I have been having this issue (maybe non-issue) for some time.
Here is my set up:
Teensy 2.0 MIDI Device
Late 2013 Macbook Pro
I am using a Teensy MIDI device in Pd.
If I connect the Teensy device, then launch Pd, I get the following error
in Pd's print window
could not open midi input 0 (Teensy MIDI): PortMidi: 'Invalid device ID'
could not open midi output 1 (Teensy MIDI): PortMidi: 'Invalid device ID'
Under my MIDI settings I have "Teensy MIDI" selected both as my input and
If I re-select "Teensy MIDI" in both dialogs of the MIDI preferences menu,
and hit OK the same error message will reappear in Pd's print window.
If I select "none" for both input and output I do not get any error
Though I get this error, it seems to not effect the use of the device in
When I connect the device to a windows machine, I don't have this PortMidi
I have also connected this device to my iPhone using MobMuPlat, no issues.
Any advice would be helpful.
