Arduino-based rotary encoder board, part 4.
On the software side, I’m going to skip the details of controlling the SPI and move on to some blue sky thinking about how I hope to program this beastie.
Typically a MIDI controller like this could be remotely programmed using Sysex messages. We’ve seen an example of this on the forum recently, with the Yamaha TX81Z.
There ought to be a default value for each encoder, though, and this should be compliant with something like Mackie Control or HUI. This would make it interoperable with a wide range of DAW software.
