high frequency control data
by Josh Whiting 07 Nov '01

07 Nov '01

hi all I am attempting to use a phasor~ linked to a threshold~ unit to generate high frequency bangs to then trigger a reasonably complex sample playback mechanism, attempting to mimic granular synthesis. The problem is that when i bring the phasor frequency up into the range of audible pitch, say above 100hz, i can hear a low frequency cyclical shift in the sound texture, which theoretically should be completely even. So, my question is this: how do non-signal objects function when your trying to use them at signal rates? I.e., what happens in a "threshold~ 0.9 0 0.1 0" object when your giving it a phasor signal that is perhaps 500hz, or in a "route" object with inputs coming at these frequencies? Is there a way to set the non-signal and signal object speeds to be equal? (in CSound, this is equivalent to setting KR to SR, and KSMP to 1). I have a hunch that what is happening is a kind of artefact of the slower speed of the non-signal objects, that somehow a bang or two is getting held over to another processing chunk or something... any input would be highly appreciated.. thanks! josh whiting, hampshire college jsw98(a)hampshire.edu

Fwd: Re: [PD] pd-lib.sourceforge.net?
by Rory Walsh 06 Nov '01

Well would it be possible to keep a simplified version of the list, something which could be published on this list perhaps? Even if it was just a list of the objects which have been created to date? I'm only interested because it will give developers a clear idea of what's been developed and what has not? --- Karl MacMillan <karlmac(a)monk.peabody.jhu.edu> wrote: > From: Karl MacMillan <karlmac(a)monk.peabody.jhu.edu> > To: Rory Walsh <rorytheroar(a)yahoo.com> > Subject: Re: [PD] pd-lib.sourceforge.net? > Date: Mon, 5 Nov 2001 08:15:19 -0500 > > This project is dead - if you or anyone else would > like to take over just let > me know. > > Karl > > On Sunday 04 November 2001 12:47 pm, Rory Walsh > wrote: > > Can anyone tell me if there are any plans to > update > > the pd-lib at sourceforge.net?

Re: [PD] compiling example extern
by Greg Rippin 06 Nov '01

06 Nov '01

Hi everyone, Making progress on this. . . I see in the m_pd.h file how the #ifdef looks to see if it's being compiled in C++, and if so wraps it in "extern C{}". I'm still having linking errors, trying to build the "foo1" example (a bunch of unresolved external symbols, all of which are defined in m_pd.h. This occurs even if I wrap the foo1.c code. My attention is drawn to a later #ifdef, which conditionally redefines the external storage class "extern" if you are using NT; would the fact that I am using Win98 and not NT keep this #ifdef from being executed properly? One last thing. . . In the pd documentation on externs, it says "To compile, type "make pd_linux", "nmake pd_nt", "make pd_irix5" or "make pd_irix6"." What is this referring to (in other words, where do I type "make pd_nt")? Thanks again for all the help.

pix_video pal
by Ulrich Kehrer 06 Nov '01

06 Nov '01

hi, yesterday i recompiled gem with guenter's pal-support for the pix_video object (http://iem.kug.ac.at/mailinglists/pd-list/2000-07/0028.html). it compiled fine but when i try to use pix_video now i always get /dev/video0: Device or resource busy. the old Gem.pd_linux' pix_video has no such problems (unless the missing pal support and thus being black and white). xawtv works perfect, too. anyone? cheers, ulrich

New GrIPD v0.0.8
by Joseph A. Sarlo 06 Nov '01

06 Nov '01

A new version of GrIPD is available at the usual place: http://mambo.peabody.jhu.edu/~jsarlo/gripd/ -Fixed the align horizontal and align vertical functions -Added joystick support (not sure if this is useful to anyone else, but I needed to control PD via a joystick over the net and use my GrIPD GUI, so there it is!) -- ______________________________ | | Joseph A.

does anybody know if there is something like a realtime motion or color tracking software (like bigeye) for pc which gives out midi signals? i would be really happy if some genius programmer could compile such an object for gem.

pd-lib.sourceforge.net?
by Rory Walsh 04 Nov '01

04 Nov '01

Can anyone tell me if there are any plans to update the pd-lib at sourceforge.net? The last time it was updated was May 2000? Or can anyone tell me of another list somewhere? There are plenty of objects on that list that have since been developed. regards, ROry. __________________________________________________ Do You Yahoo!?

iiwu for PD?
by Larry Troxler 04 Nov '01

04 Nov '01

I am (yes I admit it) looking for a way to play soundfont intruments within PD. I couldn't find any mention in the list archives, so I assume this there is as of yet not an extern to do this. It looks to me like it should be pretty easy to make a PD extern based on iiwu for this. There is already source code a jMax version of iiwu, and using that as a guide, it seems like it wouldn't be a major project to do the same for PD. In fact, I might do it myself, but first I want to make sure that there isn't already an iiwu extern for PD that I'm not aware, nor any other soundfont-player extern. Indidently, I notice that on the iiwu to-do list is a LAPSDA version, and I'm curious about how this could work, given the LAPSDA architecture of only accepting control inputs which presumbably are sampled at the host's audio scan rate. I guess what I am asking, is how you would make a LAPSDA midi-synth plugin - what would the intputs be? Control inputs for both midi key and velocity perhaps? Doesn't seem like that's in the spirit of what LAPSDA is intended to do? How would you trigger simultaneous note-on's for example? Oops, getting off topic here. Larry Troxler
