An abstraction : markov finite state machine
by Alexandre Quessy 17 Aug '06

17 Aug '06

Hi all, I just rewrote an abstraction for creating markov chains using a matrix storing the probabilties to get every other states in the finite state machine. Probabilities are caclulated on the sum of every float of every row. A row corresponds to a state (actually, its probabilities to obtain every state next). See wikipedia.org for mathematics behind it. It is available at http://alexandre.quessy.net/?q=node/43 only at the moment. This kind of system can be used for weighted random between several effects in an installation, or to build melodies of chord changes, for instance. It uses zexy and iemmatrix. Ah, it is GPL, let say. Cheers, -- Alexandre Quessy http://alexandre.quessy.net

deep notch filter
by Hans-Christoph Steiner 17 Aug '06

17 Aug '06

I want to build a very steep, narrow notch filter. Any suggestions as to how to do this? I've played with [notch] and [biquad~] but haven't seem to get the results I am looking for. .hc ------------------------------------------------------------------------ I spent 33 years and four months in active military service and during that period I spent most of my time as a high class muscle man for Big Business, for Wall Street and the bankers. - General Smedley Butler

Anyone has an algo somewhere that I can reuse ? I am thinking about music notation softwares. Maybe a free software like Rosegarden have this feature ? -- Alexandre Quessy http://alexandre.quessy.net

Waveform in GEM
by raul diaz 16 Aug '06

16 Aug '06

Hi list! I'm starting to learn GEM and I would like to make a patch which visualize the waveform of a dinamic input audio signal into the GEM window (something like an oscilloscope). Is there some abstraction which make this? Any suggestion about how to implement this? Thaks and best regards! Raul Diaz Poblete ************************* raul.lete(a)gmail.com Ciudad Real [Spain]

Audiotester
by João Miguel Pais 16 Aug '06

Hi, I've developed a patch to test a multichannel setup. Presently it is configured for my RME Hdsp card, with 8+8+2 channels. In case you might want to use this patch with another setup and can't wait, let me know. It should be no problem to make a custom version of it.

Iterative text with Gem?
by David Plans Casal 16 Aug '06

16 Aug '06

Hello all, I've just been given a project where I have to display iterative zeros (and after the other, every second) on a screen unless something happens, in which case I need to display a 1 and stop. I can display text using Gem's [text3d] object, but although the example patch displays one bit of text at a time, it seems the object won't append text. Am I wrong? Can anyone think of another, easy way to iterate and append text on a Gem screen, or otherwise? David
