this and I don't really know tcl, but I tried looking at the code to see if I could make some sense of it anyway, because why the hell not. ;-) Anyway, the only part I really understood was the calculation of the coefficients, and I noticed something wrong. You are calculating alpha for bandwidth instead of Q. I'm guessing you're just borrowing what is in the ggee externals (given the code's comments), because it's done the same way there, but it's not really conventional for a lowpass filter. That's really more for bandpass, notch, and peaking filters. Using Q is also a simpler calculation: alpha = sin(omega)/(2*Q). With Q set to .7071 (or -3 dBfs), you have a filter with no resonance, which makes sense because the cutoff frequency for a lowpass filter is defined as the frequency where the response falls be 3 dB. This is also how Max's [filtergraph~] works. It's all defined here in Robert Bristow-Johnson's Cookbook: http://www.musicdsp.org/files/Audio-EQ-Cookbook.txt The ggee externals, as far as I can tell, are all based on this cookbook, though with mistakes like using BW instead of Q.

Re: [PD] how can I clear [vd~]
Oh, I agree. I'd much rather use [vd~] than hack a workaround. But I don't think all of us are in the level of compiling our own externals (I, for one, have never done it). I'm merely suggesting it as an alternative. It is a pretty simple workaround, though. If you use [poke~] to write, then the delay time is just an offset to the index of [poke~].

Re: [PD] interface/pd-based standalone applications question
I've always thought that what Max considers standalones is kind of shady. They're just the patch and Max Runtime bundled together. The only difference is that the patch(es) used are put together in a single file (which Max calls a collective, but anyone with Max can open on their own and edit) and that the Runtime automatically loads the patch. It more just gives the "impression" of a standalone executable.

Re: [PD] MIDI In-to-Out Latency
Jim Aikin wrote: When I look in Pd's audio settings box, I find something rather disturbing. It doesn't give me access to the ASIO driver. So the latency with internally generated audio will _inevitably_ be 100ms or more. But: That should not affect the MIDI through routing when no audio is being generated! If it does, Pd is in serious need of optimization. It doesn't take 100ms to route three bytes through a buffer. Or at least, it shouldn't. There should be an item in the Media menu that says ASIO (via portaudio) that should be checked in order to use the ASIO drivers. For what it's worth, I've had the same problem in OSX routing MIDI through the IAC bus into various DAWs (haven't actually tried it yet on Windows XP). It's pretty frustrating.

Re: [PD] table abstractions
Hey Matt, I've been on vacation the past few days, so sorry for the late reply. But I just wanted to say that I very much like the idea of table-abstractions in the vein of Csound's GEN routines. I don't think I could be in charge of such a project either, but I would be happy to contribute wherever I can. .mmb Matt Barber wrote: Hello list, For a while there had been talk about starting a vanilla-only table-abstraction collection in the spirit of list-abs and the iem_tab objects. This could be useful both for manipulation of or calculations using table data and for populating tables with desired data (in the manner of the csound GEN routines). I'd love to start it, but I don't know if I have enough Pd cred yet to be in charge of it. There are a few problems I'd like input on: 1) Naming -- would it be worth it to have different prefixes for objects which manipulated data, e.g. [table-reverse], and objects which populated tables, e.g. [tabwrite-blackman]? 2) Input-Output -- for the ones which manipulate data, should that generally happen in place unless a destination table is provided -- [table-qsort foo] sorts table values in table named foo and writes results back to foo, while [table-qsort foo bar] would sort foo's values and write them into bar? 3) In general I'm assuming that the objects which populate tables should simply write to a table, not internally provide the table to be written to. For instance, I'm thinking a [tabwrite-hann foo] which writes a hann window into foo would be more useful than a [table-hann foo] which internally instantiated a table called foo AND wrote a hann window to it, and responded to messages like resize with a larger or smaller hann window (I think accessing the table from without might be too buggy for this to be worth it). 4) Interpolation -- I'm also assuming that anything which would write a table that would usually be read by [tabread4~] or [tabosc4~] should write the guard points for proper interpolation by default. I've attached an example [tabwrite-chebyshev], which writes a weighted sum of chebyshev polynomials of the first kind to a table, probably for use with waveshaping, as an example of what I'm thinking of, and of a few options members of such a collection might have. (Incidentally, it might be a good idea to abbreviate this particular one to cheb or cheby due to the many transliterations, or even something like chebsum to name it like the sinesum or cosinesum array methods.) My thought is that many of us have already been making and using abstractions like these, and I think it would be worth it to collect them in a vanilla library for general use.

Re: [PD] Max Smoother Audio than Pd?

Re: [PD] recording to array in loop mode?
If I'm not mistaken, I believe the trick to getting this to work is to make sure the array size is a multiple of the block size.

That's probably where the clicks are coming from. .mmb volker böhm wrote: thanks for your suggestions, guys. sorry, if i wasn't clear, but i'm not looking for (cross)fades. i'd like to perform circular recording into an array, constantly overwriting what has been recorded before. so if you put the playhead a little behind (or before - as it's circular it depends on your view) you get a simple delay. as the trigger to start recording with tabwrite~ is not sample accurate, i can't get a constant recording without clicks at the trigger points - at least not with my limited understanding of pd. but i think i've just found a solution using poke~ (which seems to be the same as in max). thanks, volker.

Re: [PD] pow~, etc. in Pd-extended 0.42.5
While I like the idea of backward compatibility, I would prefer more cross compatibility. If Pd-extended continues to default to cyclone's [pow~], there will still be issues with compatibility between different versions of Pd in the future and the [pow~] problem will persist. While old patches may experience problems, future patches won't. Better to take care of it now than later. I don't know how annoying it would be, as I don't use it that often anyway (I usually stick something like that in [expr~]) but what if a little warning message showed up in the Pd window when a patch loads with [pow~], at least in the next release or two?

Re: [PD] clap clap bonk bonk
Pop filters are just meant to catch bursts of air, not sound. Plosive vocal sounds, like "p" and "t", tend to send bursts of air into the mic, which cause the same type of distortion you get in windy conditions. Pop filters block this while having almost no effect on the sound, so one does not have to angle their voice off the mic, which, of course, makes a significant difference in the sound. .mmb Justin Glenn Smith wrote: Mathieu Bouchard wrote: On Mon, 12 Oct 2009, Miller Puckette wrote: I've tried clapping into mics and cant get consistent results -- the burst of air goes in all different directions and I could never get a consistent sound into the mic at all. ... i just looked up "pop filter" when seeing that word in cgc's reply, and it seems like it's a highpass filter, though it doesn't use those words in the description I read, but I guess it from what they say about clipping and aspirated plosives. http://en.wikipedia.org/wiki/Pop_filter but this article is weird, because it mentions the hiss but doesn't say what a pop filter does about hiss... It is not so much a question of highpass vs. lowpass as it is a directional filtering - the pop filter attenuates the most direct path of the sound, and if I am not mistaken they are designed to attenuate more with a higher energy burst of sound (this attenuation achieved via air turbulence), in order to filter more strongly on the loudest sibilants (high pitched) and plosives (low pitched) while affecting the quieter sounds as little as possible.

Re: [PD] making scales from frequency values
How do these objects even out your ratios (or, I guess, what do you mean by that)? Finding the difference between two frequencies after converting them to a MIDI value allows you to work linearly instead of logarithmically, which is just easier--well, for me anyway. For example, after converting 912Hz and 1081Hz to MIDI and getting the difference, you come up with 2.9431. Now you can just think of them as 2.9431 half-steps apart, and that one number will work starting from any pitch. If you stick to the frequency realm, you'll have to consider them a ratio of 912:1081, which is fine, but a little ugly and not as easy. As far as filling in the gaps, I don't know if this will help at all or not, but it might be something to think about. When you look at how the major scale is constructed, it can be seen as taking advantage of the first few harmonics in the harmonic series. I'll use the C major scale to (try to) illustrate. Going up from C in the harmonic series, you get an octave, a fifth (G), another octave, a major third (E), and another fifth [1]. Those last three notes are a C major triad (C-E-G). Now, stepping back a bit, the first note other than C in the series is G, the fifth, or dominant, in the scale. If you go the other way, down a fifth, you get F, the subdominant. Now, taking the intervals from the C major chord and applying them to G and F, you get G-B-D and F-A-C, respectively. The notes in those chords are what is used to fill in the gaps, and now you have all of the notes of a C major scale: C-D-E-F-G-A-B. I mention all of that because you're already working with partials. So perhaps working with an interval or ratio between two of your partials and applying that to another of your partials to generate new frequencies might get you somewhere. Or it might suck, who the fuck knows :-). Either way, this sounds like an interesting project, and I'd be interested in seeing where you go with all of this.

Also, they use a an abstraction variant of [biquad~] called [e_beequad] that allows for signal control instead of message. The equations used are also nicely documented within the patches. http://trac.rjdj.me/browser/trunk/rjlib/rj .mmb On Sun, May 17, 2009 at 9:03 AM, brandon zeeb zeeb.bran...@gmail.comwrote: Derek, Thanks for the complete list! This is very helpful. I was hoping to start off by using Vanilla-only objects. Does anyone have some good examples of how [biquad~] can be used to replicate standard low/high/band pass filters w/ q?

[lop~], [hip~], and [bp~] are nice, and can easily be strung serially to create 2nd, 3rd, and 4th order filters, but lack q. [biquad~] seems up to the task, but I'm unable to find any information in the help file or docs online pertaining to how one could replicate standard filters using this object. -- ::: derek holzer ::: http://blog.myspace.com/macumbista ::: http://www.vimeo.com/macumbista ::: ---Oblique Strategy # 164: Twist the spine ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- Mike Moser-Booth mmoserbo...@gmail.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] message routing question
Hello, The outlets of all objects in Pd output from right to left order. Also, the leftmost inlet is the hot inlet, meaning it will cause the object to output when it receives a value. So with your current setup, they rightmost outlet of [unpack] is triggering the leftmost inlet of [pack] before it receives the rest of the values from [unpack]. You could instead rearrange the list with a message box like this: [route notein] | [$3 $1 $2( | [route 4 1 2 3] The display showing the last value first is just the [pack] outputting the last numbers it received from the previous time you ran the sequence. .mmb Chuck Wiggins wrote: I'm fairly new to PD, and have a behavior in a patch that I can't understand - perhaps someone can enlighten me. I've reduced the problem down to a simpler patch layout - see attached file. My goal is to read midiin messages from a file via a qlist object, and route them based on channel. I matched up unpack and pack objects to transpose the midiin arguments so I could subsequently route based on channel. But I think a bang event is firing on the pack before it has all the arguments - the first print statement is not the first message from my file. I tried even introducing a 1ms delay before sending the leftmost argument to pack, but that soon got out of sync. Also tried a few approaches storing in floats. Any suggestions? I'm sure it's a basic PD behavior that I just don't quite grasp yet. Running the attached patch will show the sequence below. The print statement from the [route 4 1 2 3] object is displaying before the one from the [route notein], and the first value it shows - "42 0" - is not the first midiin message from my file - in fact it's the last.. print: 42 0 print: notein 50 127 4 print: 50 127 print: notein 50 0 4 print: 50 0 print: notein 45 127 4 print: 45 127 print: notein 45 0 4 print: 45 0 print: notein 47 127 4 print: 47 127 print: notein 47 0 4 print: 47 0 print: notein 42 127 4 print: 42 127 print: notein 42 0 4 Thanks much, Chuck ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] strange wave
Hans Roels wrote: Hello, Sometimes when I record audio in Pd, a wave file is created that Pd can't open or play. If I try to open this wave file in an other audio program like Audacity, this is also impossible. VLC player does play the file though and when I open this file in Samplitude a message "file does not contain sample data" appears but I can open the file. If I resave it in Samplitude it can be opened in Pd. I guess something is wrong in the headers of the wave file that Pd creates. In attach is a short example of such a 'strange' wave file. I hope that somebody can see what is wrong in this file... There is still something very 'shaky' in the 'writesf~ ' object in Pd, I guess about 25% of the times I try to record something, I have this kind of problem. An other problem that sometimes occurs is that only a file with a name is created but without actual sampledata (and this isn't caused because I don't leave any time between the 'open' and 'start' command for 'writesf'). I haven't succeeded in isolating the exact problem yet but I'm trying... (I think it has something to do with using 'writesf' in an abstraction). I 'm working on Windows XP and this problem occured in Pd 0.40.3 and in 0.42-4.

[PD] libraries not loading in Pd-extended .40.3

This is the first time I've upgraded, so I'm not entirely sure I did it the right way (I know some apps install things in weird places that screw up upgrades, and I'm a bit of a computer dumbshit in that regard). I just dragged the old .39 .app to the trash and installed this one. Is anyone else getting this?
