Im on macosx 10.8.5 cheers R. 2013/10/24, peiman khosravi peimankhosr...@gmail.com: Hi Ronni, Yes, in fact that's exactly what I'm doing in the csound algorithm. I have a user-defined array, one array of bin amplitudes and one array of bin frequencies, both written from the analysis window. The thing is that you need to deal with the amplitudes too. Simply moving the frequency value from one bin to another doesn't work, because each bin can only represent a narrow frequency band. So you need to also move the amplitude content of the bin too.

This warp program is very similar to what im trying to achieve , but theres a difference in the way how frequencies are mapped.

At each iteration it should get the current frequency value of that bin, then i need to compare this value with my array of predefined frequencies and replace that value with the nearest value in my array. i hope its clear, cheers R. 2013/10/23, peiman khosravi peimankhosr...@gmail.com: Hello, If I understand you correctly, this is exactly what the GRM Tools plug-in Warp does. http://www.inagrm.com/warp I have a version of this which I made with pd and csound, which I'm attaching. The FFT is done in Csound. To run it just install csound6 and then open up the patch. I've also included the externals with the patch, but they are built for osx so you'll need to replace them if you're on a different platform. I know that the csound~ external is running on osx, but I've never tried it on windows so... If you want really precise control over which frequencies you're remapping then you need to change the pd patch a bit but it's just a question of converting bin number to frequency value, which is simple.

I think I'm almost immediately addicted to the splined patch cords. I'll

Re: [PD] Pd-l2ork running on OSX
Ok. Just playing around a little and noticed: * there are 2 Preferences menu options in the Pd menu, the first works and is a folder with further options while the second Preferences... doesn't do anything. * the Media menu has a couple empty sections with remaining separators where the Audio Midi settings options used to be * the put menu is empty when the main pd window is active, while Pd-extended simply greys out the menu options. The Put menu is then populated after selecting a canvas window. * the Search Browser works and is noticeably faster than the last time I tried it, but the search result links don't work for me. Navigating with links on the Home page do work. * I'm not a fan of the separate console window .. yet another window floating around, but that's not a huge deal * dosen't have the nice icon that pd-extended has :D also, pd-lork should consider using something similar to the nice About patch in Pd-extended. Oh, there are so many improvements in pd-lork! So nice. I hope most if not all of these make their way into vanilla. The gui performance is much better, although I like the Pd-extended main console window better. The patch cords are obviously nicer, although I like the straight lines in Pd-extended better with anti-aliasing off, however that's just a niggle.

Re: [PD] moog~ in pure pd?
Hmmm. I made a moog-style filter last year, but it's an external of course.
Totally ripped from source code I found elsewhere, but it may help if you look
at the algorithm for the filter's operation.
Note that this is an IIR not an FIR filter, so it can burst and screw up your
DSP chain (but only if you feed it bad values). Everything is signal-based -
i.e. cutoff frequency and resonance.
Cheers,
Ed

the undocumented 2nd output of vcf~ is a lowpass. and there are a few
methods to build the basic (cookbook) filters with pd-vanilla-objects:
you could use fexpr~ to make your own signal-rate biquad. it works very
well, but needs a lot more cpu than necessary. or you could use
cpole~/czero~. like in the beequad-abstractions. i have used the same
method in all my filters, with signal-rate. (in my instruments
collection on my homepage). of course this is still not exactly
moog~. it should be possible though to make a moog-abstraction
in the same way, but i have not tried (yet)...
maybe anyone else has already?
