Hello there, I've try to use this fesiable code to read the data, but I found the port name "Head Tracker" could be wrong since the mido report it is a unknown port.

It works for me (tested on MacOS with Intel). Which port names are shown if you do something like the following code? And you are trying to read data from a Supperware tracker?

print("Available backends:", mido.backend.module.get_api_names())
print("Available input names:", mido.get_input_names())
print("Available output names:", mido.get_output_names())
print("Available ioport names:", mido.get_ioport_names())

Yes, I just brought a supperware tracker for binaural rendering, it seems the original input name is not correct. Thanks for fixing this problem
