Extended installers feedback: win/osx/linux
by derek holzer 28 Feb '06

28 Feb '06

Hi HC and the gang, I just gave a PD workshop at Denver University. There were three or four Windows users, almost a dozen Mac users with various versions of OSX 10.3 or 10.4 and one Debian user. Only one had any previous experience either installing or using PD. This was a pretty typical workshop group in my experience in terms of both platform and experience levels, although I would assume that out in PD-UserLand you would find Linux users much better represented demographically. As an experiment, I had everyone use the extended installers to see if it would save us some time. In the past, installation has often taken up a full day or more depending on architecture and whether or not PDP is being covered. Some feedback: 1) Windows * Pd-0.38.4-extended-RC8.exe installer * Installation seemed fine. * Gem and many other windows-supported externals seemed OK * [joystick] refused to load * [playlist] refused to load * Not enough time to test all externals * This installer probably saved a lot of time over the MSP installer because of the included externals. I'll continue to recommend it for windows users. 2) OSX * Pd-0.38.4-extended-RC8.dmg * PDP copied from Pd-0.38.4-extended-RC5.dmg (I made the install CD for the workshop before HC updated the RC8 installer). * As I've reported several times before, the GUI ranges from slow to unresponsive. The -nrt flag does seem to help fix this problem, although I'm not sure if that means more audio glitches or not. The only other workaround seems to be to reduce patch complexity and the number/update times of GUI elements. * [hid] broke down frequently for several workshop participants, particularly when opening the help patch. It has worked flawlessly with the 0.38.4-extended-RC8 for me under 10.4.4-10.4.5, so I cannot explain why it instantly crashed for others. We tried it primarily with Logitech and Sidewinder joysticks. * PDP did not get the testing it needed because most participants neglected to install X11. * I'd like to be able to factor "user error" into some of this (with [hid], for example), but we really all went through the same install together, including copying over the proper plist file. So I really don't know. Maybe different OSX versions? I won't be seeing most of these students again, so I won't have time to individually troubleshoot and make bug reports for each situation. Sorry... * As a side-note: in contrast to what Sara Kolster and I reported earlier, her old 0.37 installer was slow/unresponsive when audio processing is turned on, and sound breaks up even in a patch with only three objects, one GUI element and a MIDI input. Sara uses 0.37 for Gem only, which works fine with the 0.37 installer but is unresponsive with the 0.38 ones. * I still find the terrible response-times of the GUI the biggest problem to work with under OSX, with the unpredictability of [hid] coming in a distant second. * In general, however, using these installers saved me a tremendous amount of time on OSX. Thanks! * I don't think that time would be saved if OSX workshoppers had to get PD+friends from Fink or Darwin-Ports (I recall long ago having to get people to install Fink just for PDP/PiDiP!), but if a non-Aqua interface would speed up the PD GUI under OSX I'd support further investigation into that. Perhaps a DMG installer based on such a Fink/Darwin-Ports compile would follow on the heels of committing PD to one of these package manager systems? 3) Debian/Linux * Pd-0.38.4-extended-RC8-linux-i686.tar.bz2 * This participant had problems with the Debian and DeMuDi packages for Gem, and Jack support was also missing, so we used HC's installer. * Most externals tested seemed OK. * I can't recall if JACK support worked, I'll check back on Monday. It would be good to make sure it's compiled with both Jack and ALSA-MIDI support. * Gem did not work--the library refused to load. Using "locate", we could not find a Gem.pd_linux or gem.pd_linux anywhere on her laptop. Only gem_counter.pd_linux appeared in a search for "gem". Has it actually been included? * PDP seemed OK, more details soon. * I'll be testing her laptop again on Monday, so more specifics will be available then. * Once Gem works, and if Jack/ALSA-MIDI is there (apologies if I missed it!), this installer will also save a ton of time during workshops. * Can anybody suggest an x86 Linux liveCD with a full PD installation that actually works? By this I mean fast OpenGL/3D/Accelerated Graphics drivers, Jack, ALSA-MIDI and externals without broken dependencies (all problems I've encountered with live CDs + PD before). I'm guessing the Apodio one might be the ticket, but I'm still open to suggestions. Isn't Apodio only in French? I hope this is feedback you can use. Again apologies for less-than-specifics at times, but with 15 people in a two hour session there's just not much time for it. All in all, thanks for keeping these going HC! best, derek -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 130: "Question the heroic"

1000% distortion in pd in linux
by hard off 27 Feb '06

27 Feb '06

i just installed linux, and got a few things going now....pd works, audacity works, aplay works.... but aplay and audacity both play things fine, while pd seems to be playing my signal 1000 times to loud....i have to put a [*~ 0.0001] object before the dac~ to avoid serious clipping leading into total distortion. same problem with the hydrogen drum machine, it seems. any clues???

Displaying MIDI Note Names
by mark edward grimm 27 Feb '06

27 Feb '06

Hi List: I'm trying to figure out how to display "MIDI Note Names" (C#, Bb, F#). I've done several searches of the list, google etc but have yielded no concrete results. I know that in Max all you need to do is do "Get Info" on a number-box and change to "MIDI Note Name" but I have failed to find that option in PD. Thanks for the help!

Re: RE : [PD] Gemmouse inlet?
by B. Bogart 27 Feb '06

27 Feb '06

Hi Carlos, Ok, I found the patch, I only tested in on OSX, but it should work fine on linux/windoze, maybe with a little tweaking here and there. Anyhow I'm CCing the list again so everyone else who wants can get the URL from the thread. www.goto10.org/~bbogart/gemwin-interaction.tgz You can see I'm doing some strange things here with the scale, since the scale of the object changes, I need to know its changed bounds in terms of gemunits. This is why I had been asking for simple collision detection in Gem, so that you could just ask if the rectangle intersects with a single point on the XY plane, and not have to manually calculate the bounds based on the scale change... I have not looked at that patch in years. .b. Carlos Caires wrote: > -----Original Message----- > From: B.

Yo, If you want to do a 'downsample' check out the built-in [samphold~] object. If you put a slow squarewave into the right hand inlet you can get nice bitcrunching. If it's not time-domain quantising that you want to do, but would rather 'alias' the wave - reduce the resolution of the wave in terms of the number of unique positions that a sample can be in vertically (e.g. '16 bit', '8 bit', '4 bit' etc.) at each sample point, then try out the builtin [wrap~] object. If you want GOP abstractions that do these two things check out: <http://mccormick.cx/viewcvs/*checkout*/s-abstractions/s-bitcrusher~.pd> <http://mccormick.cx/viewcvs/*checkout*/s-abstractions/s-fuzz~.pd> Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx

display waveform in GEM
by derek holzer 27 Feb '06

27 Feb '06

Following an idea from Gerhard Daurer, I'd like to look into displaying the waveform of an audiofile in a Gemwin. Gerhard sent me a prototype of a very cool patch combining my Particle Chamber with PMPD and GEM, which uses physical modelling to visually control the granulation of a soundfile. (And I hope he posts this same prototype here soon!) In his version, he has only a set number of audiofiles to choose from, so he simply loads a JPG of the waveform into the Gemwin. However, I'd like to be able to load any wav file into this and get some visual feedback (i.e. be able to see the peaks). This would be a one-time operation, and not something that would be changing in realtime (except maybe a zoom in and out), however I would like that displaying the peaks doesn't interrupt audio processing (as drawing a table would). I'd like to use GEM for this so that the various grains could be graphically represented on top of the waveform. I'm open for PDP implementations, but I don't really consider PDP cross-platform so I'd rather stick with GEM. Any Gemheads out there have an idea of how to go about this? best, d. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 82: "Honor thy error as a hidden intention"

8 bit, 4 bit sound
by \js 27 Feb '06

27 Feb '06

hi i know there's a way to cut down the sample granularity- down to even 2 bit, with pd, and i think it's even been discussed in this forum not too long ago- but i can't find it. can anyone remind me of how to 'downsample' like this? -- \js [ http://or8.net/~johns/ ]
