Hi there!
I am working on a Midi - CV/Gate module for my modular synth and figured the teensy 3.6 would be the perfect fit.
I am having a little bit of trouble using the t3.6 as a midi usb host, despite directly copying this example code: https://github.com/PaulStoffregen/USBHost_t36/tree/master/examples/MIDI/InputFunctions
so I figure the problem must be either in my hardware setup, or with the Teenage Engineering OP-1 (my synthesizer I am using)
When I monitor the serial connection, I see the startup message:
"USB Host InputFunctions example"
but when I connect my midi controller (either before or after the t3.6 is powered) it doesn't seem like the t3.6 is receiving any of the midi messages when I press keys on my midi controller.
I know that the OP-1 midi works because I use it with my DAW (FL Studio 12) all the time, no problem, but maybe it doesn't know how to connect to the t3.6? But that's what the usb host library is for right?
Here are links to some pictures of my hardware setup:

I have tested the continuity through the usb cables and the white mini usb end (connected to the synthesizer) has continuity with the usb host port on the t3.6 when everything is connected. This makes me think I must have the cables in the wrong order or something... but as far as I can tell it is supposed to go (from top to bottom in the picture) Vcc -- Red, Data- -- White, Data+ -- Green, ID (for establishing host) and Ground -- both soldered together under the green heatshrink.
I am powering the t3.6 from my laptop at the moment, but when it is finished it will be powered from the 12v rail on my modular synth, stepped down to 5v with a voltage regulator.
I copied the code directly from the example, it compiles without any errors, I've tested the continuity of the entire usb circuit from the mini usb end to the usb host port on the board, I am using arduino 1.8.5, with the teensyduino programmer, and I am using Windows 10.
thanks in advance for any help
