My main PC keyboard is a PS/2 so I had three plugged in at a time. It will also work with Bluetooth keyboards... for example a Wii controller. Anything that generate an event* file that looks like a keyboard. It does take a little bit of looking to find out which /dev/input/event* file to use as device. I have found using the /dev/input/by-id/* files is more specific... the by-path may be better. I have not touched tha code since I got it working as it is pretty basic and just works. The worst part is dealing with what is normally a root owned device from userland because jack is userland. Basically, Create an input group, add yourself to it, drop the supplied file into whatever directory your distro merges udev commands. And the input devices will be owned by the input group. At the time I did this, I had just started coding again and the Jackd API was much easier to understand. I would be better in the long run to make the output/input an ALSA MIDI device. (safer) Though it seems there is a way to monitor key strokes that the xserver is seeing too. Be careful in other words. -- Len Ovens www.ovenwerks.net
