Hi Yuuichi, i found you to be knowledgeable in coding based on my github search. I am a newbie, not even a coder so I got interested in making my DIY midi controller for MG300 (i thought to play around with existing codes but failed to find one). I have been struggling to find online for arduino code for many weeks, your test code is the only code that was able to communicate with MG300... it automatically makes looping patch change. I am using UNO + USB Host Shield on my project with 4 buttons and LEDS hoping I can assign a specific patch number to each button. Can you please help me even with just couple of working buttons based on your sample code? thanks

Okay got it. Thanks for the link provided

Hello.
I hope you can help me since I am really not sure how to approach it properly.

I purchased the NUX MG300 and a MIDI switching device called Melo Midi Commander, together with Bluetooth MID send/receive devices called MS1.

From what I see on this page, I need to send the texts written by Mr. Yuiixhi to MG300, but how do I do that?
I am not very experienced in this data-transmitting endeavor between PCs and devices, so it would be great if you could point me in the right direction.

I will be waiting for your reply.
