xcode compiling issue
by Andrew May 25 Apr '10

25 Apr '10

I'm having trouble using xcode to compile an external (not audio, pretty simple c code). Using Intel machine, OS 10.5, xcode 3.0; I followed the directions in : http://puredata.info/docs/developer/PdExternalsInXcode/ and it appears to compile cleanly. However, when I try to use the external in a patch I get a dlopen error: no suitable image found. Did find: ( ... the compiled external ... ): unknown file type, first eight bytes: 0x21 0x3C 0x61 0x72 0x63 0x68 0x3E 0x0A Has anyone found this error and/or a solution? Failing that, could anyone share a robust makefile for building an external that runs on both ppc and i386 using gcc? I tried that, but got "Undefined symbols" errors for all the pd classes (perhaps it's not finding m_pd.h, but I thought I set the path carefully enough...) Many thanks for any help!

Re: [PD] nusmuk_audio WAS: Max Smoother Audio than Pd?

anyway, whatever I'd say after this, the answer would be that I'm not a good musician, or that pd is not made for me, or even worth, that I don't have a good taste in music, etc... I think this is silly to enter into this, because I just want to contribute with my 'small' inputs, in spite of my small vocabulary. My conclusion is that pd isn't ready yet to put it at a very important place in composition, like a workstation, period. Also, many thanks for showing me the work of Richard Barret! ----- Mail Original ----- De: "João Pais" <jmmmpais(a)googlemail.com> Cc: "pd-list" <pd-list(a)iem.at> Envoyé: Mercredi 21 Avril 2010 14h28:31 GMT +01:00 Amsterdam / Berlin / Berne / Rome / Stockholm / Vienne Objet: Re: [PD] nusmuk_audio WAS: Max Smoother Audio than Pd? >> So maybe you need and want a shitty clarinet to achieve the objective >> you have, maybe you need a quite expensive one.

Conclusion: don't blame the clarinets, stop giving them wrong pieces. Don't assume that one clarinet is worthless because he's being given the right material to play with. _______________________________________________ Pd-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

very nice work! are you planning to add an enveloppe gen for controlling filter poles assignment or adsr ?

Re: [PD] nusmuk-audio / mixer aesthetics..

25 Apr '10

Hi I haven´t invented anything but I want to share this: http://servandobarreiro.es/wp-content/uploads/2010/04/mix_ser.png (just th image) It´s quite simple, but I find it useful for live performing situations.. (and Iike that kind of aesthetic..) maybe somebody wants to improve it.. I was thinking about adding a vu-meter per channel but at the moment, I manage ok with just two into the master section (still in progress..). In this case, the dac~ object it´s inside the mixer. http://minitronics.net/wp-content/uploads/2010/04/trondheim-minimixerpd.zip enjoy.. hello Roman I've tried Mx everytime I used netpd, so could tell what doesn't meet my criteria... there are already plenty of stuff for fx, that's nice, I've even stolen some stuff inside, like the dynamic routing, some times ago. In fact it's a pain in the **s do a good job in such a mixer because of aesthetics, anecdotic criterium in this conversation. There is no vu-meter in tracks, so we don't know where the signals come from, neither at each level it comes. There is no peak value detection, we don't know what was the last highest peak value, to find out what sound would overhelm the mixing equilibrium. Using different colors for the different bus is a very good idea, and make gaining time for finding the good slider, but some colors gives Mx an ugly apparence that could be avoided with choosing harmonious tones, for example a yellow handle over a white background slider, is just a pain for the eyes. Also the green color is very agressive. Mixing sounds is a kind of computation where the engineer need know accurately which level he has to give to some tracks for getting a correct average power, for example if we add 3 Decibels we double power... The necessary stuff is just a number box that would tell how much Db is modulated over a slider. here is my favorite mixing tool: http://www.soundonsound.com/sos/jan07/images/cubase5_l.jpg _ we can choose DAC~ input and output bus _ phase inversion _ Gain level _ Panning is over the number of output buses we choose _ A 'Listen' button has been added with 'Solo', but I didn't use it yet. _ we can record/play automation from the board. _ we can choose if the signal that goes to the bus is pre or post fader. _ same for vu-meter (all) _ we can record stuff passing through the mixer, if it's audio it records audio, if it's midi it records midi _ we can access directly to the instrument from the mixer track. _ there is an internal EQ, very usefull and very well implemented into to mixer track. _ we can group tracks into group tracks. _ we can save settings of each parts of the mixer. there are also all the settings that has effect on all the the tracks, like hiding all different parts of the tracks or setting peak detection time, copy-paste track params, an track edit window (so we can see all settings) ... For going further in the discussion, I'd need to try Mx EQ's and dynamic processing fx. This mixer is a cool project, and I'd love to use it in mine, but I'd need to make a stand alone patch. is there such one? ----- Mail Original ----- De: "Roman Haefeli" <reduzierer(a)yahoo.de> À: "colet patrice" <colet.patrice(a)free.fr> Cc: "João Pais" <jmmmpais(a)googlemail.com>, "pd-list" <pd-list(a)iem.at> Envoyé: Jeudi 22 Avril 2010 19h27:10 GMT +01:00 Amsterdam / Berlin / Berne / Rome / Stockholm / Vienne Objet: Re: [PD] nusmuk_audio WAS: Max Smoother Audio than Pd?

nbx: wrong return-behaviour?
by João Pais 25 Apr '10

25 Apr '10

Hi, I always noticed this behaviour, but never rememberd to say something about it. When a number is written in [nbx], it's necessary to press return - just like in a number box. But, unlike in a number box, after typing one value, if I want to type a 2nd value, when I press enter the number goes to 0. The only way to put in a new value is to click in the box again. Isn't this behaviour a bit contradictory? Not just because one number box behaves differently from the other, but also because it makes it much more laborious to input values one after the other. About the normal atom number box, one question: wouldn't it be better to allow it to have patch cords also when it has send/receive variables? (I guess that this has been discussed before).

I wonder, how to get rid of this ... I don't do very much looping, but if intuition serves I think you need to find loop points that share both the same value and the same first derivative (if your source is more or less periodic you can think of this as looping several sine waves and then mixing the results, and though I haven't thought it through it seems like the value and derivative would match best in places where the phase is similar for each constituent at the loop points). When I've tried to do looping, I've found it a little easier to find peaks with similar values, because I know that the derivative is the same at those peaks, while it's much harder to estimate the rate of change on zero-crossings. Anyway, for the sample you posted the best loop-point I could find was 2931-6153. Matt

connect arduino COM port
by Camilo Cadavid Corredor 25 Apr '10

25 Apr '10

Hello, I just got started working with arduino. Reading about the conection between Pd and arduino i found that i have to sync the firmware into the arduino board. After I do this i have to find out which COM port my USB conection gave the board. I have a MAC-OS X 10.6.3 version. Could someone please help me to find this... I appreciate it. _________________________________________________________________ Connect to the next generation of MSN Messenger http://imagine-msn.com/messenger/launch80/default.aspx?locale=en-us&source=…

VJ tools using pure data on Mac
by Adityo Pratomo 25 Apr '10

25 Apr '10

Hi all, I've been looking for a nice VJ tool on Mac. Been trying the resolume, but sadly my graphic card couldn't handle it. So, I've seen the pdvjtools and qeve patches made from Pd, but sadly this is for Linux only. So, is there any patch that I can use to do some VJ practice? Thanks and Regards, Didit
