You can now connect to the mod-host through the Plugins Manager API. Create a ModHost object with the address that is running the mod-host process. Being in the same machine, it should be 'localhost'

mod_host = ModHost('localhost')
mod_host.connect()

Finally, register the mod-host in your BanksManager. Changes made to the current pedalboard will be applied to mod-host

manager = BanksManager()
# ...
manager.register(mod_host)

To change the current pedalboard, change the pedalboard parameter to mod_host. Remember that for changes to occur in mod-host, the pedalboard must belong to some bank of banks_manager.

mod_host.pedalboard = my_awesome_pedalboard
