I worked in a start sound for KDE, and I have a preliminar version here.

http://ompldr.org/vaWQ2dw/Oxygen%202%20-%20Start%20session.ogg

I tried to keep it close to Oxygen, while introducing motion patterns and making the melody line more complex, to show progress. KDE has made an enormous progress between 4.0 and 4.10, and we must show that progress through our sound theme, too.

Of course, since this is a FOSS project, I'll publish my sources in open formats (in this case, a MIDI file) on request, and the definite license of this will depend on KDE's needs. Since I'm the sole author of this, I can relicense this in any way I want.

Please, comment.

Gear: Korg M50 sequencer and FX units; Ardour for the final mix.
