I use superpowered, I need send midi note to a controller midi.
The problem is that I saw a function send(int deviceID, unsigned char *data, int bytes); Where in their source code say:

deviceID: Device identifier.
data: Raw MIDI data.
bytes: Number of bytes.

I don't know the values that I need put exactly on data and bytes to work.
The raw midi could be 0x80 - 0x48 - 0x00(start of C4 note, pitch= 72, See values)
And the bytes 1001nnnn0kkkkkkk0kkkkkkk(note on event See values) for example?
Something like that:

SuperpoweredUSBMIDI::send(deviceID, reinterpret_cast(0x80 - 0x48 - 0x00), 1001nnnn0kkkkkkk0kkkkkkk);

The problem that always crash, and I can't debug or get the error for the reason that I use the mobile with otg to replicate the error.
When I find a solution, I will put it as soon as I can.

I'm newbie with markdown, sorry for any mistakes and my English grammar.

Edit: I'm using the example project that they have on GitHub for testing purposes, specifically the simpleusb project. (source)

I make a small modifications and work, but with this specifically I try with many ways and nothing. I think this simple macrochange at least could work if I insert well the values
class simpleusb.cpp:
