I thought the UnO firmware was free?

It is. However, the FCB1010 firmware cannot be updated over MIDI; you need to "burn" the new code into an EPROM using an dedicated burner, which means:

1. Either you buy the required tools (costly and complex, especially if it's just for this one update).
2. Or you can order a ready-made EPROM here, by the way directly supporting my work!

The total cost of this second option is 16 EUR, with free worldwide shipping.
Here is a photo of the UnO package you'll receive.
