asio clarification
by David Sabine 25 May '02

25 May '02

Hello, Should PD use MME or WDM asio drivers? I've purchased a Roland UA-5 and according to their support documentation the MME and WDM drivers cannot be installed on the same machine at the same time -- I have to choose ONE or the OTHER. I'm using Windows XP. This is really the first question in a long list of questions I have about asio with PD: the others include: 1. why does PD 'hang' when I use the -asio flag. 2. why doesn't the -soundindev and -soundoutdev flags work? (I can't select any device other than the system default device.) 3. and I have a lot of questions for Roland too!

About dynamic patches
by Yves Degoyon 25 May '02

25 May '02

hi, i made a small and very limited patch that uses 32 filters to slice the sound by frequency ranges and then re-synthetize it with 32 oscillators. it sounds quite ok but i'd like to change dynamically the number of filters ( which is now hard-coded to 32 ). this would require a real maestria in dynamic patch creation that i'm not sure to have right now. also, this would be a good test for dynamic creation stability. so, i'd be pleased if someone would take the time to improve this little tool or give me hints. the main patch is "test-banks.pd" cheers, yves/

hi, did you consider using netsend/netreceive in your patches, i use them to cummunicate with Apache's CGIS and it's stable. for some other reason, one might want what you ask. for instance, if you want to open a connection to a database and keep a cache of fetched datas ( in php, perl or whatever, ... ) cheers, yves Bo.T wrote: >Hi all, > > since i seem to have the usual habit of asking questions that >no one else knows the answer to either, i thought i'D ask >an easy one. > > can the ggee shell external start a process (via a shell script) >that keeps going? > > I keep trying it and it does not want to work, the ps aux >command gives [pd <defunct>], which seems to correspond to >the nonrunning process that I am trying to run. > > for those interested, i am trying to get PD to start >a script that used pdsend and pdreceive objects to >act as an interface for the PD process to other programs. >I would like to be able to do this so I can have a little >local patch that I call up with unique port numbers as >arguments and they will be used for communication >between the main PD patch and the external programs.

web publishing suggestions
by John Saylor 24 May '02

24 May '02

Hi I'd like to put some of my music on the web. Right now, I can think of 2 options: 1. run my own webserver 2. use mp3.com Both have their problems. I *could* run my own webserver, but then I'd have to manage it [still OK], but it's on the attbi.com network. This means it's address changes whenever they decide to renumber the network. And if I bought my own domain I'd need to update DNS, and they might start charging me a lot if a lot of people want to download my music [hey- it *could* happen ...], and so on. mp3.com is pretty much as commercialized of a site as is out there- with required registration to download songs, cookie tracking, selling your email address to spammers, and probably lots of other stuff I don't even know about. Any suggestions, comments, or meandering diatribes on this subject are welcome. -- \js Q: How many existentialists does it take to screw in a lightbulb? A: Two. One to screw it in and one to observe how the lightbulb itself symbolizes a single incandescent beacon of subjective reality in a netherworld of endless absurdity reaching out toward a maudlin cosmos of nothingness.

shell and ongoing processes
by Bo.T 24 May '02

24 May '02

Hi all, since i seem to have the usual habit of asking questions that no one else knows the answer to either, i thought i'D ask an easy one. can the ggee shell external start a process (via a shell script) that keeps going? I keep trying it and it does not want to work, the ps aux command gives [pd <defunct>], which seems to correspond to the nonrunning process that I am trying to run. for those interested, i am trying to get PD to start a script that used pdsend and pdreceive objects to act as an interface for the PD process to other programs. I would like to be able to do this so I can have a little local patch that I call up with unique port numbers as arguments and they will be used for communication between the main PD patch and the external programs. Doing all this by hand is a pain in the bum. Hope someone can tell me, or tell me that it is not possible. I thought i had seen this on the list, but cannot find it anymore :-< chrz, tm -- -------- ------------------------------------ \ / Tim Boykett mailto:tim@timesup.org \ / TIME'S UP \/ Industriezeile 33 B /\ A-4020 Linz /xx\ ph/fax:+43/732-787804 /xxxx\ http://www.timesup.org -------- ------------------------------------

applying a delay filter to a tableread?
by Joao Rui 23 May '02

23 May '02

Greetings to all on the list. Normally I wouldn´t ask for something like this here because the list isn´t intended for these topics but I am desperate to get this to work for a school project. I am trying to apply a reverse factor on the playback of a table. I now how to do it with a phasor but not with a ramp (line~). I´m still a newbie on PD so can some explain to me how can I do this? I´ve included the patch I´m trying to do this on, I have a mic that picks up voices, thats what the table records. Does anyone know of tutorial for PD besides the docs that comes with it? Something with a tad more steps? many thanks Joao

I've 'sort of' answered my own earlier question. On the portaudio web site I found the following: Some advantages of using DirectSound are that DirectSound may have lower latency than WMME, and supports effects processing plugins. But one disadvantage is that DirectSound is not installed on all PCs, and is not well supported under Windows NT. So WMME is the best choice for most projects. DirectSound - If you want to use the DirectSound implementation of PortAudio then you must have a recent copy of the free DirectX SDK for Developers from Microsoft installed on your computer. _____________ According to that documentation (more at http://www.portaudio.com/docs/pa_tut_pc.html) Port Audio will work with both WDM and MME; however, the choice is really determined by my computer's configuration and whether or not I have DirectX installed. _____________ Has anybody had any success with PD using ASIO MME? Has anybody had any success with PD using ASIO WDM? Has anybody had any success with PD using ASIO? Regards Dave S

question about 09.pvoc.pd
by cb 22 May '02

22 May '02

Hi, I've been studying DSP theory, FFT-based techniques in particular. I've found the FFT tutorials in PureData to be a great place to see those techniques applied to sound. However, one little implementation detail still has me confused: In the engine of the phase vocoder patch (the FFT-ANALYSIS subpatch), there is a Float object which is used to calculate the next read location in milliseconds. This value is then converted to a sample position & passed through a Line~ to specify the start location of the first Tabread4~. What I don't understand is why the conversion of the Float from milliseconds to samples doesn't take into account the overlap of the subpatch-in other words, why isn't the local sample rate used, instead of the sample rate of the parent window? Thanks in advance for any insight anyone might have to share. Chris Campbell cb(a)inner-ear.net

extensions to expr object
by Orm Finnendahl 22 May '02

22 May '02

Hi, I extended the expr object so that it now includes the floor, ceil and fmod functions from ANSI C as well. The patch for vexpr_fun.c and a short demonstration of the new extensions is attached. Miller, would you be willing to incorporate that in a future release? That'd save the hassle of patching it for every upgrade on my machine :-) Yours, Orm
