Hi Martin,

Do it. It would be great.

Don't forget to crosslink with the tutorials Paul Davis and Dr. Matthias
Nagorni have written.

This would probably be a bit beyond. Maybe evaluation about how suited they
are would be good. You know, whter they have (custom) controls which audio-apps
usually need (like vector-curve, range-contol, popup-sliders, waveform-display).
