Agreed. At someone who works primarily in hardware, it is definitely hard. A midi-to-bluetooth recorder is practically a software project in a fancy box. There is very little physical complexity to deal with here, which is what makes hardware difficult- the interaction between firmware and the "real world".

Congrats though, making a half-million a year business is a massive accomplishment! The headline just irked me a bit, haha (but, it got my attention, so I guess you win there)
