Is this possible in PD?
http://zynaddsubfx.sourceforge.net/doc/PADsynth/PADsynth.htm
this is an algorithm used by zynaddsubfx (a softsynth) to create nice sounding pad synths..
it seems like something that could be done in PD. While i think i get the basic Idea of what he's doing... I don't really understand the code that he has there. And have no idea how I might go about turning it into a pd patch
anyone care to point me in the right direction?
Sounds interesting, don't have time to work with it now but I do have a simpler string pad abstraction that uses random harmonics in conjunction with the tabosc4~ object. That's the object you'll want to use to do wavetable synthesis.
It's first inlet accepts a signal which corresponds to the frequency you want played. The second inlet accepts a phase. There is 1 creation argument which corresponds to the transition time in ms between the randomized wavetables. The default is 1000ms.
The way it works is it uses two tables. While one is being played the other is randomized and then it fades between them.
hmm. no sound though

Try ti with this
Was quite intrigued by this algorithm so I whipped an implementation up. Took me a while but I got it mostly right. Well... got something working. Haven't actually checked out the original to see how it compares.
There is one big difference though. I use a block size of 512 samples and fix the fundamental frequency to that size (comes out to about 86.13Hz). Then I scale the amplitude list proportionally to an arbitrarily chosen base frequency and the played frequency. This way it's easier to work with tabosc4~ and at 512 samples the computation time is short enough to play live (raise the sampling rate to get better results).
Requires PD-Extended and you need to unzip it onto your path.
On Mac OS X it would look like this:
~/Library/Pd/zynpadsynth/help-zynPadsynth.pd
~/Library/Pd/zynpadsynth/relF.pd
~/Library/Pd/zynpadsynth/waitblock.pd
~/Library/Pd/zynpadsynth/presets/melow.txt
~/Library/Pd/zynpadsynth/presets/reed.txt
~/Library/Pd/zynPadsynth.pd
~/Library/Pd/zynPadsynthGUI.pd
Open zynpadsynth/help-zynPadsynth.pd
Let me know what you think.
New version. Now supports arbitrary blocksize (Default 64)
Sorry people. Completely botched that zip. Sent parts of the new version with parts of the old one. Here it is. Should work at any block size less than 8192
Oops! Looks like something went wrong!
