Using a touchpad for custom things

[nitro2k01]

(Ok, this not specifically a Thinkpad question, but I hope it's allowed anyway)

I'm looking for a way to use the XY pad on my laptop for custom things. I already have a stick mouse (Like the ones usually present on Thinkpads) I'm a computer musician, and I'd ultimately like to use the touchpad as an X-Y midi pad. If anyone knows how to that specifically, it would be gold. Otherwise, just reading out the values from the API would suffice, the I could write my own application.

I've found Touchpad 2 MIDI, but unfortunately it doesn't work my ALPS touchpad. (They explicitly say that model is not supported.)

The OS is Windows Xp. Any help would be appreciated.

i'd also be interested in something like this...

it is going to do a lot with the controller for the mouse. Depending on who made it and how it works in relation with the system, it may simply be possible. I think such a thing is possible with the ultranav since it can be completely controlled by software alone (disable it, change the scroll regions, etc.) Can you specify what the computer you are trying to do this with? I may see if I can dig up some information.

The computer is a Dell Latitude D600.
Since that post, I've done some thinking. As you (Stargate199) say, the thing can be contrlled solely by software, so it shouldn't be impossible to do. I also did some research on the files included with the driver package, and it seems that the file vxdif.dll has some interesting entry points when I disassembled it. However, it will take some time to reverse engineer it properly, and I haven't really tried yet.
Please keep me posted if you find any info.

Yeah, the trackpad can be controlled by software, so it may be possible. I think what it comes down to is the driver files. It could be because of how the driver is programed, it is very hard to figure out the xy position of where there is movement by third part programs. Look around on some other forums and see if anyone has been able to do what you are proposing.
