action’s value or intensity is higher than the current value controlling that channel. That's great when

controlling groups of dimmers with multiple master faders but not so great when controlling moving lights

that don't really care how high the intensity of a channel is since you are controlling things like wheels and

mirrors.

There are several methods of master fader operation used by the many different brands of lighting

controllers out there. The method chosen for the SD2 uses LTP and gives you manual control of the

crossfade of all channels within a scene. It also gives you the ability to "pull back" the fader allowing you to

move the crossfade in both directions. Some consoles use LTP but only allow you to advance the fader

towards the destination but do nothing if you pull the fader back. To allow "pull back" the SD2 takes a

snap shot of all channels that are included in the scene to set the "pull back" values. Any channels that are

not part of the scene won’t be affected. When you reset a scene master fader by moving it to the bottom

then move it up past the trigger point, which is just slightly up from the bottom, the snap shot is saved.

Also any chases in the scene are started. This means that you can move the scene master fader up and

down and the lights will move between the current values and the values of the scene assigned to the

master.

This can cause problems if you are trying to operate the scene masters on the SD2 as dimming masters like

on an HTP console. When a scene master on the SD2 takes control of a dimmer that is already on, it will

take a snap shot of the current "on" value and use that as the pull back value. When you pull the master

back the dimmer doesn't go to 0, it goes to whatever the start value was. To work around this problem and

make a master fader that controls dimmers only, you must first record a scene for that master that only

contains the dimmers that you want to control. Always start building the scene by clearing all channels first.

Do this by holding down the black switch till its led goes off. This clears the scene editor. Next start adding

dimmer channels by setting their levels to full, don’t change any other channels or they will be included in

the scene. Also don’t remove dimmers from the scene by pulling their levels down to 0, they will still be in

the scene and they will have the value 0. Also be aware that if two scene masters are sharing some of the

same dimmer channels there can be problems when you try to use them both together. Moving one while

the other is up will take a snap shot of those shared channels at some value other than 0.

MIDI

Show Designer 2 allows you to use MIDI to call scenes using a MIDI sequencer so that you can

synchronize lighting to a MIDI performance. The scene page and number is encoded in a MIDI message

that is sent to the Show Designer’s MIDI output when a scene is selected using the number switches or the

“go” switch. The “black” switch also sends a MIDI message allowing you to record a blackout or blackout

restore. When that same MIDI message is returned to the MIDI input, that scene will be called. Since the

Show Designer 2 uses its own type of MIDI message to record scene changes it is recommended that you

use the Show Designer 2 to record the performance.

The Show Designer 2 uses MIDI continuous controller messages to send and receive scene changes and

blackouts.

The message format for scene changes is as follows:

0Bxh pp nn, where x is the MIDI channel (0-15 decimal), pp is the scene page (0-98 decimal) and nn is the

scene number (0-47 decimal).

The message format for blackouts is as follows:

0Bxh nn vv, where x is the MIDI channel (0-15 decimal), nn equals 99 decimal and vv is non zero for

blackout on and zero for blackout off.
