Hi ctrldev driver developers!

Those of you developing ctrldev drivers for zynthian will be happy to know that i just pushed to vangelis (testing branch) the multi-driver feature that allows choosing among a list of drivers for the same device.

Some tips:

- You simply drop your driver in the _zyngine/ctrldev_ folder and reload zynthian UI. You don’t need to edit the “ **init**.py” that has been removed from this folder.

- Remember that module name and class name have to be the same.

- Only one driver from the list can be loaded for each device.

Regards,

---

Awesome, I just saw the commit.

Looks like we are invited (but not required) to add the Class properties `driver_name` and `driver_description`. Are these used in the UI?

Yes, they are in use in the UI, although i’ve not updated for using in the existing drivers … yet!
