The state saving system and dynamic gui modules are worth a look. I haven't delved in the rest yet.

Maybe should you have

[loadbang}
|
[float 6]

[until]

instead? Anyway, you can execute pd with the -noloadbang option to edit your patch.

Non-linear elements in the feedback path can be fun and do some interesting things but far from a general purpose filter, no clue if pd will play well with that sort of abuse.

In my humble experience: very well. I've been working on an "acoustic feedback" patch for a while now. With allpass/diffusion, peak filter and basic distortion in the loop, it was quite lively and convincing.

Thank you, it did work here too!

Hi,

Has anybody managed to get pd spectral toolkit working?
I'm especially interested in the GEM waterfall spectrum but alas, i get

pd-externals/SpectralToolkit/pd_spectral_toolkit.l_ia64: undefined symbol: _ZGVbN2v_exp
pd_spectral_toolkit: can't load library

on startup. make linux didn't complain about anything.

I love this feedback oscillator! I don't know how relevant it is, but it reminded me of https://ccrma.stanford.edu/software/snd/snd/fm.html [cascade FM: sin(sin(sin))]:

As z increases above 1.27, we get a square wave, then period doubling, and finally (ca. 1.97) chaos.

For example, I would like to trigger a sound playback multiple times
it layers the playback at that particular rate

You mean, like a polyphonic sampler? If so I'd load the sample in a table and have an instance of tabread~/tabread4~ for each "layer".

If you follow the algorithm in http://cgm.cs.mcgill.ca/~godfried/publications/banff.pdf, E(5,13) = 1001010010100, But if you use the much simpler one from @Stutter you get 1001001010010.

If you flip stutter's result three digits to the left you get banff's. It's a matter of a [- 3] somewhere.

If I had to buy something today I'd go for Intech EN16. Fighting my impulse buy a while back, I dug out my old dusty bcr2000, found out it had a software editor and could be set in absolute mode. And I don't need anything more.

With encoders set to absolute, no need for two-way communication, no more jumps in values, everything stays in the patch. I have a set of WIP abstractions that steal the focus of the shared unique controller, map and scale CC increments/decrements to the relevant patch parameters and deals with store/restore presets.

I just wish there were something to faders like what encoders are to knobs.

http://www.pd-tutorial.com/english/ch03s08.html was a great help for me back in time.
