Splitting MidiFile Tracks to diffrent MidiFiles

General JUCE discussion

I have a midiFile with 5 different tracks, my goal is to separate each track into a different midiFile:
this is what i have done by now, only the first one is working but the rest no so much:

std::unique_ptr<FileInputStream> fileStream(file.createInputStream());
if (fileStream == nullptr || !fileStream->openedOk())
{
    DBG("Failed to open file stream!");
    return;
}

MidiFile midiFile;
if (midiFile.readFrom(*fileStream))
{
    DBG("MIDI file successfully loaded!");

    // Get the time format
    short timeFormat = midiFile.getTimeFormat();

    // Store global meta events
    MidiMessageSequence globalMetaEvents;

    // Extract global meta events from the first track
    if (midiFile.getNumTracks() > 0)
    {
        const MidiMessageSequence* firstTrack = midiFile.getTrack(0);
        for (int i = 0; i < firstTrack->getNumEvents(); ++i)
        {
            const MidiMessage& msg = firstTrack->getEventPointer(i)->message;
            if (msg.isMetaEvent() && !msg.isTrackNameEvent() && !msg.isTextMetaEvent())
            {
                globalMetaEvents.addEvent(msg);
            }
        }
    }

    for (int i = 0; i < midiFile.getNumTracks(); i++)
    {
        MidiFile singleTrackFile;
        singleTrackFile.setTicksPerQuarterNote(timeFormat);

        // Add global meta events to the new file
        MidiMessageSequence newTrack = globalMetaEvents;

        // Add track events
        newTrack.addSequence(*midiFile.getTrack(i), 0, 0, midiFile.getLastTimestamp() + 1);

        singleTrackFile.addTrack(newTrack);

        // Get the name of the track (if available)
        String trackName = "Track_" + String(i + 1);
        for (int j = 0; j < newTrack.getNumEvents(); ++j)
        {
            const MidiMessage& msg = newTrack.getEventPointer(j)->message;
            if (msg.isTrackNameEvent())
            {
                trackName = msg.getTextFromTextMetaEvent();
                break;
            }
        }

        // Sanitize the track name for use as a filename
        trackName = File::createLegalFileName(trackName);

        File newFile = file.getSiblingFile(trackName + ".mid");
        if (auto outputStream = std::unique_ptr<FileOutputStream>(newFile.createOutputStream()))
        {
            singleTrackFile.writeTo(*outputStream);
            files.add(newFile);
            DBG("File created: " + newFile.getFullPathName());
        }
        else
        {
            DBG("Failed to create output stream for: " + newFile.getFullPathName());
        }
