number of scenes, is indicated at the bottom of the dialog.
Record Realtime - Click to start recording - the progress bar at the bottom illustrates remaining
recording time. Once the specified scenes are recorded, a new dialog will appear. Click Yes to convert
the recording to a sequence. Note: the new sequence created will overwrite the contents of the
current sequence so if the DMX output created is generated by the current sequence it may be a good
idea to save the source sequence before recording.
Sync start with Sequence playback - use this option to synchronize the start of recording with the
start of sequence playback. First enable the option, then click Record Realtime. Finally, click either
playback button on the sequence control to start simultaneous sequence playback and recording.
To record even more complex setups (e.g. using cues and generic DMX macros) setup the 'program'
in a cue list and add a hotkey function (e.g. Sequence playback fwd) to start recording. Note that the
cue list may add a slight delay between commands, so it may be a good idea to record one or two
extra scenes so that the first couple of scenes can be deleted once the new sequence has been
created.
Tips:
Recording macros
To record a pan/tilt macro or Generic DMX macro, the total recording time should be as close as
possible to the macro cycle time. When using different cycle times, the shorter time(s) should be a
fraction of the longest cycle time (e.g. 1/2 or 1/3 of the longest cycle time). This way the resulting
sequence always contains the entire macro cycle. There is no difference between recording a macro
with a short cycle time with a fast sample rate and recording the same macro with a long cycle time
and a lower sample rate.
Recording sequences for the 2510
Since the 2510 playback controller cannot fade DMX values or play back sequences containing
macros, real-time recorded sequences containing many scenes can be used to emulate these
functions in the 2510. To re-produce a smooth movement originally made through a fade or macro the
sequence should be recorded with a fairly high sample rate (2-10 scenes pr second or even 20 scenes
pr second) and the scene time of the sequence should be fairly short. The high sample rate and short
scene time in combination will emulate the real-time DMX calculations usually made by LightJockey
in the 2510. The actual sample rate and scene time needed depends a lot on what type of fixture is
being used as well as individual fixture effects.
Creating sequences with long fades
Normally, scene fade times are restricted to 60 seconds. If very long fade times are required (e.g. 60
minutes) use the record real-time function to break the transition up into multiple scenes.
Example, making a fade lasting one hour:
First prepare the sequence containing the fade (e.g. a CMY from 0% saturation to 100% saturation).
Set the scene and fade times to 6 seconds.
Next set the real time recording sample rate to 10 scenes pr second and the total number of scenes
to 60 (or 20 scenes pr second and 120 scenes for double resolution). Record and convert to a
sequence using the sync with sequence playback option. Set the sequence scene time to 60
seconds (or 30 if recorded with double resolution). The total sequence now contains the entire
transition and plays back in one hour.
Depending on type of effect and fixture used, it may be necessary to increase the resolution to avoid
visible 'bumps' when a DMX new value is sent to the fixture. 20 scenes/second, 256 scenes total and
a scene/fade time of 12.8 seconds will create a sequence containing all values in a 8-bit control
channel fade from 0 to 100%. Use scene time to control the sequence playback time (a scene time of
14 seconds with 256 scenes makes the time for one sequence loop very close to one hour).
Sequence fades
While not strictly part of the sequence control, the sequence fades control offers the possibility of
modifying the fixtures fade state on a more global sequence level than just using the fade state button
for each effect (control channel). The control is accessible from the fades menu of most fixture
