[PD] Re: Force Feedback Joysticks

[vanDongen-Gilcher]

Hi, 

This must be morphological resonance or something.


I just finished a small lib of force feedback externals for linux.
They are still a bit unstable, but so is the kernel api :)

I need to set up some web space for this. Next week I will have time.

Right now I am using them for a performance this wednesday in Rotterdam, 
Netherlands.
A complex patternsequencer type patch controlled by a midi faderbox and a 
ff-joystick that shakes and pushes with every drum hit.

Basically you can upload a number of effects to the device and then play /
change them.
The externals I have are: 
ff-constant, a constant force in a given direction and a duration. Nice for 
drum hits
ff-periodic, a shaking effect, different waveform, in different directions.
ff-spring, makes the stick behave as if there are springs in x and y 
directions. You can also set a center and a deadband.
Nice for controlling a filter with a specific resonant spot.

ff-friction, programmed but untested. 
and general ff-gain and ff-autocenter controls. 
It is a lot of fun.
      
You need to patch the kernel (although I think it is standard in the 2.5 
series now)
I needed to mess with the driver anyway because my "iforce compatible" 
joystick was not. At least for the linux iforce module.
It is all a bit tricky to set up.


Anyway I am swamped with work until after thursday. Then I will clean 
everything up and make them available.

regards

Gerard
