Hi Maurizio,
I am using pd for live improvisations and for quick prototyping of sound effect programming. For the performances I use 2 main patches. One is a recursive pattern sequencer. It can run and loop a pattern, but every step can trigger an time scaled instance of that pattern. Up to 2 levels deep. I tried with more recursions, but that didn't give a useful result with the processor power I have available. It could be a way to make granular textures though. The patch has 4 pattern sequencers running independently. The sounds are made with csound~ objects, which also does the scheduling of the recursions. (I am just giving it score lines)
Control is done with a doepfer midifader box, the regelwerk (which also as a buildin patternsequencer, and is what got me started using patterns). And with a forcefeedback joystick. The forcefeedback is used to shake the stick for every sound/event in the primary pattern. The trigger is used to play/ add notes to the pattern. Topbuttons select which of the 4 patterns to work in, the hat is sed to delete events. The x and y and z (twist) axis of the joystick cntrol the sound. I am continously tweaking this patch and the csound orcs and scores. After every performace I change it a little bit. But it is slowly getting to be a "real" instrument. I still want to add a kind of variable resistance using force feedback to the joystick, to create zones or ridges in the physical response. (Actually I would like to work with a 6 degree of freedom haptic interface, but those are very expensive, they are used for remote surgery and NASA) Output is to my mixer with has nice parametric eq and then back to some effects in the pd patch. (tempo based delay, shifts, fm distortion) The music is some kind of abstract techno? I think it has a beat, but most people can't/won't dance to it.
The other patch I use, is for combination with accoustic piano. I have just started it. It used artificial neural nets to seperate the input and send it to various long (1 minute+) delay lines. Eventually it is supposed to work with multiple inputs so I can use it as an music controlled effect device for enseble improvisations. I wanted to get away from having to use controls at the same time as playing an accoustc instrument. I have done things usng analog gates and effect processors for esemble, where th playing triggers effects on the _other_musicians, and you have no control over the electronics on your own instrument. Although I might use the joystick in this context. A racing wheel attached to the piano will look better, almost bought one, but not enough controls. The music is "free" electro accoustic music. (I am practicing a score I wrote right now, so it is not free all the time)
regards Gerard

Hello.
snip
For example: is there people using graphic tablet or working with musicians which uses graphic tables as control devices? Do you/they use them =C3=A0 la caospad? Use more sophisticated controls? Are someone developed more evolved widgets than [grid]?
What kind of music can you make with that? This is also very important. Not the "genre" per se but the kind of musical operations you do.
Thanks for your patience. Your answers will be very appreciated.
I would also like to share development efforts and ideas with other developers or musicians with programming abilities if there is some agreements on the result to achieve as I still believe in open source.
