A collection of effect tutorials in many languages... :-)
Congo v6 has 4 effect types: Chase, Dynamic, Content and Image. This tutorial covers the Chase Effect.
In this short tutorial, I'll walk you through the
creation of a simple intensity chase effect object and then through
using the new Chase Effect Playback to get that chase running on stage.
You can use any play file to start with this tutorial, though I am
assuming that there are no Effect Playbacks already inserted into that
play. If there are, please choose a new number to use for the Effect
Playback in step 2.
Playbacks are used to play back "Chase" objects. Each Chase Effect
Playback has two parameters - intensity and "Chase". Intensity acts as a
master over the high levels output by the running chase - if you bring
the Chase Effect Playback up to a level of 50%, then the chase will be
limited to a highest level of 50%. If you take the Playback to 100%
(Full), then the chase will play back with the levels you recorded into
it.When the Chase Effect Playback is above 0% intensity, the chase can
be said to be "running". When the Chase Effect Playback is brought back
to 0%, the chase can be said to be "stopped".
Playbacks exist to play back Chase objects. The Chase object contains
the channels and the steps and the timings you want to use in your
chase. You can create a Chase Effect Playback and Chase object
simultaneously from Live, or you can create Chase objects in a list and
then play them back later. The default behavior of a chase is to go from
0% to 100% intensity on selected channels in a time of 0.2 seconds per
step. You can edit these defaults to create customized chases of your
Create a simple chase effect:
1) Select channels 1-10.
2) Type  [INSERT]&[EFFECT] (press and hold the [INSERT] key
then press the [EFFECT] key, then release both keys) - this will open a
dialog box that you can use to set the Effect Playback type.
3) In the first tab, Chase Effect, select the "Use selected
channels" box, enter 10 in the number of parts, and leave the
distribution as Sequential. Select EXECUTE and press [MODIFY] to insert
the chase playback and also make a new chase object at the same time.
The effect playback is selected after you insert it so all you have to
do to get the effect running is bring the level wheel up above 0%.
4) Press [SETUP]&[BROWSER] to open the Dock setup dialog. Docks
are special display areas you can add to any screen connected to the
Congo, the Browser is a Dock area that we open by default. In the
"Bottom Area", open the drop-down menu and select "Effects", then select
the MODIFY button and press MODIFY to close the dialog and open the new
Effects Dock. In this dock you can see the inserted Effect Playbacks.
5) In the Browser, under Effects, you have all the effect
data types. One of those is Chase Effects, and under that node you'll
Chases (chase objects). The new chase that was created when we inserted
playback is in that list. Press [MODIFY] on the Chases node to open the
chase object list. Press [INSERT] while focused on this list view to
insert a new chase object in the list. The Channel Distribution Wizard
will open and you can use this wizard to insert your channels and steps.
Select channels 11-20, then enter the number of steps, in this case 5,
then choose the distribution method "Symmetrical" and select the EXECUTE
button and press [MODIFY]. This inserts a new chase object using those
channels distributed symmetrically across 5 steps. Add a text label to
the two chase objects you have in the list - name the first one "Bob"
and the second one "Joe".
6) Now that you have more than
one chase object, you can play with the setting of the Effect Playback
 [EFFECT] to reselect the Chase Effect Playback you inserted before,
then look at
the encoders. The left-most encoder should display the Chase parameter,
you can use the wheel to select which chase the playback is running.
Bring up the intensity of this Chase Effect Playback using the level
wheel (you can also use keypad commands to set the intensity, just as
you would for any other channel). Since we have not yet chosen to run a
different chase object, Effect 1 should be using the chase called Bob.
When you bring up the intensity of Effect 1 you should see channels 1-10
chasing one by one. Use the encoder to dial up chase "Joe". You should
see the chase on channels 1-10 disappear and now channels 11-20 should
be chasing two at a time. If you move the Chase encoder back and forth,
you can see the different chase objects switch as you move the encoder.
Chase Effect Playbacks can only play back one chase at a time.
If you want to be able to play back both the Bob and Joe chases at the
same time, you need to insert another Chase Effect Playback. This is
easy to do live, using [#] [INSERT]&[EFFECT] again (you can use this
dialog to insert yet another new chase object at the same time, or you
can simply execute the insertion without also making a new chase object -
your choice), or you can open the Effect Playbacks List in the Browser
and use [INSERT] to insert a new playback into the list. Use [#]
[EFFECT] to select the new playback and use the encoder to set it to
play back the other chase, then bring up the intensity. Now you have
both chases Bob and Joe running simultaneously.
7) To edit the
contents of a Chase object, you can use the Browser or the new Effect
soft keys to open the Chases list. To use the soft keys, press the
Effect softkey to enter the page of effect commands, then press the
Chase soft key to open the Chases list. In this list you can see the
top-level settings for a chase. Direction and Style settings can be used
to change the order of the steps and how the output of those steps gets
played back. The Loop Time can be used to adjust all the step times in
the chase to complete a single pass through all the steps in the total
time entered in the Loop Time cell (so, if you have a 5 step chase for
example, and you want it to take 10 seconds to make it through all 5
steps, enter the value "10" in the Loop Time cell. Congo will edit the
step times on those 5 steps to 2 seconds, causing it to take 10 seconds
to get through all 5 steps.) In, Dwell and Out time cells are available
at the top level to adjust all steps to use the same timing quickly. Min
and Max Rate settings can be used to speed up or slow down a chase
evenly (set both Min and Max to the same value) or unevenly (set Min and
Max to two different levels). When using the uneven settings, the Chase
will randomly set the rate per step to a value between the minimum and
maximum rates. You can use this to create organic chases for water,
fire, tv, or any other irregular intensity effect you would like to
create. Set these values close together for subtlety, or far apart for
really erratic chases.
If you want to edit a chase step-by-step,
select the Steps cell in this list and press [MODIFY]. This opens up the
step editor where you can add or delete channels from individual steps,
adjust the step and fade (In/Dwell/Out) timing for each step, and
adjust the high and low intensity levels for each step. Standard table
editing rules apply in this view, except for adding/deleting channels in
each step. To adjust the channel assignments, simply select the step
you wish to edit and look up at the top half of the tab. The channels in
that step are selected (shown with the gold rim) like they are in Live.
Use regular channel commands to adjust the channels assigned to this
step: to add a new channel and keep the old ones, simply type [#] [+];
to remove a channel from this step, type [#] [-]; to completely change
the channels assigned to this step type [#] [Ch] and continue adding
channels normally. For those who use At Mode, normal channel selection
syntax works here as well.
I hope this helps you to get
comfortable with the new Congo v5 Chase Effects.
