Using a mouse for all this really isn't good enough for serious work. Hardware 
knobs, sliders, push buttons, drum pads and MIDI keyboards are all fairly 
standard kit these days. These ideally would be dealt with on an OS level 
rather than having different implementations for every application. This 
surely is the Linux way of doing things?

Oh good, I'm glad someone has mentioned Ardour in this conversation, and what 
about the way Hydrogen does it? One is GTK and the other QT based. 
Standardise this approach for all apps and provide a straightforward way of 
mapping controllers to hardware sliders/keys. Surely this is the way to go.

Eye candy MUST be functional (otherwise it causes truth decay ;) The last 
thing I'd want to see is a whole load of varied interfaces where the visual 
impression overrides the functionality.
