Changing speed and crossfade
You can always change the speed of the chase using the Speed slider and the
Crossfade time of the chase (time to crossfade between steps) using the Value
slider. A crossfade of 0% gives instant switching between steps, a crossfade of 100%
gives constant movement.
Chase A and Chase B have independent speed and crossfade times; if you’ve currently
got Chase A selected, then the changes will be applied to chase A, and similarly for
Chase B. If the current value is different to the position of the slider, you will need to
match the slider to the current setting before anything will change. The display will
show
Current speed: 54%
Move slider to match
This avoids the problem of the speed or crossfade ‘jumping’ to the current position of
the slider.
In Sound mode, the Speed slider sets the ‘pace’ of the chase, but the actual speed is
also set by the music. The controller will run the chase for a few moments after each
beat in the music; at fast speed settings you will get a ‘burst’ of steps, and at slow
speed settings you will get only one step. The light above the Sound button will blink
when a beat is detected. The Value slider still sets the time to crossfade between
steps. You can go back to automatic (No Sound) mode by pressing Sound again to
turn the Sound light off.
Note: You will only see the ‘burst’ effect at fast chase speeds; fast chases are
most effective on shutter open/close (strobe) effects, as the head may
not be able to respond fast enough to other movements.
Chase Link mode
If you run two chases together, the controller will remember that you have linked the
two chases. When you recall one of the chases as Chase A, you can tell the controller
to automatically recall the other one as Chase B. This is to allow you to select
combinations of chases with just one button press. You select this option using Chase
Setup option 5 (see next section). You can also tell the controller to replace any
channels in the chase that are set at zero with automatic light show information.
If you stop Chase A (by pressing Cancel), Chase B will stop too if it was
automatically recalled as a linked chase.
