Re: All Eurorack Chaos modules

Here's a chaos module that most may not recognize as such: the Pulp Logic V-Noise (video noise.) These types of noise generators use shift registers with feedback to create long, noncorrelated, but ultimately deterministic binary patterns that mimic randomness. That's chaos, pure and simple. The im...

Re: Cybernetics and AI with Serge

Interesting video (the first one, I'll catch up), particularly the part about the industrial use of AI as compared to the small scale artistic use of neurons. I'm not so familiar with serge systems, though the patch ideas should be transferable to other systems. i share her surprise at things like U...

Re: All Eurorack Chaos modules

I'm thinking about this recurring question, is Module X chaotic, since it has chaos in its name or description or just behaves in unpredictable, random ways? If the module has a circuit with known chaotic dynamics the answer is easy, same thing if it is known to be random rather than chaotic. But wh...

Re: An idea for a microtonal MIDI-keyboard

Looks like a promising idea. The organ players who performed on Harry Partch's Chromelodeon may have had difficulties at first finding their way on a keyboard where a sounding octave spans almost four octaves of keyes, but they apparenty got used to it. You have probably seen designs for 31TET keybo...

Re: two soundcloud albums

Brilliant baroque interpretations!
They also put the more modest chaos clips into perspective. I don't know if they are intended as module demos or studies, but hearing them in a collection it is striking how their musical syntax differs from that of any other music.

Re: Self generating patches....tips and ideas ?

Something-else. I tried to use my A-156 quantizer in a feedback loop. I did not work the way I hoped :-( Although I don't know what else was in that loop, let me guess what could have happened. For a feedback loop to start oscillating periodically or chaotically there must be a bit of amplification...

Re: Rojo - Prepared piano and modular

Is it some kind of trend to play piano with modular? Apparently it's a field worth exploring. As I listened to this it struck me that it might be interesting to use the piano's resonance for the modular sounds in order to blend the two. You could put small speakers inside the piano and keep the peda...

Re: Harmonic Series

I think doing it digitally is fairly straightforward since you can guarantee that everything remains in-phase (the hardest part actually being the sine calculations and not running out of compute cycles if it's running on a small chip). In practice you would have a wavetable for the sinus and one f...

Re: Harmonic Series

Yes, I'd think that for practical purposes sync as described would be fine and some drift should not matter much. However, restarting the waveform with sync will introduce a discontinuity so the sinus will have its own harmonic series which will be prominent if this occurs regularly and the step is ...

Re: Audio Analysis (Waveform to wavetable matching)

MIR is music information retrieval. They have their own conference with online proceedings.
This kind of thing would also be doable in mathlab, R, octave or whatever. And it might be a little easier than c++.

Re: Feedback

Nice song and interesting arrangement. I have trouble hearing the lyrics in some parts, maybe it's masked by the percussive sound. When you abandon the lofi mono sound for gestures in stereo you are somehow breaking an illusion. I'm fine with that in the first part, but I find the ending less convin...

Although this does not remind me of early musique concrète (it's cleaner and calmer) there is something familiar about the tracks where there are a few things going on simultaneously. Not sure what it is.

Re: Audio Analysis (Waveform to wavetable matching)

I'm not too well versed in current software, but I think the tasks you describe have been implemented in various ways. The problem of finding a match for a target sound in a large data base is at the base of concatenative synthesis. Diemo Schwartz and others have written papers about it and I think ...

Crowds are often wrong. It is perhaps a pity that the movie doesn't exist, because it would deserve a soundtrack like this one. Not much to add, except that the snare sounds a bit mp3-compressed or something. Towards the end it might be a good idea to clear up the backing guitars or other instrument...

Re: What harmonics do wavefolders add?

but just to clarify the main thing i was interested in was a more mathematical description of what harmonics are added. It may be easiest to think about this if the input is a sinusoid. Then the wavefolder has a transfer function f(x), and the output is f(A sin(t)) where A is the amplitude. If f() ...

Are there any modules that can calculate rate of change out-of-the-box? Seems like it would be a common function, but i don't know how to write a program that does calculus. Rate of change or a differentiator would actually be a highpass filter with a linear frequency response all the way. But imag...

Re: Why do FM patches so often sound like bells (NOOB ALERT!)

I just discovered a phase modulation version of exponential FM which it is quite different. Its partials don't shift with the modulation index. But I'm not aware of any implementations of it, nor have I seen it mentioned anywhere.

You can read about it here on the bottom of the page.

The one who has dug deep into pulsar synthesis is obviously Curtis Roads, who seems to be responsible for coining the term. It's described in his book Microsound.
