[PD] Csound opcode Moogladder to Pd
I now made a version where cutoff and resonance are signals. This version is a bit more CPU intensive now, as some computations had to move into the DSP loop to react to the changes in center frequency. Awesome! To my ears it sounds great - very close to the Csound-version. I played a bit with a rational tanh approximation from the music-dsp list but it didn't sound good anymore. If someone wants to play with other approximations e.g. table lookup: Just change the function mytanh. Some optimizations are needed for reducing cpu load, true, I'll look into it. The filter response gets nasty and loud if the center frequency is near or above the sampling rate. Maybe it should be restricted as well. But then, resonance at 1 will make everyone jump, too... Yeah I noticed that aswell. I think the Csound-version has cutoff restricted to 0...1, which is 0...11050 in hertz. Thanks again. /Anton ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Only resonance is restricted to 0 and 1. It is in the pd version as well. I made some tests now and it seems it's not the cutoff frequency alone that makes the filter run wild. With resonance set to 0 a cutoff of 96kHz when running at SR = 48kHz doesn't go wild. But set resonance to 0.1 and it runs away. So in the end I'd say, just be careful and if in doubt [clip~] your input values. Another issue may be denormalization, so some PD_BIG_OR_SMALL checks could be useful.

Would it be worth feeding your patches into Hans's, and then any other abstractions I make/find I can also feed into svn? just out of curiosity: ~.pd, ~.pd, sgn~ and what else in zexy are already pd-vanilla abstractions (some of them are both abstractions and externals for performance reasons); is there an advantage in collecting these things in yet another arbitrary (as opposed to grouped by functionality) library? I think I kind of addressed this in my reply to Patrick, but I find the current situation with libraries of abstractions and externals a bit unsatisfactory. It would really be better if we separated out the storage layout (svn) and the user presentation bit, so that users could group externals/pathches by tag, or some othe non-hierarchical/non-exclusive grouping.

I guess (maybe) what i'm talking about isn't possible with svn alone. I think that using svn as 'user' tool for organising patches for download is a bit clumsy. What I would like to see is some kind of database-driven solution where patches can be tagged etc. That way you could maintain a netpd tag, which included patches that you don't necessarily maintain in your repository. Likewise you could have patches that you do maintain in your repository tagged purepd. I would be very happy to set something like this up. I was a big fan of the pdb that (Iohannes?) set up, and it woudl be great to do a pdb 2.0, with more of a web 2.0 flavour.

The setup function is the only symbol that needs to be exported.. You can also do it using MinGW (pd-extended is built that way) but I haven't yet found the patience to jump through all the hoops to get it working. Cygwin's gcc should work as well for externals. I'd like to try to make a stereo version of moogladder~ and also try tanh optimizations to reduce the cpu load. I'm not sure tanh can be optimized much more. If your CPU has a floating point unit built in, which they all do nowadays, that ought to be the fastest way to calculate it apart from having a huge lookup table. If tanh(x) = (e^x - (1/e^x)) / (e^x + (1/e^x)) the e^x only needs to be calculated once, a = e^x, then b = 1/(e^x), then tanh = (a-b)/(a+b). I would imagine that the FPU already does it that way but I don't know. Probably it could be approximated faster, but isn't the idea to have the most accurate value?
