WAV format
by Jeffrey Hildebrand 03 May '04

03 May '04

i'm having trouble figuring this out. can somebody take a song and get a printout or text file of samples? like take a WAV file and then get a file from that because that would really help me with my research. thanks, scott

PiDiP rec~
by Ian Smith-Heisters 03 May '04

03 May '04

Howdy, I've got an issue trying to record from my Logitech Quickcam Pro 4000 with pdp_rec~. I put pdp in its own thread, open /dev/video0, create a window, hit the [metro 40] and the image shows up fine and pretty. I then send "compressor raw" to pdp_rec~ and open ./001.mov then hit start. I then get a long list of this: quicktime_encode_video_stub called pdp_rec~ : error writing frame : ret=1 Tried it with "compressor jpeg" too and I got a crash and segmentation fault. I also tried putting pdp_affine in between v4l and rec~, with no effect. I also tried the help patch for pdp_rec~ with the same results. I can live for the time being without this object if I have a way of capturing sequential frames as jpegs, but I can't find an object in the pdp reference that does that. Maybe there's some way of just writing packets to an array? Thanks, sorry I'm having so many problems these days. I'd make y'all cookies, but they'd get stale in the mail. -Ian

problems with PdVst
by smoerk 02 May '04

02 May '04

we tried PdVst with Ableton and Audiomulch. Ableton doesn't recognize the PdVst plugins. I know that it doesn't work with VSTi plugins, but with "SYNTH = FALSE" it doesn't recognized, too. With Audiomulch it sound choppy, like samples are missing. Even a patch where only adc~ is connected to dac~ does not work. We tried it on Windows 98.

cyclone for OS X?

02 May '04

Is there a version of Cyclone for OS X? going to the page http://suita.chopin.edu.pl/~czaja/miXed/externs/cyclone.html, there are linux binaries, which I am assuming do not work for mac.... To get cyclone running will I need to compile the source code myself? david

Paradiddle- passing symbols, not numbers
by Andreas Niemand 01 May '04

01 May '04

I am currently exploring paradiddle for pd. My idea is to set up a paradiddle-gui for a video mixer via gem/pd. As my understanding for paradiddle goes, I assign a name to a gui-element in interface-builder and receive those messages within pd. My problem is: Via numbers and bangs or toggles I can react in pd on numbers or switches (true/false). But how can I receive strings sent from paradiddle to be recognized by pd ? How can I assign names to objects that can deal with strings ? Einen wunderschoenen Tag wuenscht Andreas http://www.ein-schoener-tag.de - Dinge des Alt-Tags.

That's why i need to launch a new shell to do so (the pd one is busy running pd) i thought about osascript, but i want to make sure there's no other option. it'd be so handy to do that from pd... any thoughts? r -------------------- %evol--------http://www.mego.at/evol.html %alku--------http://personal.ilimit.es/principio %imbécil----http://imbecil.net
