As a rule of thumb, if the parameters are related to each other (i.e. channel level controls) then it is clearer to use sliders because the user can compare the relative levels. If the faders are NOT correlated, then I find it misleading to have them arrayed next to each other. Knobs work pretty well in the "uncorrelated" case because your eye doesn't even try to decipher the relative values. My biggest beef with knobs is the variety of ways the mouse movement is implemented. Most software gives you no clue ... vertically? horizontally? radially? ... and Murphy's law says your first 2 guesses will be wrong. The app "Soundplay" for BeOS takes a novel approach ... the level is shown as a knob but when you grab it, a rectangular box appears behind the knob and you adust it like a fader. This is great because it gives you visual feedback of which direction(s) to move the knob. -Ben Loftis
