General Description
To record a Chase, press;
[RECORD] (CHASE)
The Record Chase key flashes and the display asks “Chase no” (Chase number).
Page Selection
Chases can be recorded in any submaster in any of the 9 pages of memory. Repeated presses of the PAGE
key will cycle through the 9 pages of memory.
To switch
directly
to a page;
Press and hold [PAGE], Tap [S/A] (Page number).
As you select each page, all Submasters will flash twice, indicating that they are a valid choice, then
Submasters containing chases will
flash
quickly
. (Submasters containing scenes remain lit and
empty sub masters are not lit.) This acts as a warning to you of existing chase (and scene) numbers
and unused numbers in each page.
After choosing a Page number give the chase a number by pressing;
[S/A] (Chase number), (any Red preset S/A key) or press
[S/A] (Grab), to record the chase on the Grab master.
Note; Recording over an existing chase or scene number will erase the previous contents.
The display will briefly display the Page/Chase number (or “Grb” if the chase is recorded on the Grab master)
and it will then scroll “Add steps”. The [RECORD] (ADD STEP) and the [FUNCTION] keys flash.
Recording (Adding) Steps
Each step of a Chase consists of a snapshot of the output which is taken when that step is “added”. Hence
the steps that you add may consist of single or multiple channels or scenes.
Create the first look on the output, then, to record it as the first step, press;
[RECORD], (ADD STEP)
Create the next look on the output.
To record this step, press;
[RECORD], (ADD STEP)
Continue to create and record steps as above. The display shows the latest step number.
If the look that you add is not correct, the last step may be deleted by pressing;
[RECORD], (DELETE STEP)
HINT: If a step other than the last step is incorrect, complete the recording then Preview/Edit the
chase. With Preview/Edit, any step may be deleted.
Chase Rate
Repeated presses of the [FUNCTION] key will toggle the display between the STEP number, the RATE
setting in BPM (Beats Per Minute) and the IN & OUT fade percentage. When the RATE is displayed, the Edit
wheel may be used to set the desired rate. The default setting is 230 BPM.
Bass Step
Chase stepping may be synchronised to the bass beat of an audio input signal (Sound To Light).
Whilst setting the chase RATE (above), setting the rate below 0 BPM will change the chase stepping to
“BASS STEP”. The Bass Step audio level may also be adjusted so that the chase steps on the correct beat.
See “CONTROLLING A CHASE”, “BASS STEP” and “BASS LEVEL”, later in this chapter for details.
Chase Fade
Traditionally, chases will snap (instantly switch) from step to step but in the Atom you may also elect to record
a FADE time for the chase so that the chase will crossfade from step to step.
The fade is recorded as a percentage of the chase rate.
Repeated presses of the [FUNCTION] key will toggle the display between the STEP number, the RATE
setting in BPM (Beats Per Minute) and the IN & OUT fade percentage. When the IN & OUT indicators are lit,
the Edit wheel may be used to set the percentage of the chase rate that is used for the crossfade. The default
setting is 0%, ie. No fade.
See “CONTROLLING A CHASE”, “FADE”, later in this chapter for more details.
Completing The Chase
When all steps have been recorded, complete the chase by pressing;
[RECORD], (END CHASE) The display briefly displays the recorded Page/Chase number.
The chase will be a conventional forward running chase. To select other chase modes, Preview/Edit the
chase as described below.
