Fixture Tutorial
Until version 1.0 Lassi did not include any specific support for moving lights or intelligent fixtures. Starting with version 1.1 some basic building blocks for fixture support start to appear in the tryout area. This functionality is far from complete, but is already released for you to try out.
This tutorial walks you briefly through the functionality that is already available today.
Add fixtures to show
First we will add some fixtures to our show. Select Windows > Tryout > Show Fixtures to open the Show Fixtures window. Select the fixture type from the tree in the upper left corner. For example click on "Favorites" to open the Favorites category, and within this category click on "MAC250 m4" to select this fixture type.
Now type 4 in the "Number of fixtures to add" and click the "Add" button to add 4 fixtures to our show. Note how default start addresses have been assigned to the fixtures. These addresses can be changed in the table on the right.
Open virtual midi control surface
At this moment the fixtures can only be controlled from a midi control surface. If you do not own a midi control surface, you can open a virtual midi control surface (BCF2000) by selecting the menu option Windows > Tryout > BCF2000.
Select fixtures
To be able to select fixtures that we will control from the midi control surface, we need to bring up the Fixture List window: Windows > Tryout > Fixture List.
Select one or more fixtures from this list, and move the faders on the midi control surface. The faders are assigned to the fixture attributes as shown in the overview below. Currently this fader to attribute mapping is fixed in the program; the idea is that this becomes user configurable in a later release.
| Intensity | Fader 1 |
| Pan | Fader 2 |
| Tilt | Fader 3 |
| Zoom | Fader 4 |
| Iris | Fader 5 |
| Focus | Fader 6 |
| Shutter | Fader 7 |
| Color | Fader 8 |
| Speed | Encoder 1 |
| Pan Fine | Encoder 2 |
| Tilt Fine | Encoder 3 |
| Gobo | Encoder 4 |
| Gobo Rot | Encoder 5 |
| Gobo Pos | Encoder 6 |
| Gobo2 | Encoder 7 |
Set fixture color
To change to color of fixtures that support CMY or RGB attributes, you select Windows > Tryout > Color Wheel and Windows > Tryout > Color List to open the Color Wheel and Color List windows. Click on the desired colors and the selected fixtures should follow.
Fixture library
Select Windows > Tryout > Library to open the Fixture Library. Here you can have a look at the fixture definition details, and add your own fixtures if they are not already included.
