vst~ for OSX, any update?
by Pagano, Patrick 13 Feb '14

13 Feb '14

Hello I am asking if anyone has had any success on updating the vst~ object for OSX. I would really like to use some simple vst~ plugins with GUIs inside of Pd, but i cannot seem to get the GUI window to pop up still. Pd sees all the information, ins/outs and methods but cannot display the GUI interface so it seems. I am building and extension to the Console abstraction Leonard made some years ago and i would like it to have interchangeable vsts for REVERB/DELAY/FILTER AND a wildcard effect. please help pp Patrick Pagano B.S, M.F.A Audio and Projection Design Faculty Digital Worlds Institute University of Florida, USA (352)294-2020

Malinette - rapid prototyping and learning
by abel.jerome＠free.fr 13 Feb '14

13 Feb '14

Hi all, We released a new version of the Malinette : http://reso-nance.org/malinette/download/ Malinette is an all-in-one solution, a rapid prototyping tool to show and make simple interaction and multimedia projects. It is a software and a hardware set. The software is based on Pure Data extended. It will be (one day) also a very convenient suitcase with a computer, speakers, arduino and electronic circuits to test ideas and projects very quickly. Best, Jérôme http://jeromeabel.net http://reso-nance.org

new [list tosymbol] / [list fromsymbol]
by Roman Haefeli 11 Feb '14

11 Feb '14

Hey Miller This is a quantum leap for Pd. This extension to the [list] family opens a whole lot of new possibility. Thanks for including it into the upcoming Pure Data. And thanks to Chris McCormick who I believe provided the patch. As a native German speaker, I had to try it out with ä ö ü, of course. [list fromsymbol] gives me '-61 -92' for ä. Is there a reason it outputs signed numbers (-128 to 127) instead of the (supposedly more common) byte representation (0 to 255)? [list tosymbol] deals with both the same way. Both '-61 -92' and '195 164' return an 'ä'. Roman

how to specify literals as type t_float
by katja 11 Feb '14

11 Feb '14

Hello, When working on parabolic interpolation in a Pd class, I wondered again what is the best method to specify literal constants as Pd's type t_float (which could be float or double). The interpolation goes like: ... t_float a = buf[peakindex-1]; t_float b = buf[peakindex]; t_float c = buf[peakindex+1]; t_float realpeak; realpeak = b + 0.125 * (c - a) * (c - a) / (2. * b - a - c); ... Without float suffixes for the literals, single precision t_float variables would be promoted to double here, which would be an unintended waste of CPU cycles. For some time, I've worked around this by using const variables instead of literals, like: ... const t_float two = 2.; const t_float eighth = 0.125; t_float a = buf[peakindex-1]; t_float b = buf[peakindex]; t_float c = buf[peakindex+1]; t_float realpeak; realpeak = b + eighth * (c - a) * (c - a) / (two * b - a - c); ... While this avoids redundant type conversions, it clutters the code and does not result in such fast instructions as literals do. Therefore I am now using type casts where type specifiers are normally used: ... t_float a = buf[peakindex-1]; t_float b = buf[peakindex]; t_float c = buf[peakindex+1]; t_float realpeak; realpeak = b + (t_float)0.125 * (c - a) * (c - a) / ((t_float)2. * b - a - c); ... For the above code I have checked assembly output as generated by GCC with -O3 optimization on Linux i386. Using literals without type specification, the whole routine is done on the FPU (80 bits precision). With the literals cast to t_float, it is done with single precision instructions for XMM registers. As far as I can see, casting literals to t_float results in the same assembly output as using the float specifier. For single precision t_float, '(t_float)0.125' is equivalent to '0.125f'. I can't think of a disadvantage, but let me know if I overlooked something. Katja

Is open source better?
by Pall Thayer 11 Feb '14

11 Feb '14

I'm giving a presentation this week. In a way, it's a counter argument to a recent presentation on Max/MSP. One of the things that I want to highlight is the "open sourceness" of PD. libpd presents a very good argument and I'll be highlighting a project I was involved with that produced an IOS app that used libpd as the audio engine. Is there anything else I should be considering besides the obvious points of open source being open source. Concrete examples of PD's open sourceness trumping proprietary technologies? Thanks, Pall -- ***************************** Pall Thayer artist http://pallthayer.dyndns.org *****************************

Infinite Permissions Loop
by Wesley Boynton 11 Feb '14

11 Feb '14

Hello, all! I am currently using PD-Extended in both OSX 10.8 and 10.9 environments. On our administrator accounts, we installed X11 and everything went fine. It launches and all is well. However, in our primary user accounts, we're greeted with a "You don't have permission to use the application 'Pd-extended'" dialog. Repeatedly. No matter how many times I grant it permission on an always or one-off basis, it continues to pop up the same dialog until I surrender and click "OK." This is, by the way, all despite the fact that PD and X11 are on the list of Parental Control-Approved applications for use. Any input would be extremely appreciated and valuable. -- ~Wesley Boynton http://www.wesleyboynton.com CELL: 703-635-0839

LyonPotpourri 3.0 and 64-bit Pd
by Eric Lyon 10 Feb '14

10 Feb '14

As a convenience for Pd users working with Pd compiled for 64-bits, I have provided compatible code for LyonPotpourri 3.0, which may be downloaded here: http://disis.music.vt.edu/eric/LyonSoftware/Pd/LyonPotpourri/ Users will need to build the externals themselves (typically by typing "make"), which should be a painless process on Linux and Mac. Cheers, Eric
