A PatchCord amount of
50% is enough to drive Beat
Busy to the maximum setting.

Hot Tip!
The Bidirectional Mod Wheel:
Set Mod Wheel to BtsBusy with a
Cord amount of +100, then add
a DC bias to BtsBusy with a Cord
amount of -50. Wheel now adds
or subtracts "Busyness".

Cool Tip! Connecting
Key Pressure to Beat Busy at
50% increases BEAT complexity
the harder you press.

Suppose the pitch wheel (which can output both positive and negative values)
were connected to Beat Busy and four Key Triggers are down. As the pitch
wheel is moved from center to fully up, the remaining parts will be enabled
until the pitch wheel is fully up and all parts are playing. Moving the pitch
wheel from center to fully down, the four triggered parts are sequentially
removed until at the most negative position of the wheel, no parts are
playing.
The Busy control acts on the Beats condition whenever the control is
changed. Playing more triggers without changing the Busy control simply
adds them until the Busy control is changed again, at which point it will
possibly add or subtract parts as needed.
The interaction between the Busy control, Triggers, Part Velocity and Group
Velocity can get complicated, but works according to this rule:
WHICHEVER CONTROL WAS LAST CHANGED TAKES OVER
When interacting with the Group Velocity scale control, the Busy control
ignores group velocity even when it is set to zero, enabling and disabling
parts as necessary. If the Group Velocity is changed after the Busy control, it
takes control, scaling parts as it deems necessary.
The Busy control does take the Part velocity into account when adding and
subtracting parts. If a part has a velocity of 0%, it is removed from the list of
parts that the Busy control adds or subtracts. Therefore, you can use the
Part Velocity control to remove parts you don't want to hear.
Played
Positive controller values bring in new Parts and negative controller values remove
Parts that are latched or held. In this example, the Pitch Wheel is connected to
Beat Busy since it outputs negative as well as positive values.
Beat Variation (BtsVari)
Beat Variation varies which Parts are brought in and out using the Beat
Busy control. Increasing this control mixes up the order in which Parts are
brought in and out, thus providing even more permutations to the Beat.
