That seems cool to me,
but I remember writing to this list & [DigitalHell] recently,
asking how to do this with a "touchpad" to control MIDI data,
any DIY ideas been tried ?
Im mainly guessing its finding the right software to work via the mouse
& or joystick ports of a PC.

Also, modding a Peavey PC1600 to use this type of controller ?
what would it take to intergrate the XY(Z?) of a touchpad into its faders?

Thanks
