[sdiy] Silly vector synth question

[Gordon JC Pearce]

How does the control law for a vector synth joystick work?

If I have the classic "diamond-shape" joystick with an oscillator at
each point of the compass, then with the stick centred I should hear all
four oscillators equally, right?

So if I then move the stick north, south will fade out and north will
become louder - but with the stick fully north won't I still hear a
50/50 mix of east and west?  Does that get "buried" by the increase in
level of north?
