AudioIO | modular component system for building complex instruments | Audio Utils library

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:

I'm using AudioUnit to playback audio from a TeamSpeak server but when I call AudioUnitInitialize on the iOS Simulator, I'm getting constantly the macOS prompt to allow microphone access even if I want to playback only.

On a real device everything works fine without any native prompts but it is really annoying when running the app in the simulator because this prompts appear every time I run the app.

So I am trying to implement the Superpowered library in Swift, and am getting stuck around initialisation with a callback. How would I convert that line:

I am trying to create android app with Superpowered SDK, which would allow me to redirect mic input to headphones with added reverb effect to mic, to simulate huge room effect. I found this repository with code snippets: https://bitbucket.org/snippets/kasurd/Mynnp/nativesuperpoweredrecorder-with, but I can't make it working. This is my current code:

I implemented the audio playback successfully but a frequent problem comes up where a sharp auditory glitch occurs when "next song" is clicked from JAVA. This sound glitch elapses approx. around 100ms. And occurs more frequently before the next song starts playing.

Please importantly note this: I call "delete" on every variable class and "free" stereobuffers (setdestroyallthreads) at the end of every playback, then "process"(process) method before every playback starts.

From Java, the transition sequence looks like this;
