Trouble receiving midi message

[richy486]

Using a Teensy 3.2, I can compile and upload the sketch fine.
It goes through the startup animation on the LEDs.
I can select a mode with the button.
It even remembers the mode when I restart.

I'm trying to use mGB mode.
But when sending midi from my computer, using Live, through USB, I don't get any status LED changes (or any sound on my gameboy).

The settings in the Arduino IDE are:
Board: "Teensy 3.2 / 3.1"
USB Type: "MIDI"
CPU Speed: "96 MHz (overclock)"
Optimize: "Faster"
Keyboard Layout: "US English"
Port: "HID=#### MIDI (Teensy 3.2"

I can also see a "Teensy MIDI" in my Audio MIDI Setup on macOS and can see "Teensy MIDI" in Live as a "Midi to" output.

I've used the same pins as in the original code. I updated all the libraries in the Arduino IDE. I tried other USB Types to see if there was some serial debugging info printed.

Here is a picture of my breadboard layout.

I also have an Arduino UNO with a which I can send midi to fine with a USB to DIN 5 cable.

I'm not sure where I have gone wrong, since the start up and mode selection appear to work. Does anybody have any ideas?

Can you try this code version to see if we broke anything recently? I do not have a Teensy 3.2 Aboy currently to test: https://github.com/trash80/Arduinoboy/tree/5db4ed8c620e4db0a6a5803c619055df93d006a6
