Thanks a lot herr_prof for the adapter explanation and catskull for the reference link and altered code!
After relearning and newly learning a bundle about MIDI and Arduino, I've got this code installed and running!

-Installed Teenseyduino
-Set board to Teensy LC and USB Type to MIDI
-Cleared EEPROM with the first sketch and installed the Arduinoboy with altered mGB channel with the second sketch

I agree profusely on getting more fanciful equipment as I go, I'm glad this gives me a good base to learn off of for a start.

Last, for changing the mGB channel options again in the future, this was the line you changed right catskull?

   1, 2, 3, 4, 0, //mGB midi channels (0-15 = 1-16) 

Hello Chip Music!

Could I please get some help with altering my TeenseyBoy Pro such that it reads MIDI channel 1 as the command for mGB Poly mode, instead of the default MIDI channel 5?

I just got a TeensyBoy Pro from Catskull Electronics and it's working swell! However, because I'm using a RockBand Keytar to do this, I'm locked into MIDI channel 1. I've gotten the Arduinoboy Editor running in Max Runtime 6. However, neither USB or my USB to MIDI adapter lets the editor find my board.

Does anyone have a recommended USB to MIDI cable/adapter?
Or can anyone point me to how I can edit the Arduinoboy .ini files to make this change and download it to my Teensyboy Pro?

Thanks a lot!


*Edit: Figured out I was downloading the github webpage for the editor file, not the the actual editor file code!
-USB to MIDI cable I tried  (https://www.amazon.com/gp/product/B01JL … &psc=1)
It seems broken, since I've proved everything else in my setup.
