Wow Jean-Marie - amazing story! I'm glad to know it, though it's unfortunately quite familiar sounding.
Implementing your work as pd abstractions is a fantastic goal! It would be amazing to work with you on this. It's worth mentioning another commercially successful - but actually completely open source modal synthesis project: https://mutable-instruments.net/modules/elements/ and while it doesn't sound like you're excited to read code these days - all of the dsp for that module is here: https://github.com/pichenettes/eurorack/tree/master/elements I'd be curious to learn how similar that might be to your work. At any rate - I'm going to start digging into this! -jesse > On Aug 6, 2017, at 12:58 PM, Jean-Marie Adrien <jm.adrien....@gmail.com> > wrote: > > would be great if it would be in pd abstractions ! > everything is in the paper though, you are right, and the method is > incredibly powerful, so the project was in that time to control it with > gestures data bases and artificial intelligence and so on, all of this being > existing now, not speaking about multi channel sound diffusion etc. > I was disappointed when, after having developed the method at IRCAM, i > discovered (and had to pay for it though) some ten years ago the actual > modalys thing that was kind of retro engineered after i left IRCAM, from the > big C++ initial software with was developed between 1984 and 89. > > The math is not so complex, it is just a matrix equation incremented step by > step, and very straightforward and intuitive discontinuities in time domain > which correspond to straightforward updates of the matrix, resulting for > instance from contact between objects and other intuitive events. > If you simplify the maths, it will probably become more complex i’d say, and > you will probably hear it, because time domain sound synthesis is quite > sensitive. > > On the same line, one advantage of modal synthesis is that you can achieve > impossible physical excitations on imaginary structures, and interpolate > between all this, having transient sounds and articulations, but even with > the full math though, you could hear in that case that you were sort of > tearing the equations, which corresponds to the fact that there is no > existing physical gesture which you could refer to when exploring impossible > configurations. > Math simplification is what happened probably when the available pd modalys > software was achieved : i was disappointed by this tool and rarely use it. > Another application has been developed by Apple in Logic with the "sculpture > » plugin : it is very much main stream, they probably make money with it and > Im still poor.
