Move fader 1 above zero activates cue 1.

Move fader 1 back to zero has no effect.

Move fader 1 above zero again deactivates cue 1.

Now we realize a lot of you are sitting there and saying I don’t get it! What’s the purpose of this? I’ll
never use ALT mode.
Well, if instead of faders on a manual controller, you think of using an automatic dmx input signal
from a ‘master controller’ (a show controller) then the ALT mode is a real asset. Here, all you would
do, is send a flash signal to turn on cue 1. Then later in the show, you would send it a second flash
signal to turn it off. There would be no need to keep the signal latched on to keep the cue active.
Kinda Neato!!!

Midi NORM mode.
If the object is assigned to a midi note, it is activated whenever a Note On is received by the CP-100.
With midi, usually it is the case that, the midi device will normally keep sending the Note On until
you tell it to turn off. (Just like the fader example with DMX triggers, if the fader is up the cue is
active if you want to deactivate it pull the fader down). To deactivate a Midi triggered cue, you must
send a signal to turn the Note Off. So don’t forget to send the Note Off command, otherwise you are
going to just piling objects on top of one another! It not a pretty sight when it goes wrong!

Midi ALT mode.
In the Alternative mode the CP-100 makes life even easier! You don’t have to remember to send the
Note Off command! The Midi Note On toggles the object on and off. Midi Note Off signals are
ignored.

Midi Note names and numbers.
If you studied any musical instrument at school you know the principle of notes and octaves.
Remember Middle C?! Well the only problem with that system is that you have to remember the note
and the octave. So you have to write down things like “octave 2, D sharp”. There is an alternative to
this and that is Midi numbers. The numbers system is just a map crossover for the Midi note names.
The Midi note that corresponds to our “octave 2, D sharp”, would be number 15. At the back of the
manual is a Midi names and numbers map to help you.

Midi Channels.
Midi channels are just like DMX ports. Each DMX port can control 512 channels. If you need more
than 512 channels of DMX, you need a second DMX port.
With Midi the maximum number of notes (which is the equivalent of DMX channels) is 127. So there
are 127 notes per Midi ‘port’. The correct terminology for a Midi ‘port’ is called a Midi channel.
There is also a limit to the number of Midi channels that you can have and that number is 16.
So in summary available to you using Midi is 16 channels each channel having 127 notes.


Linking CP-100s.
Linking CP-100s (Yes, it has been done!!) is done using the Midi In and out ports on the back of the
board. The Midi output port echoes everything received on the Midi input port. This is a software
“THRU” function, so there is at least a one byte time delay.

Summary of Triggers.
In general, whenever a trigger (DMX-input or Midi Note On) is received, the CP-100 scans all its
objects (cues, chases, macros and hotkeys) and activates any that have matching channel and note.
Cues are activated by crossfading them in, at their programmed crossfade time. Chases and macros
