Hi Simon,
I have an (unpublished) program for converting joystick input to MIDI output
which could help if you're thinking along Steve/Will's lines. I could also
help convert joystick/keyboard/mouse to joystick/keyboard/mouse/MIDI if that
is what you need.
However, I understood that you want to generate switch presses
programmatically rather than based on direct user input (perhaps for testing
other switched devices? Could do some interesting automated research...).
There is a computer-controlled relay array that we have used before.
Essentially, this is a bank of switches that can be turned on or off
programmatically.
I can't remember the specifics at the moment, but I think we get them from
Germany and they aren't (too) pricey. There are 4 (or maybe 8) relays that
can be controlled independently. As I recall, the response time is quite
good.
You can control it from The Grid 2* or I'm sure we could rig it up to work
with input from keyboard, mouse, joystick, GUI, other software, etc if
required.
Let me know if you are interested and I'll dig out more info.
All the best,
Barney

Hmm, OK, well if you 2 haven't a handy solution, Steve and Will, I'm
guessing there isn't one, so I'll dig! Thanks for the help, I'll explain
why if it works!
Cheers.

I reckon what your trying to do Simon is not very standard..(!)
This may be going a bit off the topic.. but bear with me..
The closest I can think Simon to what *may* be useful is mapping the
joybutton using standard bits of software and then reading that conversion
(e.g a key stroke). To do more interesting things than mapping joybuttons to
other things I have in the past used OSC (Open Sound Control) and/or
GlovePIE on windows to map the Joy buttons to something more meaningful i.e.
port it out to a serial command). (NB:
I did my OSC stuff using OSCulator on the mac. OSC if your not aware is
awesome).. Dare say though that is not the answer you are looking for.. (!)
