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
