Slide 1 Computer Control The Gig

Slide 2 What features in the program can help us run the lighting & smoke effects? The computer is good at controlling effects for a band It is fast It can switch lots of outputs on/off It has a memory that can save sequences of programmes

Slide 3 What lighting effects are there? Teacher resource 6.1 What other effects are there? How could a computer control these effects?

Slide 4 Here are two simple sequences

Slide 5 If we combine them, the flowchart becomes complex and we have to re-write boxes-

Slide 6 Today you will: Use flow chart symbols Use precise control words Structure instructions in sequence Use a sub-routine to make your programs more efficient Create a sequence for a light show

Slide 7 By using a sub-routine, we can build short programs that can be re-used…

Slide 8 What is a simulation? A simulation is a special type of computer model which mimics a real life situation

Slide 9 Where are simulations used? They are often used to train people how to deal with situations that are too dangerous, expensive or difficult to practise for real. They can also be used for games Pilots train in fight simulators Astronauts use simulators to mimic conditions in space Seismologists use simulations to predict the effects of earthquakes

Slide 10 Advantages of simulations Cheaper than doing it for real No equipment is damaged People are not in danger If there is something wrong with the model things can be changed quickly and cheaply

Slide 11 Limitations of simulations The results of the simulations are only as good as the model No simulation can take into account every situation that can happen in real life

Slide 12 Using a simulation to create light sequence for a gig The expense of creating a light show on a stage means that you MUST design your system first The best way to do this is by using control software to mimic the real thing so if you make a mistake it can be edited easily
