Re: [PD] Nice distortion
Hallo, hard off hat gesagt: // hard off wrote: > most of the stuff that operator synth does looks fairly straight-forward, > shouldn't be too hard to put together a basic pd clone. I had a quick look at the Live manual, where I found, that Operator is just a 4-op FM synth with some additional tweaks. A simple 4-op FM is on my January TODO list for the RjDj library anyway. In general FM is easy, but the more operators you have, the more you want to use [mtx_mul~] from Iemmatrix, but RjDj only has vanilla objects. > challenging bits will be the square and saw waves with variable numbers of > partials, but i think that will probably just be a case of [tabosc4~] and > making some tables with sinesum values.

Yep, aliasing in FM always is tricky. It will be ignored for RjDj. ;( > the filters shouldn't be TOO hard, although to get a good lowpass, notch, > bandpass and highpass it might be best to dig through pd-extended's > externals. for lowpass i usually use [resofilt~] bandpass vanilla's [vcf~] > is fine, although franks new resonz~ / resonr~ filters look super > promising. for highpass, i prefer [svf~ high]. not sure about the notch > filter. I'm a bit proud of resonz~ and resonr~: In the end they look very simple, the hard part was digging J.O. Smith's Filter book. ;) I'll also do some version with signal inlets later. If anyone knows which transfer function would make a good 2 pole resonant lowpass filter (like lp2~ in Iemlib) I'd be super thankful.

[PD] Gem install problem on iBook G4
I am having trouble installing pd-extended on my G4 iBook. I am running Mac OSX version 10.4.11. I have also tried running it on a macbook (intel) running 10.5 which I borrowed from a friend. I used the respective versions of the pd-extended download for each. I need to be able to run Gem which is why this is a problem. The basic version of PD seems to work fine, just not the extended libraries. I also tried downloading Gem separately and connecting it via the path menu, to no avail. This is weird for me as I've gotten pd-extended to work just fine on a G4 desktop and a macbook almost identical to the one I recently borrowed. Any suggestions are greatly appreciated. Here is the printout from the last time I started up PD: libdir loader $Revision: 1.8 $ written by Hans-Christoph Steiner compiled on Jul 29 2008 at 04:03:05 compiled against Pd version 0.40.3.extended /Applications/Pd-extended.app/Contents/Resources/extra/Gem/Gem.pd_darwin: dlopen(/Applications/Pd-extended.app/Contents/Resources/extra/Gem/Gem.pd_darwin, 10): Library not loaded: /usr/X11R6/lib/libfreetype.6.dylib Referenced from: /Applications/Pd-extended.app/Contents/Resources/extra/Gem/Gem.pd_darwin Reason: image not found Gem: can't load library libdir_loader: added 'cyclone' to the global objectclass path libdir_loader: added 'zexy' to the global objectclass path libdir_loader: added 'creb' to the global objectclass path libdir_loader: added 'cxc' to the global objectclass path libdir_loader: added 'iemlib' to the global objectclass path libdir_loader: added 'list-abs' to the global objectclass path libdir_loader: added 'mapping' to the global objectclass path libdir_loader: added 'markex' to the global objectclass path libdir_loader: added 'maxlib' to the global objectclass path libdir_loader: added 'memento' to the global objectclass path libdir_loader: added 'mjlib' to the global objectclass path libdir_loader: added 'motex' to the global objectclass path libdir_loader: added 'oscx' to the global objectclass path libdir_loader: added 'pddp' to the global objectclass path libdir_loader: added 'pdogg' to the global objectclass path libdir_loader: added 'pixeltango' to the global objectclass path libdir_loader: added 'rradical' to the global objectclass path libdir_loader: added 'sigpack' to the global objectclass path libdir_loader: added 'smlib' to the global objectclass path libdir_loader: added 'toxy' to the global objectclass path libdir_loader: added 'unauthorized' to the global objectclass path libdir_loader: added 'pan' to the global objectclass path libdir_loader: added 'freeverb' to the global objectclass path libdir_loader: added 'hcs' to the global objectclass path libdir_loader: added 'jmmmp' to the global objectclass path libdir_loader: added 'ext13' to the global objectclass path libdir_loader: added 'ggee' to the global objectclass path libdir_loader: added 'flib' to the global objectclass path libdir_loader: added 'ekext' to the global objectclass path libdir_loader: added 'flatspace' to the global objectclass path /Applications/Pd-extended.app/Contents/Resources/extra/pdp.pd_darwin: dlopen(/Applications/Pd-extended.app/Contents/Resources/extra/pdp.pd_darwin, 10): Library not loaded: /usr/X11R6/lib/libX11.6.dylib Referenced from: /Applications/Pd-extended.app/Contents/Resources/extra/pdp.pd_darwin Reason: image not found pdp: can't load library /Applications/Pd-extended.app/Contents/Resources/extra/pidip.pd_darwin: dlopen(/Applications/Pd-extended.app/Contents/Resources/extra/pidip.pd_darwin, 10): Library not loaded: /usr/X11R6/lib/libX11.6.dylib Referenced from: /Applications/Pd-extended.app/Contents/Resources/extra/pidip.pd_darwin Reason: image not found pidip: can't load library /Applications/Pd-extended.app/Contents/Resources/extra/gem/gem.pd_darwin: dlopen(/Applications/Pd-extended.app/Contents/Resources/extra/gem/gem.pd_darwin, 10): Library not loaded: /usr/X11R6/lib/libfreetype.6.dylib Referenced from: /Applications/Pd-extended.app/Contents/Resources/extra/Gem/Gem.pd_darwin Reason: image not found gem: can't load library ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
