acid
by Chris McCormick 14 Aug '14

14 Aug '14

Hi, Another question in a very general vein. I asked this on the Csound list a while back (when i was using csound) with good results. I'm trying to produce an acidy type sound (eg 303) and having trouble as my current saw-tooth-through-a-vcf just sounds pretty wimpy. Any ideas on how to fatten it up a bit? I'm not looking for a perfect reproduction of the 303 sound, just a nice acid sound. Hints? Tips? Is there some place where people post interesting Pd patches they've created for others to download at try out? Should there be? Regards, Chris. ______________________________________________________ Chris McCormick - Systems Developer - PerthWeb Pty Ltd Internet Solutions for your business!

oops: ALSA cards not reported in order?
by Peter P. 04 Aug '14

Hi! Pd 0.45.0 informs me at startup that "oops: ALSA cards not reported in order?" while all seems to work normally. I also have this: cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xf8220000 irq 45 29 [ThinkPadEC ]: ThinkPad EC - ThinkPad Console Audio Control ThinkPad Console Audio Control at EC reg 0x30, What does the above warning try to tell me? best, Peter

Re: [PD] Legal restrictions for apps

Well, it seems like all the authors agree and there's already an LGPL license. I only brought up all of this due to the inconsistency between whats actually there in the source files. I'd love for that to just be changed and we all move on. It's not like this is a huge patent / money maker thing. If being anal and bringing this to light truly means I *can't* use it in the long run, well than I should have done what most everyone else does in these situations: use it and keep my mouth shut :P. We know what is allowed / not allowed by Apple, don't need a lawyer for that.

Re: [PD] udoo board sound issues

I've tried my both Roland Edirol UA-25 & UA-25EX and both work great. The dedicated USB controller makes these guys work as compared to an RPI where I can't get full duplex without tons of dropouts. I'm using a Linaro install which boots to the console and runs the PD through scripting. The speed is great as compared to my old wearable computer. 4 cores makes a difference. I had to recompile my kernel to add midi support, but that's working great. It's not too bad, actually. I also built Pd-vanilal from source which was pretty easy using ./configure + make. I also have a script which fetches externals and builds/installs the agains vanilla so I have the few externals I need. As with my previous experience running Pd + embedded Ubuntu, I get great performance with RT permissions, the -rt startup flag, and ALSA. Jack is needless overheard unless you want to work with other Jack-enabeld apps. Same with X windows, although my setup was running great in X with pd + ALSA in testing. From your description, it sounds like your main issue is jack & pd are probably not running in realtime. I can sent you my install notes if you want (or put them online, as I've been meaning to). Also, are based in the NE within driving distance to Pittsburgh? We could do a patching circle/UDOO setup afternoon :D On Mar 9, 2014, at 5:14 PM, pd-list-request(a)iem.at wrote: > From: Miller Puckette <msp(a)ucsd.edu> > Subject: Re: [PD] udoo board sound issues > Date: March 9, 2014 at 5:07:54 PM EDT > To: Simon Iten <itensimon(a)gmail.com> > Cc: PD list <pd-list(a)iem.at> > > > H iSimon - > > I haven't tried any but the built-in yet but I have a few USB interfaces > around here that I can try.

How to get a list of midi devices without GUI
by Antoine Villeret 02 May '14

02 May '14

Hello, I'm wondering how to get a list of midiout devices without GUI. This has to work without GUI. I tried [mediasettings/midisettings] but it always report 0 devices (both in and out) when there is no GUI. i also know the -listdev option to Pd, but this only list devices in console, and I need to proccess the number in the patch. I observe this on Linux (both Ubuntu 12.04 64bit and Raspbian (kernel 3.10.25+) with pd 0.45-4. But it seems to be OK on MacOS with pd 0.45-3. Thanks Antoine -- do it yourself http://antoine.villeret.free.fr

literal $0 from message to gui send and gui receive
by Billy Stiltner 17 Apr '14

17 Apr '14

hey, I have been trying to rename sends and receives of dials at runtime they need actual literal $0 in their name. so I tried this with sending a 0 to $$4 in a message it worked for the literal renaming but the patch gets messed up after saving and reloading. somehow the patch does need to be able to be edited and saved without changeing the $$4 to a $\$4 once reloaded after a save. this is what the patch looks like from the .pd file after a save. #X msg 188 -194 \; \$1-o\$2-waveform-rx receive \$$4-o\$3-waveform-rx \; \$1-o\$2-dt-rx receive-rx \$$4-o\$3-dt-rx \; \$1-env\$2-o\$2-dt-rx receive \$$4-env\$3-o\$3-dt-rx \; \$1-lfo\$2-o\$2-dt-rx receive \$$4-lfo\$3-o\$3-dt-rx \; \$1-o\$2-pw receive-rx \$$4-o\$3-pw-rx \; \$1-env\$2-o\$2-pw-rx receive \$$4-env\$3-o\$3-pw-rx \; \$1-lfo\$2-o\$2-pw-rx receive \$$4-lfo\$3-o\$3-pw-rx \; \$1-env\$2-o\$2-rx receive \$$4-env\$3-o\$3-rx \; \$1-lfo\$2-o\$2-rx receive \$$4-lfo\$3-o\$3-rx; #X msg -109 -193 \; \$1-o\$2-waveform-rx send \$$4-o\$3-waveform \; \$1-o\$2-dt-rx send \$$4-o\$3-dt \; \$1-env\$2-o\$2-dt-rx send \$$4-env\$3-o\$3-dt \; \$1-lfo\$2-o\$2-dt-rx send \$$4-lfo\$3-o\$3-dt \; \$1-o\$2-pw-rx send \$$4-o\$3-pw \; \$1-env\$2-o\$2-pw-rx send \$$4-env\$3-o\$3-pw \; \$1-lfo\$2-o\$2-pw-rx send \$$4-lfo\$3-o\$3-pw \; \$1-env\$2-o\$2-rx send \$$4-env\$3-o\$3 \; \$1-lfo\$2-o\$2-rx send \$$4-lfo\$3-o\$3; ------------------------------

[OT] Pd to play sounds simultaneously on 8 speakers with cheap computer
by Jack 01 Apr '14

01 Apr '14

Hello, Is it possible to use BeagleBoard, Raspberry Pi, Udoo or others without dropout with this configuration : 8 IR sensors 1 BeagleBoard (or Raspberry Pi, or Udoo or others) with Pd and linux 1 sound cards with 8 output 8 speakers like this : 8 IR sensors -> Beagleboard -> sound card -> 8 speakers (so it is possible to play 8 sounds at 44100 Hz 16 bits *simultaneously*). If yes, can you tell me which model of sound card works well with these cards ? Thanx. ++ Jack
