Re: [PD] Pitch envelope
What I would do is use your typical sound playback algorithm, ([phasor~] feeding [tabread~] and relevant arithmetic. But take a side chain from the [phasor~] to another [tabread~] via a [*~ 1](or whatever length). and draw your pitch curve into an array (with it's length in that [*~] and with a y range of something like 0 - 2). sending the output of the second tabread back to the phasor(which should happily change it's speed sample-by-sample without losing it's position) by a multiply (from your original speed calculation.Something like...[O] |[arraysize sound] | \ | [s sample_length][expr 44100 / $f1] | |[r pitch_curve] |/[*~] |[phasor~] | \ | [s phasor] | | [r sample_length] | /[*~] |[tabread~ sample] |\[dac~][r phasor] | | [O] || | [arraysize pitch] | /[*~] |[tabread pitch] |[s pitch_curve](I've put that together quickly and in the middle of the night, might well have made a mistake or two)Of course, while this will change the speed of playback based on the position of playback, it is very difficult to express it as musical pitch differences. setting the scope of your pitch curve to 0 - 2 means that by multiplying it by the 'correct' playback speed you can go down to no movement at all (which will probably stall this sytem) and all the slow speeds related to this and up to twice the original playback speed (one octave above). Which will be good for creative sound, as I say, hard to scale as semiquavers.Andrew Date: Sat, 12 Feb 2011 00:00:57 + From: morph_2...@yahoo.co.uk To: pd-list@iem.at Subject: [PD] Pitch envelope So...

How can this be solved and be able to load the patch from the start without repeating this exercise of opening the examples, etc? it has been discussed a 100 times on this list. you either have to load iemmatrix as a single library (that is how it is intended; unfortunately PdExtended doesn't ship iemmatrix as a library, but only as single objects, that have a lot of trouble with special characters like *), or you have to load mtx_mul beforehand. luckily, you don't have to open the help-patch, but you can simply create a [mtx_mul] object. Alternatively, you could put [import hexloader iemmatrix] in your patch and then [mtx_*] and the like will be loaded without troubles. Unfortunately, hexloader which is supposed to fix this kind of loading problems is _not_ loaded by default in Pd-extended.

[PD] [PD-announce] Call for papers and workshops: Pure Data Convention 2011
Paper draft submission: March 28, 2011 Notification of acceptance: May 16, 2011 Final Paper submission: July 11, 2011 The 4th Pure Data Convention will be held August 08-14, 2011, at Liszt School of Music and Bauhaus-Universität in Weimar, Germany. In custom of the previous conventions we invite you to submit your papers related to the Pure Data programming environment in the fields of computer science, artistic creation and scientific research. The papers will be rated according to academic standards such as novelty and relevance in a peer review process. The Pd community is a heterogeneous group of users, developers, authors, artists, musicians, programmers; often in more than one role at a time. Papers from widely divergent perspectives are encouraged. Some possible topics could include: • Libraries and externals extending Pd • Tools built in or for Pd • Education • Spatialisation • Pd on mobile devices • Pd embedded in games and applications • Pd as a framework for audiovisual works Please check the website for the of terms of submission. Templates for the Papers (LaTeX, Open/LibreOffice) will be provided soon on the conventions home page: http://www.uni-weimar.de/medien/wiki/Pure_Data_convention_2011 The conference is held in English, thereby the papers have to be in English. The length of a paper should be 4-8 pages, including an abstract (50-100 words) and up to 5 keywords. Proposals for workshops of all levels, from beginner to special interest, may be directed my email to max.neupert at the domain uni-weimar.de A separate call for music, performances and artworks will follow soon. Please feel free to forward this email to anybody who might be interested! The PureData Convention 2011 organization team.

Re: [PD] Sigmund~ and tracks.
Hi Julian, I just looked at the patches and I hear what you're talking about now. The erratic changes are because it's really hard to get nice smooth tracks by analyzing this kind of signal. With violin samples I got useable results, but the rougher timbre of your viol has a lot of high frequencies that emerge and disappear unpredictably. I think that getting 48 stable tracks out of it is probably a lost cause...even with only 10 it was pretty bad with sigmund~'s default settings. The only way I could imagine improving things is to use the flag that shows up with each track list to indicate whether it's a new track or a continuation of an old one. With that information, you could try fading in new tracks on free oscillators in the bank to avoid the sudden discontinuity when frequency jumps by a huge amount. Data from a continuing track could safely be sent to the same oscillator. I guess you could also EQ it to get rid of those unpredictable high frequencies - I plotted the spectrogram and the most troublesome ones are above 2500Hz. Of course, that would also put a big damper on the timbre you're interested in... I wish I had a great solution for you, but this is a tough one. Assigning frequencies to specific oscillators in your bank based on track flags really seems like the best bet.

From sigmund~ it goes into '[pd sine_output] then thrown to [sines] which has a switch~, top right. I'm using GEM and MSD to create a 'swarm' which has the partials mapped to it so I haven't included my output~ as that would mean including loads of extra files. So you will need an output~ to [catch~] the 2 track [throws~] [throw~ revsound_L] [throw~ revsound_R] I suppose it's quite possible that as your not receiving any pan info the audio will be stuck either left or right anyway? What I was trying to achieve with the [attdec_gen2] inside [sine_rev_gen_2] was a simple attack and decay but what is happening is that they are being triggered all the time, aargh. I would really like the amp and freq from sigmund~ to be as quick and as smooth as possible, so any assistance with that will be hugely helpful.
