Dimension coupling<br />
“To draw freehand, one prefers a mouse; to draw straight vertical<br />
and horizontal lines, the humble Etch-a-Sketch is better” (Buxton<br />
1986).<br />
The simultaneous manipulation of the resonance frequency and the<br />
Q factor of a filter, is perfectly controlled with a two-dimensional<br />
joystick.<br />
NB. We are here considering input coupling, not output correlation<br />
which we will discuss later. However, it seems that output<br />
correlation in trad. Instruments is one of the keys for<br />
“expressivity” (e.g. loudness & pitch in wind instruments, voice…)<br />
