So, after asking here about MIDI controllers for touchpads a while back I
went ahead and made something out of my vision of how it could work. It's
a pretty primitive command line X11 program sending ALSA MIDI. X, Y and
Z axes can be mapped to controllers or pitch bend and 2-fingered touch
can also be used as an on/off switch for hold pedal, portamento or
whatever.
For now there is only source to download, but as there aren't very many
dependencies it shouldn't be much of a hurdle to compile and run. Bug
reports and improvements are welcome.
You'll need a touchpad that works with the Synaptics driver in X to use
this, but beware that any driver version and hardware compatibility is
quite untested, except for Ubuntu Karmic on Eeepc 901.

Great idea! I wanted to make something like that for a long time now
but wish was never strong enough and there were always some 'more
important' things :)
But I couldn't get it to work... :(
I first tried on my main computer (dell XPS m1530) with Arch on it.
Configure script wasn't working. It reports [1]. But inspite of that
make went through without problems. SHM is enabled in HAL (at least I
think - 'synclient -m 100' works). But when I try to run it it reports
[2]. But there is Alps touchpad in it (it is using synaptics driver
but it is not made by Synaptics) and maybe that is the reason.
Then I tried on Asus Eee 701 with Jolicloud (Ubuntu variant) on it.
This time configure script worked, 'synclient -m 100' worked too, but
again when I try to run it (./midipoke -x 1 -a), I get the same error
[2].
Regards!

If 'synclient -m 100' reports some numbers there is hope, no matter what
the actual hardware is, Alps or Synaptics or Acme or whatever.
[1] That script only checks for the required headers, it's only a helper
and not a configure script per se. Some day I'll get around to navigating
the autoconf jungle, but for now this is what I have.
The bug seems to come from some versions of bash accepting comments
inside a $(...) statement and some don't. This will improve in the next
version. (I think there even are some people with sh!=bash)
[2] Could this be about root privileges, what does 'ls -l $(which
synclient)' tell you? You could try 'sudo ./midipoke -x 1 -a' as well.
