I did it, haha xenharmonic synth
by Billy Stiltner 05 Sep '12

05 Sep '12

not shareable yet still workin out a few bugs left in from development and got 6 parameters to add to preset for the karplus strong string sim i added in at the last minute but i think it fits what i had in mind, it's been a long road and probably spurs from ideas i had as a teenager some 25 odd years ago like wondering how to tap my guitar signal into the yamaha dx7 for some fm feedback haha. here is for a listen of the current state of the synth http://soundcloud.com/woobleepblop enjoy some of it is playing on the keyboard and some is sequenced with my fractal sequencer.

installing Pd-extended on Linux (Mint 13) 64bit?
by Jared Nielsen 04 Sep '12

04 Sep '12

I'm trying to install Pd-extended on my Linux Mint 13 64bit without luck. I've tried the Slackware build, pd-l2ork, and a handful of other search results, each of which leads into errors that I then can't find solutions for. So, is there a recommended/straightforward route to installing Pd-extended? Thanks.

Re: [PD] RPI USB Audio -nogui "Invalid value for card"

hey miller. yeah on raspbian i got rid of the "invalid card" nag. no way to test stuff at moment via gui. all done via ssh on headless rpi. my guess is it has nothing to do with pd. usb cards have to be set to default. $ nano /etc/asound.conf pcm.!default { type hw card 0 } ctl.!default { type hw card 0 } $nano /etc/modprobe.d/alsa-base.conf change line: # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=-2 to: # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=0 m On Sat, Sep 1, 2012 at 7:13 PM, Miller Puckette <msp(a)ucsd.edu> wrote: > Hmm - no matter what I try over here I can't get Pd to complain > 'Invalid value for card' - a lame guess would be that either the > input or output only does mono and Pd is asking for 2 channels or > something like that. > > I suppose all works fine when you open Pd with a GUI, right? > > Thanks for your patience... > M > > On Sat, Sep 01, 2012 at 06:33:37PM -0400, m.e.grimm wrote: >> hey miller, >> >> > You can type "pd -nogui -audiodev 1" (1 is the default anyway) to get >> >> yeah that's what i meant.

pd-extended install from Debian mirror
by Matthias Braeunig 04 Sep '12

04 Sep '12

Dear list, how do I go about installing pd-extended for Debian Sid (unstable)? I can find packages for download here http://puredata.info/downloads/pd-extended/ but they are from the stable branch. I want a repository to include into my sources.list that is for sid. Or do I have to build the package as described on the Debian community page http://puredata.info/docs/developer/Debian/ ? Thanks, m

Hi everybody, is there anyone interested in translating PD FLOSS Manual to russian? I need some help with it. Even if somebody would provide just proofreading, it would be a great relief. Best regards, Lana

keycode dropped/use of curly braces
by Paul Gruendorfer 04 Sep '12

04 Sep '12

Hi, is there any chance to use curly braces (ASCII characters 123, 125) in pd? I initially wanted to use them in a message which I would like to send via OSC, but maybe there is another possibility to generate these? would be great to know, if so.. thanks! Paul

Readanysf~
by Pierre Massat 04 Sep '12

04 Sep '12

Dear list, I'm sending 3 messages related to the same project... 1) I'm using readanysf~ on a headless Rasperry Pi, running Raspbian, and it works mostly fine, except for short audio dropouts every once in a while. I don't know how to configure readanysf~, and I would like to know whether this could be a problem with the audio buffer. Increasing it would solve the problem ? 2) Using readanysf~ to read web radio streams, is it possible to know when a steady connection has been established (after all the redirections and trials), so that I can send [play( at the right moment ? My patch starts automatically, and for now I have hard coded a delay between the [open( and [play( messages which isn't always sufficient depending on the radio. Cheers, Pierre.

pointcloud in Gem (timbreID) and performance
by Max 04 Sep '12

04 Sep '12

hi list, william, this is a Gem recursion and glsl question. in the example patches for timbreID there is an interesting patch where the grains of a sample can be seen as a point cloud according to their parameters. this is done by parsing a long list for each point throuch a recursive gem chain using [zexy/repeat] it works very well up to 40 points (or a sample of up to 10 seconds). However, when you try to do this with a sample of 4.5 minutes it doesn't work any more because the list parsing and gemlist repeating for each and every point (then about 900) at framerates of 10 fps is to heavy on the CPU. William resolves this by rendering it once and taking a snapshot of the scene. that works nicely, but is not an option for my work, as i want to see the 3d space and navigate in it real-time. I was wondering if this could be done more efficiently and where to start. I think the points should be rendered in a glsl environment and the list of every points position should be static (in a matrice?) and not called and parsed by [list] objects at a rate of >9000 times per second. Unfortunately the geometry shader example doesn't work here, i was hoping to get some clues from there. william has a tiny image of a point cloud on his page: http://williambrent.conflations.com/pages/research.html#timbreID max
