“One thing I’ve wanted to try is wireless MIDI. I know you can get MIDI over Bluetooth (there are some rather neat commercial “wireless 5-pin MIDI” adaptors you can buy) and I believe people have used MIDI over Wi-Fi by using ipMIDI (“MIDI over Internet Protocol”).
But I’ve had some cheap nrf24L01 radios for a while and so far have not done anything with them yet, so I thought I’d try to use them as a MIDI link.
As with my I2C experiments, this is a very early (read draft, use-at-your-own-risk, very likely to change) implementation of an RF24 transport for the Arduino MIDI Library.
