synthesis
by Matthew Nish-Lapidus 07 Mar '03

07 Mar '03

hi, i've used pd a lot for sample/recording based audio work, and for video, but i haven't done much in the way of syntheesis. i've used reaktor for a lot of synth based work, but i'm interested in moving entirely to free, and more flexable, software. i'm just wondering if anybody has built any synth patches in pd and what kinds of synthesis you have used. thanks, matt.

[GEM] second screen
by chris clepper 07 Mar '03

07 Mar '03

Hi I just committed changes to the GEM CVS that add a message which sets the second screen mode for the [gemwin]. usage: [secondscreen 0/1( - to enable or disable the second screen fullscreen output. this flag has to be set before creating the gemwin. this should enable users without hardware acceleration on the second screen to at least use the main accelerated display for output. GEM does not work with un-accelerated hardware on OSX, and probably will never do so. you can either build from CVS or wait until the next binary update (this weekend at the latest). cgc

more gridflow screenshots a PureData patch to make 1-D cellular automata. the 8 checkboxes allows one to make the 256 possible 1-D automata that involve only immediate neighbour points. http://artengine.ca/jmax/gridflow/gallery/cellular_1d.gif big brother is watching you: http://artengine.ca/jmax/gridflow/gallery/vanishing_point_2.jpg a plot of the greatest common divisor function, color-corrected to make its features more apparent. white dotted lines correspond to simple fractions like 1/2, 2/1, 1/3, etc. black rows/columns correspond to prime numbers. http://artengine.ca/jmax/gridflow/gallery/gcd.gif http://artengine.ca/jmax/gridflow/gallery/gcd2.gif what was commonly called a shadebob long ago (adding the light of many very dim shapes): http://artengine.ca/jmax/gridflow/gallery/blob.png ________________________________________________________________ Mathieu Bouchard http://artengine.ca/matju

pd-iiwu from iiwusynth 0.0.6 to 0.2.1 results in zero output?
by Larry Troxler 07 Mar '03

07 Mar '03

Hi, yes I know I posted the iiwu~ object to begin with, so you might wonder why I'm asking the group this question. But the truth is, I just recently tried iiwu~ with version 0.2.1 of iiwusynth. Everything builds fine, as as far as I can tell, the new iiwusynth.h seems compatabile with the old one. If I set the synth VERBOSE creation flag, I can see that the note-on's are being received by iiwu. In short, everything seems fine, except there is zero output (by that I mean, the iiwu_synth_write_float seems to always write zeros). So, if anyone has alread tried building iiwu~ with a newer version of iiwusynth, could you let me know if it worked for you? Larry
