So far, [vcf~] has done a great job, thanks! Being able to also change resonance at sample rate would be nice. At this point, building an object like that is a bit beyond my level of expertise.
IIRC the [moog~] object has audio rate control of all its parameters.
I am wondering, is there a distortion object around that can be controlled at sample rate? Both [dist~] and [overdrive~] give many clicks when real time control moves too fast.
Many object combinations can achieve this. [max~] and [min~] provide simple floor and ceiling clips adjustable at audio rate. More sophisticated methods are to use a [*~] scaling before a [tanh~] or [sin~] function, or to index a [tabread4~] containing a transfer you prepared. In this regard have a look at making Chebyshev function tables which have interesting properties when used for distortion.
Browsing the extra folder of pd-extended, I did not come accross other distortion or similar objects. Which also makes me wonder: is there a way other than google or browsing the pd files, to find relevant objects?
Yes.
- Use the help browser by category
- Use the resources on puredata.info
- Manually explore the /extra or /extern folder in your pd install
- ++ more ++
Bye, menno

Yes its useful to have signal control over resonance too although less common to need it. An example is if you make a string or drum skin model with parallel resonances and you want to dampen it when it's sounding.
Its been done before using [rpole~] and [rzero~] objects, but IIRC was unstable when sweeping the resonance and cutoff simultaneously. Filter topologies, with the same poles and zeros but in different orders, will behave differently when you vary the coefficients, so testing with envelopes on both controls should be done.

According to its helpfile, [vcf~ ] is the same as [bp~ ], but with a voltage controlled aka signal rate inlet for frequency.
Now let's say that I want to have all three inlets as signals.
Is there an abstraction for doing that ?
I just made part of one, by looking at http://crca.ucsd.edu/~msp/techniques/latest/book-html/node143.html
But I'm not done yet. Anyone interested ?
