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.
