This video is interesting but... it is a load of pseudo-science bollox.
What these guys are *apparently* measuring is not the speed of their wireless MIDI device but the speed of the combined system from note on to noise out.
This is a combination of the response of the master keyboard, the midi interfaces, the computers they are using including all their 'settings' and software.
What they could measure with their fancy oscilloscopes is the time difference between the midi on pulse sent and received by wired or wireless.
Even this would tell them nothing.
What they should measure is the MIDI choke... The point at which the whole system melts down into note-on chaos.
Considering it's based on 1980s technology, MIDI is even today a remarkably versatile and effective protocol for sending information between electronic musical instruments... It is flawed of course. But most of the flaws are caused by trying to make it do things that is was never designed to do.
It is a nonsense to say that
- wireless MIDI is faster
- or wired is faster
- or writing in in crayon and sending it by UPS is faster!
It's either 31250 bps or it's not MIDI.
Perhaps these blokes have developed a wireless midi protocol that is rock solid reliable, doesn't introduce too much latency in the signal and doesn't choke if you send to much continuous controller information and doesn't drop data. Good for them if they have.
But faster... My Stripy Arse!
