For the record, the current SVN of Ingen (http://wiki.drobilla.net/Ingen) already supports LV2, so what we want might already be built.
I still want to explore the whole "compilation of circuits with linear and non-linear properties" though, since that's an area unexplored in the open source world.

Re: A draft whitepaper of my parameterization idea
Well, the LV2 spec is certainly flexible enough to allow for the idea to work. RDF is still kinda alien to me, but I suppose I can get it eventually. As for "circuits" and such being tongue-in-cheek, I pretty much knew that. It did open the door for me to explain my ultimate goal of the simulation o...

Re: Anechoic sampled instruments and reverberation
Well, omni and cardioid electret elements are pretty cheap, and can be turned into very good microphones. In fact, I have a bunch of cardioid elements to turn into mics sitting right here. :) Combining these small microphones with "envelopes" of rockwool, following the "portable vocal booth" princip...

Re: A draft whitepaper of my parameterization idea
The only thing I can think of would be to build the non-linear part of the model as a piecewise-defined set of the solved linear equations. In other words, depending on the amplitude of the input sample, the appropriate linear model will be picked, process the sample, then output it. The feedback lo...

Re: A draft whitepaper of my parameterization idea
As you can probably guess by now, I care as much (if not, more) about the non-linear characteristics of the circuit than the linear. Simulating the linear properties is well-established and a lot of documentation exists on how to do it. Nailing the linear and non-linear at the same time, that's the ...

Re: A draft whitepaper of my parameterization idea
That's true for your basic diff-EQ based DSP filter, yes. In hardware, the filter cutoff (we're only using cutoff as an example, keep in mind) is controlled by changing a resistance value in the circuit network. This is the part I don't know, unfortunately: If you compile a circuit model to a set of...

Re: A draft whitepaper of my parameterization idea
This is where I show my fundamental lack of knowledge in how this level of math works. Does a Spice (actually, I'll say "Spice-like" for the purposes of this discussion) network need to be recompiled for any and every change made, or is it only if a routing or component type changes? If it's the lat...

Re: A draft whitepaper of my parameterization idea
Hrm, a Google search for "continuous integration environment" turns up a definition about a software engineering practice, with stuff like automated nightly builds, automated unit testing, and the like. I can kinda see how that might apply here, but I have a feeling when you say "continuous integrat...

Re: A draft whitepaper of my parameterization idea
Circuits it is! So, compile-time vs. runtime. Well, for making an instrument, we can certainly go for compile-time, but the ability to create sound designs (I hate the term patches here, because it's too easily confused with code patches) should be doable at runtime. So, thinking in Reaktor-like ter...

Re: A draft whitepaper of my parameterization idea
* Did you check out K-3D? We're using the Observer Pattern for almost all communication, in particular the Visualization Pipeline (the network that makes up a scene/document), implemented using sigc++ which is excellent for networks built at run-time. Take a look at libsigc++. I went to the K-3D si...
