Pybristol is a lightweight GUI for bristol, based on python3 and tkinter. bristol by itself is a very powerful classic synth emulator, but its engine is cli based, which makes it unhandy to use, especially when the artist receive a sudden inspiration, or when she needs to change and try different synths fast. Also it will probably be a good idea, to add pybristol as a recommend, when bristol is installed.
