Leprecon LP-1600 Series - Manual (Page 41)

The LP1600 chaser consists of the controls necessary to enter and run chases,
set the rate of the chase, and attach it to a scene. The simplest control is the
On switch, which enables all other chaser functions. The level pot is located in
the lower left corner of the board, this control allows the output level of the
chases to be altered. A chase can be on and running, and the output level
brought up slowly with the level fader.
The buttons labeled Run and Step are used to start and stop the sequence.
Pressing the chase Run switch will light the led next to the switch, and start
the chase pattern advancing at the set rate. Pressing the chase Run button a
second time will quench the led, and stop the pattern on the current step.
When the chase is not running, pressing the Step button will advance the
pattern one step. If the chase is running, pressing the Step button will stop the
chase for as long as the button is held down. The led next to the Step switch
flashes each time the chaser advances one step.
The rotary switch labeled Pattern selects which of the 11 different chase
patterns will be run by the chaser. Chase patterns 1 through 4 are pre-
programmed, chases 5 through 11 must be programmed for each step before
they can be used. See the section Recording New Chases for more information.
The pattern select position labeled auto is used only if chase patterns have
been attached to Presets or Stack Cues. This position allows the LP1600 to
turn on and off any of the chases automatically with the Preset or Cue Stack
scene. See the section Linking Chases to Scenes for more information.
The Rate control sets the speed at which the chaser advances from step to step.
Turning the control clockwise increases the rate, indicated by the flashing of
the led next to the Step switch. Turning the control counter-clockwise slows
the rate of advance. The rate control has a special function when set to the
minimum, or fully counter-clockwise position. This position disables the
internal clock, and uses an external audio signal to advance the chaser from
step to step. More information on this is available in the section labeled Audio
Input.
6.3. Recording New Chases
The chaser section of the LP1600 allows for seven custom chases to be
programmed by the user. Each of these patterns can consist of up to twenty
steps, each consisting of any combination of channels at any level. These
programmable chases are available on patterns 5 through 11.
To record a custom chase:
1) Set the selector switch to one of the patterns 5 to 11. The chase cannot be
running while steps are recorded.
2) Press the Chaser menu button. The LP1600 will display a
