[sdiy] rtpMIDI questions

[John Speth]

It's a shared WiFi system at my home (one laptop, four phones, two 
Rokus). However, my WiFi system uses both 2.4 GHz and 5 GHz for 
over-the-air transmissions. About half my devices are using WiFi use 
2.4G and half use 5G I'm not sure how that plays into my results. The 
nearest house is about 50 feet away from my house. Is it possible that 
WiFI radiation from a nearby house can interfere with my WiFI. That 
seems plausible to me.

Are you saying that WiFi loading could have been the reason for my 
observations? I suppose it's plausible. Could there be other causes?

I realized soon after I started testing that I may have higher 
expectations than is possible with WiFi. I don't know any way of 
debugging this. Based on my observations, I believe reliably delivered 
time accurate MIDI over WiFi is not possible because of occasional 
timing errors. Kinda shows the RTP part isn't really realtime enough for 
MIDI.
