Hi, I'm working on echo detection and looking for autocepstrum with pd. Is there any detail information about autocepstrum-cepstrum and it's output data for commenting about finding echo.

Automating startup
by Rick Bragg 12 Jan '13

12 Jan '13

Hi, I would like to set up my system to set up my patch automatically with jack and all the right connections when the system boots. I am using Ubuntu studio at the moment. I currently have it set so that qjackctl starts when I log in, and I set qjackctl to automatically start up jack server when it opens, and then to open my pd file after it starts. I have a few problems to overcome. First, every time pd starts, I need to go into the "Media" menu and change from "Default MIDI" to "Alsa MIDI" Why do I have to change this every time? Shouldn't this setting be saved? Second problem: After pd opens, I always need to go back to qjackctl, open up the the "connections" and change the MIDI connections. Can't I save this as a patchbay setting somehow? I tried that, but it doesn't work because the patchbay settings need to load AFTER pd starts otherwise the pd connections are not available. Are there any good documentation somewhere that discusses automating all this kind of stuff? Thanks! Rick

Using the keyboard to control motion of pdp_form (for a drawing machine)
by joao dos santos 11 Jan '13

11 Jan '13

Hello, I'm new to this list and I'm looking for some help regarding the control of the motion of an ellipse using a keyboard - 2 keys for x axis and 2 keys for y axis. When drawing using pdp_pen on a x11 window the keyboard doesn't act upon the pd patch. How can I control the ellipse motion using the keyboard? Can anyone help me with this? Thanks, João

Finding sample length of long aif
by Samuel Burt 11 Jan '13

11 Jan '13

Greetings list, I'm developing an application for someone that involves picking a start and end point of a selection of long (30 minute) audio files. I've solved this by using [soundfile_info] to find the length. I provide two sets of arrays. One displays the waveform of a selection set from the beginning of the file. A second displays the waveform of a selection set from the end of the file. This works great for wave files, however [soundfile_info] doesn't work with aifs. Does anyone know of another method of getting the length (and preferably number of channels) of an aif? Thanks, Sam

Pd-ext 0.43.4 Tcl Invalid Command Name error
by Marco Donnarumma 11 Jan '13

11 Jan '13

Hey, I'm keeping trying my patches with the new pd-ext to report back. >From time to time when launching my Xth Sense patch this error appears: (Tcl) INVALID COMMAND NAME: invalid command name ".x9c4d3b0.c" while executing ".x9c4d3b0.c create image 900 776 -image a4304c0PHOTOIMAGE -tags a4304c0PHOTO ("uplevel" body line 283) invoked from within "uplevel #0 $cmds_from_pd" as far as I can understand, it might be related to nested GOP subpatches. In fact, the GUI freezes (although data crunching still works). Then Pd can't be close (although still running properly), and you end up killing it. I've got GOP abstractions embedded in a parent GOP abstraction, and I load the latter into a parent GOP, which in turn is loaded into a subpatch. I know it sounds clumsy, but modularity like this works nicely for updating the whole software without changing the main patch. It worked perfectly fine with pd-ext 0.42.5. any idea if I'm doing something wrong, or Pd does? thanks! -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director.

Hi, with the latest Pd version, Pd uses the system language as standard. The thing is, I want to keep my Pd in english. How is it possible to set the language when starting Pd? Where can suggestions to the language be sent? Best, JoÃ£o

Cursor automation in pd?
by Sebastian Valenzuela 10 Jan '13

10 Jan '13

Hi everyone, I can't find the answer to this question anywhere. Is it possible to automate the movement and clicks of a mouse in pure data? Or maybe there is an easier way of doing what i'm trying to do? In my project, I am having pd sense a google talk phone call being made to my browser (Google Chrome). It will wait for one "ring", then I'd like it to move the mouse and accept the call on the browser. One problem I see with this is that it might stop once it clicks out of the patch..? I know there are other automation programs out there; I was actually working on some code in AutoIt to accept that call. But i'd like to do it all in pd, if possible. Thank you for your time, Sebastian
