Re: [PD] Implementing "switch-and-ramp" technique to cancel discontinuities
by Frank Barknecht 03 May '07

03 May '07

Hallo, simon wise hat gesagt: // simon wise wrote: > That is: the whole example/technique described depends on the > assumption that the re-triggered sample starts from zero, it doesn't > make sense otherwise. Well, that's what's keeping me awake ATM: I believe in theory it is possible, to use the technique to also ramp to new values that don't start at zero. Assuming you have the old control value (envelope) end at time t0 at value "old[t0] and the new starts at value "new[t0]". The difference between the two is: "diff = old[t0] - new[t0]" Now the switch-ramp idea is this: You create a signal "ramp" that at t0 is exactly the difference between the two signals, and then you add this to the new envelops: ramp[t0] = old[t0] - new[t0] which gives: ramp[t0] + new[t0] = old[t0] without any discontinuity if new[t0] is zero or not. Then you let ramp[t] fade out to 0 so that after the fade, only new[t] is left. And now while writing this, I have found the error in my patch: I didn't do the "old[t0] - new[t0]" subtraction at all to get the ramp[t0] value! Because of that, it was of course only working if new[t0] = 0, because then ramp[t0] simply is equal to old[t0]. Attached patch shows switch and ramp correctly in action. Note to "hard off": Crossfading of course also works, however I was trying to understand the technique Miller describes. (Now I wonder, if the description in the book is complete. Miller, do you copy?) Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__

[OT] some tracks, pics of my exhibition
by Kevin McCoy 02 May '07

02 May '07

Hello list, In mid-April I had my senior exhibition here at the University of the South in Sewanee, TN (US). Trivia bit - this is Miller's hometown, his father taught math here (hope he doesn't mind me sharing that). The show was called "impuls liminae" and featured 2 installations and 3 pieces for headphones. You can hear the headphone pieces, all sounds made with Pd and arranged in ableton, here: "cyctast op i" http://art.sewanee.edu/mccoy/celinas/02.mp3 "elea (novean)" http://art.sewanee.edu/mccoy/blogsounds/elea_novaen.mp3<http://art.sewanee.edu/blogsounds/elea_novaen.mp3> "xaxado uHz" http://art.sewanee.edu/mccoy/blogsounds/xaxado.mp3 <http://art.sewanee.edu/blogsounds/xaxado.mp3> images of the show are here: http://pocketkm.blogspot.com/2007/04/senior-thesis-exhibition.html excerpt of the main 8-speaker install "yona nuki" is here (though it sounds tiny in stereo... just use your imagination) http://art.sewanee.edu/mccoy/blogsounds/yonanukiexcerpt.mp3 I wanted to say THANK YOU to the list for your excellent help and general good demeanor, it's been almost exactly 1 year since I started learning Pd and I have learned a lot from you all. Thanks, Kevin -- ++++ http://pocketkm.blogspot.com

Learning PD and creating a looper by example
by Chris Delahousse 02 May '07

02 May '07

Hey Guys, I'm relatively new to Pure Data and aside from a brief flirtation with Max/MSP, I don't have much experience with graphical programming. I've read the manual and understand the fundamentals, but I was wondering if anybody knew any good sites to learn with given examples and whatnot. My ultimate goal is to create a glorified looper with some forms of pitch recognition and sound synthesis. Does anybody know any well commented and easily understandable examples to help me out with this? Thanks _________________________________________________________________ Win a webcam!

Re: [PD] P4-optimized 0.40 vanilla precompiled for windows?
by Matteo Sisti Sette 02 May '07

02 May '07

I've read further and searched the archives of the list. Is this related to denormals? Isn't pd now handling denormals correctly? (that is, avoiding them) I mean vanilla 0.40. I ask that because I've seen discussion dating back to 2003 about this issue. Is it still an issue? Another thing I don't understand is why that is a problem only in pentium4: don't other processors have denormals as well? thanks m. ----- Original Message ----- From: "Matteo Sisti Sette" <matteo.sistisette(a)email.it> To: <pd-list(a)iem.at> Sent: Wednesday, May 02, 2007 12:36 PM Subject: P4-optimized 0.40 vanilla precompiled for windows? Hi, I'm having the "CPU jumps after a while" problem. That is, the same patch which at the beginning is consuming about 30% of CPU, after a while it is running (and absolutely nothing changes in it, and I am totally sure this is true) suddenly jumps to a CPU consumption over 70%. I've read in the archives it is an issue specific to Pentium4, and that there is an optimized version of PD that solves it. Is there a 0.40.x pentium4-optimized version of pd-vanilla precompiled for windows? If so, where can I find it?

Implementing "switch-and-ramp" technique to cancel discontinuities
by Frank Barknecht 02 May '07

02 May '07

Hi, I'm having a hard time implementing the "switch-and-ramp" technique to cancel out discontinuous control changes as described in Miller's Book at http://crca.ucsd.edu/~msp/techniques/latest/book-html/node63.html In attached patch I tried to build a very simple example of the technique in action (The Book lacks a Pd example as far as I see), however it only works if the discontinuity is one starting a zero again. Everything else actually amplifies the discontinuity instead of getting rid of it. Does anyone have an idea how to fix that? Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__

Control-edit syndrome

02 May '07

Hi, Has anyone of you ever experimented this? You are browsing the folders in your computer. Before you click on a file name to rename the file, you instinctively hit CTRL+E expecting your mouse cursor tu turn into a hand. Does anyone know a cure? (except abstinence from PD obviously) sorry - just kidding :) bye m. -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Vendi l'auto? La moto? La barca? Il Camper?
