hm guess at this point you might have to provide some more infos about the pd/gem-version you're using & the output of your startup, which patch makes it crash & the output when gem actually crashes. & please cc to the list as there is more gem knowledge around!

Re: [PD] Finding "$0" and dealing with it in messages

Well I don't know about implementation, but conceptually, I don't see $0 (in object boxes) as something that much different than $1..$n: you can think of $0 as just one more creation argument of the containing patch (a numeric value), only that it is assigned automatically and guaranteed to be unique. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

[++ ] object wont work
by Konstantinos Benardis 13 Nov '09

13 Nov '09

Hi list I want to trigger a bang when a specific number occurs in a serie of running numbers for example from the output of a line object. I use the [== ] object to lookup but the object wont work if the numbers are running too fast. What could be the problem? Is there another way to do the lookup? Thank you

copying one array to another very fast
by Hans-Christoph Steiner 13 Nov '09

13 Nov '09

I want to copy the contents of one array to another as fast as possible. Basically, I'll load a sound file into an array, and fill a big buffer by concating that soundfile to the big buffer until its full. Any ideas? .hc ---------------------------------------------------------------------------- If you are not part of the solution, you are part of the problem.

arduino problem with analog sensors
by altern 12 Nov '09

12 Nov '09

hi not a PD question I guess... i dont know much of electrical stuff. i am connecting two analog sensors to the arduino. One is a pressure sensor and the second a potentiometer, they are both from an old icube. i noticed that when i raise the potentiometer (analog pin 5) the pressure sensor (analog pin 2) reports values ranging 0 to ~0.16 increasing together as the potenciometer goes up. It is like some kind of residual noise comming from pin 5 that goes into pin 0. the power cables of both sensors go together to 5v inlet of the arduino and the ground cables go to ground pin, each of the data cable goes to its separate analog pin. I am using arduino from Pure Data extended using latest Firmata, so i am just filtering out any value smaller than 0.16 coming from analog pin 0. is there anything I am doing wrong? or is this normal? thanks enrike

midi novice
by Green 12 Nov '09

12 Nov '09

hallo never used midi before and i'm trying to figure out how to control a mab-303 synth from pd. i'm stuck cause the synth manual says the slide function is controled/triggered by sending a "controller #64" or "controller #65" message to the machine. any of you know what that is, and how to do it from pd? i'm sure this is very obvious but the manual is very cryptic. peace

Safe video feedback in Gem?
by Dudley Brooks 12 Nov '09

12 Nov '09

I want to feed an output image (modified) back as input to itself, to create fractals. Could someone point me to an example of doing so? So far, googling has only produced articles on *avoiding* feedback, and in audio at that. Thanks.
