This can be useful +to take advantage of additional protocols implemented in OLA. This backend is currently marked as +optional and is only built with `make full` in the `backends/` directory, as the OLA is a large +dependency to require for all users. + +#### Global configuration + +This backend does not take any global configuration. + +#### Instance configuration + +| Option | Example value | Default value | Description | +|---------------|-----------------------|---------------|-------------------------------------------------------| +| `universe` | `7` | `0` | OLA universe to send/receive data on | + +#### Channel specification + +A channel is specified by it's universe index.

It is thus marked as optional and only built when executing the `full` target +within the `backends` directory.
