-====== Sequences Understanding ======
-===== IMPORTANT NOTE =====
-This article assumes you're running FreeStyler on a PC using a little endian processor (x86 core)
-You may have to consider swapping the data on a big endian processor (ned xcheck)
-===== What is a sequence file (*.chb) =====
-The sequence file is generated by the sequence editor. See [[sequence_editor|the sequence editor]] for further information.
-This file contains the DMX values and other informations to allow Freestyler to play back your scenes.
-===== Structure of the sequence file =====
-The sequence file is divided as below:
-**Word0:** Number of steps contained in the file
-x0200: Sequence has 2 steps
-Then all steps are added with the following syntax:
-all steps are using 1618 words (1 + 1 + 1536 + 79)
-**Word1:** Time for the fade (multiplier for 500ms)
-x0100: (fade time is 500 ms)
-x0300: (fade time is 1500 ms)
-**Word2:** Time for the scene (multiplier for 100 ms)
-x0A00: (scene time is 1000 ms)
-x0D00: (scene time is 1300 ms)
-**Word3 to Word1539 (included):** 3 words per DMX channel where
-  * First word is the DMX value for the channel
-	From 0x0000 to 0xFF00
-	(0x0100, 0x0200, …, 0x7F00, 0x8000, …, 0xFE00, 0xFF00)
-  * Second word is the usage of the DMX channel
-x0100 = Fade
-x0200 = Snap
-x0300 = OFF
-  * Third word seems to be unused for now
-	Always 0x0000
-**Word1540 to Word1617 (included):** Behavior not understood. Values are not changing whether cues or buttons are used. I have today no clues for that.
-===== How can I see/edit the sequence file content =====
-Get an Hex editor such as PSPad for example and open the file in HEX format.
