After a redesign and a little bit of "face lifting", KEnvy24 is now more compliant with KDE4. It's being built using KParts and the most important one, the Mixer Part, is now working OK. Just take a look into the KDE4 playground/multimedia. Also, take a look to the screen shots.
The other parts to be completed are the "Surround Part" (though, I have no surround system) and the "Configuration Part".
I done the development using mainly a DMX 6Fire I received from Vedran.
Please let me know if you need a source release here.
