With the linux miditouch application, you can use your graphic tablet as an instrument. It converts touch events (from the X11 server) into midi events.
It is a very simple application.
Configuration of the device
Warning : you have to correctly configure your tablet (as a floating device and in the "absolute" mode)
You need to follow the procedure to install the tablet (please read these instruction on the linuxwacom project web site). You will need the "xinput" and "xsetwacom" tools to configure the device as follow.
Commands :
First get the XID number of your device
xinput --list
Then set the floating mode for it. If for instance the xid is 21
xinput --float 21
And finally --set your device in the "absolute" mode
xsetwacom set 21 mode absolute
Compilation
The application was developed with the Qt-Creator development environment.
You need to install qmake and the required libraries.
Then :
qmake
make
sudo make install
