The toggle button
Sound-To-Light Section
Please Note:
Some on-board sound for laptops and desktops do not have this facility, and a third party
Soundblaster compatible or ASIO audio card / interface may be required to make use of these
features.
When music is playing through, or audio is being fed into, the ShowMagic desk, the volumes of
particular frequency bands in the music can be seen in 5 meters which are provided on the sound-to-
light section - low frequency
LF
, low-mid frequency
LM
, high-mid frequency
HM
, high frequency
HF
and overall volume peak
PK
. These work in a similar way to the meters on an audio spectrum
equalizer. Bass and drum sounds tend to affect the
LF
and
LM
meters and other higher tone
instruments tend to affect the
HM
and
HF
. The overall volume peak meter
PK
is a compound effect
of all the frequencies. The lowest and highest frequency for each frequency band can be selected
between 30hz and 16Khz.
There are eight sound-to-light 'slots' that can be assigned to any of the available DirectSound
(
Dsnd
) or
ASIO
input and output channels that are detected by ShowMagic. To set up these slots
use the '
Options > Other Settings > Audio / ASIO Settings
' menu item.
The sound-to-light meters can be used to activate scenes in a lighting chase as described in
"Sequence Settings", p.113, FX scenes as described in "FX Generator", p.73, and Colorscene
frames as described in "ColorScene", p.85. A blue LED in each meter will be triggered (and will
jump to the top of the meter) when the volume (shown as green LEDs) in that frequency range
reaches a threshold (
TH
) selectable between 10% and 90% of the volume. This setting applies to all
the meters. Any settings displayed in blue, such as the ones above, can be adjusted by holding down
the
[Ctrl]
key whilst left / right-clicking on them.
A response setting (
RP
) between 25% and 100% is also selectable for each meter independently and
this determines how soon after a blue LED has been triggered that it can be triggered again as
shown below:
