Once that load_config_env has loaded up all the environmental variables that hold the actual state of a zynthian. It's all in there and is used to define the context that the zynthian runs under.

−Quite how a specific environment file is exposed to this process depends on the config, so mechansisms like MIDI configs define these states depending on wether or not a user has defined their own specific MIDI configuration or indeed several. Zynthian is basically a device for starting and stopping jack instruments and interacting with the engines once they are running.

The GUI controls those interactions.
The GUI controls those interactions.
+So the lines in the zynthian.sh file that start up the python elements are :
+
+splash_zynthian
+load_config_env
+
+ while true; do
+ # Start Zynthian GUI & Synth Engine
+ cd $ZYNTHIAN_UI_DIR
+ ./zynthian_main.py
+ status=$?
+
+We then start up the python file zynthian_main.py
+This is a small file that acts as an entry point to the zyngui object that is the base of all gui zynthian objects.
+
+
+ # Zynthian specific modules
+ from zyngui import zynthian_gui_config
+ from zyncoder.zyncore import lib_zyncore
+ from zyngui.zynthian_gui import zynthian_gui
+ from zyngui import zynthian_gui_keybinding
