I'm working on an 8x8 MIDI merger using a Teensy 4.1 with Ethernet kit. I'm using the NativeEthernet library because it works. I also have Bonjour working, as I can see the Teensy with both my Macbook Pro and Windows machine using Tobais Erichsen's rtpMIDI software. Both the Mac and Windows computers are sending the initialization request to the Teensy and I can see the packets using Wireshark. I also am seeing the UDP packets from Teensy, as it's dumping the UDP packet, From IP, port number, and size. I'm seeing 12 IN commands followed by the BY command before the initiator gives up. I am not seeing the OK command from the Teensy board followed by the timing synchronization routines. Where would I find the init routines to establish the rtpMIDI socket? |

Did you try this example? https://github.com/lathoub/Arduino-AppleMIDI-Library/blob/master/examples/AVR_Initiator/AVR_Initiator.ino |

I had not tried that because it looked like it was the Initiator not the Receptor. However, on a whim I commented out the sendInvite and remote IP address section, changed it to NativeEthernet library, and added the Bonjour stuff and got it to work. I was able to connect with both the Windows and Macbook Pro computers and got a latency of 0ms on both machines. Interestingly, it only sent the note on/note off commands when the Macbook was connected. That may be because that's the one in the music studio with Cubase running. I got the random notes triggering Mordartt Pianoteq Bosendorf and Spitfire's BBC Symphonic Violin. I have most everything in the AVR_Initiator in my app, so I'll have to see if I'm compiling with different libraries or what other differences there are. Thanks for the tip! |
