I just put up an update for my force feedback external lib.
changes:
It now has better error checking.
The library checks for available ff devices on loading, and assigns numbers to them as it finds them. (starting at 0) The externals now refer to the device by this number. (usually 0 if you have only one ff device)
If you run out of memory on the force-feedback device, you now can load and unload effects.
Ijust thought of another use for ff-effects: attach 2 ff joy sticks to the computer and make a copy of pd_joystick that uses the second joystick. You now can make forcefeedback music games for multiple players. Where your actions with your 'stick pushes the 'stick of your opponent. All in pd.

PS Hans-Cristoph, I have somehow lost your examples. Could you mail them to me again, and I will include them.
