Alex, > When you say: >> when I use the Built-in Audio I can send audio out but I cannot send >> it in > Did it work before and does not anymore ? Yes, the earlier version allowed me to use audio in and out when audio was set to Built-in audio. I could also send audio in and out with the Mbox but with only one channel. Now, I can get audio out to either the Built-in audio or to the Mbox but I cannot get audio in with either. Here is what I get when I type "pd -listdev" and the Mbox is not hooked up to the USB port % ./pd -listdev Digidesign CoreAudio Driver: DirectIO in use by another process. Our best guess at the PID is: 1788 Number of devices = 2 ---------------------------------------------- #1 DefaultInput Name = Built-in audio controller Max Inputs = 2, Max Outputs = 0 Sample Rate Range = 8000.000000 to 96000.000000 Native Sample Formats = paFloat32, ---------------------------------------------- #2 DefaultOutput Name = Built-in audio controller Max Inputs = 0, Max Outputs = 2 Sample Rate Range = 8000.000000 to 96000.000000 Native Sample Formats = paFloat32, ---------------------------------------------- could not open midi input device number 1: Invalid device ID. could not open midi output device number 1: Invalid device ID. using default input device number: 0 using default output device number: 1 nchan 2, flags 3, bufs 8, framesperbuf 256 Here is what I get when the Mbox is hooked up to the USB port % ./pd -listdev Digidesign CoreAudio Driver: Succesfully acquired DirectIO, our PID is: 1699 Number of devices = 4 ---------------------------------------------- #1 DefaultInput Name = Built-in audio controller Max Inputs = 2, Max Outputs = 0 Sample Rate Range = 8000.000000 to 96000.000000 Native Sample Formats = paFloat32, ---------------------------------------------- #2 Name = Digidesign HW ( MBox ) Max Inputs = 2, Max Outputs = 0 Sample Rate Range = 8000.000000 to 96000.000000 Native Sample Formats = paFloat32, ---------------------------------------------- #3 DefaultOutput Name = Built-in audio controller Max Inputs = 0, Max Outputs = 2 Sample Rate Range = 8000.000000 to 96000.000000 Native Sample Formats = paFloat32, ---------------------------------------------- #4 Name = Digidesign HW ( MBox ) Max Inputs = 0, Max Outputs = 2 Sample Rate Range = 8000.000000 to 96000.000000 Native Sample Formats = paFloat32, ---------------------------------------------- could not open midi input device number 1: Invalid device ID. could not open midi output device number 1: Invalid device ID. using default input device number: 0 using default output device number: 2 nchan 2, flags 3, bufs 8, framesperbuf 256 Pretty strange. I still have the other version of pd compiled in a separate directory. If I type "./pd -listdev" in that earlier bin/ directory, I get this: % ./pd -listdev Digidesign CoreAudio Driver: Succesfully acquired DirectIO, our PID is: 1705 Number of devices = 4 ---------------------------------------------- #1 DefaultInput Name = Built-in audio controller Max Inputs = 2, Max Outputs = 0 Sample Rates = 44100.00, Native Sample Formats = paFloat32, ---------------------------------------------- #2 Name = Digidesign HW ( MBox ) Max Inputs = 1, Max Outputs = 0 Sample Rates = 44100.00, 48000.00, Native Sample Formats = paFloat32, ---------------------------------------------- #3 DefaultOutput Name = Built-in audio controller Max Inputs = 0, Max Outputs = 2 Sample Rates = 44100.00, Native Sample Formats = paFloat32, ---------------------------------------------- #4 Name = Digidesign HW ( MBox ) Max Inputs = 0, Max Outputs = 1 Sample Rates = 44100.00, 48000.00, Native Sample Formats = paFloat32, ---------------------------------------------- could not open midi input device number 1: Invalid device ID. could not open midi output device number 1: Invalid device ID. using default input device number: 0 using default output device number: 2 nchan 2, flags 3, bufs 8, framesperbuf 256 PortAudio on OS X - Latency = 2048 frames, 46 msec Very strange, indeed.

You could make a related object [readsfmarker filename.wav] with 3 outlets: positions in msec and name and errors then handle -numeric messages as request for the position and name of the n-th marker -other messages as requests for the position of the markee with that name. pattern matching would be useful. Bang on the third outlet for n out of range or no match. There are several variants of course. Regards, Maurizio Umberto Puxeddu.

Alex, Ok, I tried this one and had mixed results. I show the Mbox with 2 ins and 2 outs but I am only able to send audio out no in through the Mbox. Also, when I use the Built-in Audio I can send audio out but I cannot send it in (through the internal mic). Weird huh?

Alex, I went back and re-read the entire thread. It explained it all. I have followed your instructions except the last items. I opened terminal and tried to "cd" over to the new "/pd/usr/" directory. I receive the response: No such file or directory. Did you mean pd/src/? There is a "configure" in there. I assumed that you meant pd/src/ so, I ran the ./configure and make from pd/src/. I still must supply command line flags to get it to work with my Fastlane 2X2 (USB MIDI). So, I typed the following at the command line: % ./pd -midiindev 0,1 -midioutdev 2,3 using default input device number: 0 using default output device number: 2 nchan 2, flags 3, bufs 8, framesperbuf 256 PortAudio on OS X - Latency = 2048 frames, 46 msec I can now send and receive MIDI from either port of my Fastlane. MIDI channels 1-16 come from portA and MIDI channels 17-33 come from portB. Just like it should. On the audio front. If I use the Built-in Audio controller, everything is fine. If, however, I try to use my Mbox things do not go well. It appears to only have 1 in and 1 out ./pd -listdev Number of devices = 4 ---------------------------------------------- #1 DefaultInput Name = Built-in audio controller Max Inputs = 2, Max Outputs = 0 Sample Rates = 44100.00, Native Sample Formats = paFloat32, ---------------------------------------------- #2 Name = Digidesign HW ( MBox ) Max Inputs = 1, Max Outputs = 0 Sample Rates = 44100.00, 48000.00, Native Sample Formats = paFloat32, ---------------------------------------------- #3 DefaultOutput Name = Built-in audio controller Max Inputs = 0, Max Outputs = 2 Sample Rates = 44100.00, Native Sample Formats = paFloat32, ---------------------------------------------- #4 Name = Digidesign HW ( MBox ) Max Inputs = 0, Max Outputs = 1 Sample Rates = 44100.00, 48000.00, Native Sample Formats = paFloat32, ---------------------------------------------- When I try to tell pd that it has 2 channels, like this: % ./pd -inchannels 2 -outchannels 2 -audioindev 2 -audiooutdev 4 -nomidi nchan 2, flags 3, bufs 8, framesperbuf 256 PortAudio on OS X - Latency = 2048 frames, 46 msec Error number -9999 occured opening portaudio stream Error message: Invalid number of channels. I am unsure of the meaning of the error message Error number -9999 If I lie to pd and tell it that the Mbox has only one channel: % ./pd -inchannels 1 -outchannels 1 -audioindev 2 -audiooutdev 4 -nomidi nchan 1, flags 3, bufs 8, framesperbuf 256 PortAudio on OS X - Latency = 2048 frames, 46 msec I can send and receive audio on one channel in and out. I wonder if this is a problem with the Mbox's coreaudio driver. Thanks again Alex, I really appreciate your helping me with this.

Re: [PD] Gem composite

If you have an accelerated graphics card I found the best way to mix video is with two objects. One video on one square, the other video on the other, then change the alpha value of the square in front to mix. Works very well, very smooth. you can also use ortho to remove the perspective. good luck.

I hope you didn't interpret my email as saying that you shouldn't release your objects. I was just listing off similar objects. The only thing I ask is that you try to avoid name clashes with existing Pd objects and Max/MSP objects. The GEM vs. maxlib scale for example, or different [counter] objs are a major pain. > > There is quantize~ in zexy. > > After looking at the source for this, it looks like this will quantize a > signal to a particular bit level, while mine quantizes to an arbitrary > 'grid' (quantization points are multiples of this value).

My two bits on this: in the interest of naming coherence, I think that same-named objects for audio- and control-rate, [quantize~] and [quantize] for example, should be as similar as possible. > I have used the database in the past, but it does seem to have some > serious holes there (as presented by me search of 'accum').

(I > do appreciate the easy C API that PD presents). This is happening somewhat with the SourceForge project. Basically, any external that doesn't have any lib dependencies is added to the pd-externals pacakge. There there are pd-osc, pd-flext, pd-zexy, and maybe some other packages. I think the way to solve the problem of tracking the new objects down is to have help patches that list all related objects on the page as well. Also, a hierarchical navigatible structure would be great. The VASP help patches are a great example. > It seems to me that most people who are working with PD are not really > interested in making a "prepackaged" program for others, but more a tool > that they can use for their own purposes. As for Pd users mostly being programmers, that may be true, but I a one of the people working on making Pd accessible to the non-programmer masses. I think the whole Pd community has a lot to gain from expanding the user base. .hc zen \ \ \[D[D[D[D

Hi, If you take that thread from the top everything has been explained. Here again, the installer from adam is good but a newly updated version of portaudio has been released that solves problems similar to yours. So you need to re-compile pd, for that get an 'extended2' tree of pd, there: http://prdownloads.sourceforge.net/pure-data/pd-0.36-extended2.tar.gz -replace your old pd directory with that new one (it is recommended to put pd directory under /usr/local/) -then donwload the source of the latest release of portaudio, there: http://www.portaudio.com/archives/pa_snapshot_v19.tar.gz -inside the portaudio directory(the one you have downloaded), there is a 'pa_mac_core' directory and inside there is the file 'pa_mac_core.c'. Replace that file inside the portaudio directory of pd and only that file. -then you need to create yourself two directory inside pd directory 'bin' and 'obj'. -finally go to your console cd under /pd/usr/ and do ./configure and make. let me know.

Serial Interface comport for NT and Linux
by Winfried Ritsch 22 Apr '03

22 Apr '03

Since we somebody asked, I have updated the comport external (serial interface) now that it works on Linux and NT. See: http://iem.kug.ac.at/pdwiki/index.php?ComPort http://iem.kug.ac.at/ritsch/programmier/pd_externals/ Needed help: Since I am no W!nd!ws-Guru: There is in the VC-Help mentioned that using this kind of ReadFile(...) function could block. Since I set the timeouts to zero it works ok on my machines. I have tried the Eventhandler-Wait-Stuff but didnt succeed with that. So PLEASE W!nd!ws-Gurus out there have a look at the code and correct it, if needed and send me a note (ritsch(a)iem.kug.ac.at). ...thanx in advance mfg winfried

yo pd peeps
by J. Scott Hildebrand 22 Apr '03

22 Apr '03

could any of you please comment on the current state of Pd, and in particular compared to the likes of Max, jMax, Spat, you name it. What are the approximate user-bases of each software package and how fast is each one growing? as far as expansions and externals are concerned, approximately how many does each package have? if you've used Max or jMax or something similar could you do a short comparison of them to Pd?
