Normally, when the key is released, the mix point moves from 3 to 4 at rate
4, unless the alternate release footswitch is held, in which case it moves
from point 3 to point 4 at rate 4A. In either case, to retain a desired feature of
traditional instruments, this nal release vector is not linear, but exponential.
This just means that the point moves quickly at rst, then gradually slows
down.
Effects of Mix Joystick
The x and y coordinates of the mixer envelope can be modulated by several
sources, such as velocity or either LFO, creating subtle timbral changes as
the oscillator blend changes. If you want to accent specic notes with further
timbral shifts, the Mix joystick can also temporarily modify the oscillator
blend without overriding the mixer envelope, making it a unique performance
controller.
Unlike the Pitch wheel (which aects the pitch of all oscillators based on its
current position), the joystick aects the blend of each note based on how far,
and in which direction it is moved during each note. That is, if the joystick is
moved all the way from A to C while a note is held, the amount of oscillator C
increases for that note. If the joystick then remains stationary, and another key
is played, it plays with an unmodied mixer envelope. All joystick movement
relative to its initial position when a note is played determines the shift in x and
y coordinates.
Figure 8-2 demonstrates the eect of moving the joystick b) from its initial
position to C between mixer envelope points 1 and 2: and c) from C to B
between envelope points 2 and 3.
