What I would really love to do is be able to control the forces and
vibrations directly from PD, rather than having to load pre-built
'effects'. From what I've read, it might be possible to emulate this
by dynamically switching effects, but that seems like a bit of a pain
to code. I just found the linux FF API and have only started looking
into it. Is there any way to directly control the forces and
vibrations?
I look forward to getting your code. I have also been trying to think
of a way to incorporate FF into jsarlo's joystick object, but I haven't
figured that one out yet.
