MagicQ User Manual 56 Version 1.4.9.0
Limit enables a maximum level to be set for the channel whilst retaining the normal linear dimming curve.
When dimmer curve is set to “Limit” the channel has a linear curve up to the maximum value rather than
using the normal linear curve and then stopping at the maximum value.
Offset enables an offset value to be applied to a channel – this can be useful if a moving light is not
calibrated correctly or it has been moved. When dimmer curve is set to “Offset” then the minimum value
specifies the offset to be applied. When a channel value exceed 255 then it wraps back to 0.
5.10 Dimmer curves
MagicQ supports
10 user dimmer curves that can be selected in the Patch Window, View Chans view.
User dimmer curves are specified in files of format csv (comma separated variable) with filename
dimmercurveuser1.csv, dimercurveuser2.csv etc… stored in the show/heads folder.
The files consist of 256 lines each with a value between 0 and 255. These files can be generated in a
spreadsheet (e.g. Microsoft Excel) and saved as csv format.
User dimmer curves are not stored into the show or settings files. Each console that uses user dimmer
curves must have the curves stored in the show/heads folder.
In the CSV file the line after the last line of data (the 257
th
line) can hold a name for the curve which is
then displayed in MagicQ. The name has a maximum of 15 characters.
5.11 Changing the DMX channels of dimmers and heads
Dimmers and Heads can be moved to different channels as required. When they are moved all the
programming and palettes associated with them also moves to the new channels.
In VIEW HEADS, simply edit the DMX field with a new address.
In VIEW CHANS, press the MOVE button, then select the channel field of the Dimmer you wish to
move. Then select the channel field of the destination. Heads are moved in the same way as Dimmers –
for the source channel select any of the channels of the Head.
