How to write MIDI Messege seen in Android MIDI Scope

Projects Programming
1

I saw this MIDI messege in Android Midi scope screen .when my user bank is select from Preset Bank.

USER1

i tried it in code to resend to my device like below

  byte USER[24] = {0xB0,0x00,0x55,0x90,0x20,0x00,0xC0,0x00,0xF0,0x41,0x10,0x00,0x00,0x3A,0x12,0x01,0x00,0x00,0x01,0x55,0x00,0x00,0x29,0xF7};  
                     MIDI.sendSysEx(24,USER,true);

but i did't get my User Bank.
are you seeing here missing in my code????

Try sending just the data bytes. the MDI.h library should take care of the sysex start and end.

The 'cc control' & 'note on' should be ignored regardless.

byte USER[12] = {0x00,0x00,0x3A,0x12,0x01,0x00,0x00,0x01,0x55,0x00,0x00,0x29};  
                     MIDI.sendSysEx(12, USER, false);

Edit looking at MIDI.h the last parameter is 'in array contains boundaries' which in this case should be false as is the default)
If the program change is also required then you should send that using

MIDI.sendProgramChange(0, 1);   // PC to 0 on channel 1

Thank you for reply,
But

byte USER[12] = {0x00,0x00,0x3A,0x12,0x01,0x00,0x00,0x01,0x55,0x00,0x00,0x29};  
                     MIDI.sendSysEx(12, USER, false);

Not working,,

But compiles ?
Ok i have been digging further. For some reason MIDI.org is not as available as it used to be but from MIDI.hpp

template<class Transport, class Settings, class Platform>
MidiInterface<Transport, Settings, Platform>& MidiInterface<Transport, Settings, Platform>::sendSysEx(unsigned inLength,
                                                    const byte* inArray,
                                                    bool inArrayContainsBoundaries)
{
    const bool writeBeginEndBytes = !inArrayContainsBoundaries;

    if (mTransport.beginTransmission(MidiType::SystemExclusiveStart))
    {
        if (writeBeginEndBytes)
            mTransport.write(MidiType::SystemExclusiveStart);

        for (unsigned i = 0; i < inLength; ++i)
            mTransport.write(inArray[i]);

        if (writeBeginEndBytes)
            mTransport.write(MidiType::SystemExclusiveEnd);

        mTransport.endTransmission();
        updateLastSentTime();
   }

    if (Settings::UseRunningStatus)
        mRunningStatus_TX = InvalidType;

    return *this;
}

and midi_Defs.h

        SystemExclusive       = 0xF0,    ///< System Exclusive
	SystemExclusiveStart  = SystemExclusive,   ///< System Exclusive Start
	SystemExclusiveEnd    = 0xF7,    ///< System Exclusive End

I deduced that the SysEx message is actually everything in between the 0xF0 and the 0xF7
So that makes your message 14 bytes + start and end bytes.

byte USER[14] = {0x41, 0x10, 0x00, 0x00, 0x3A, 0x12, 0x01, 0x00, 0x00, 0x01, 0x55, 0x00, 0x00, 0x29};  
                     MIDI.sendSysEx(14, USER, false);

should do the trick and

byte USER[16] = {0xF0, 0x41, 0x10, 0x00, 0x00, 0x3A, 0x12, 0x01, 0x00, 0x00, 0x01, 0x55, 0x00, 0x00, 0x29, 0xF7};  
                     MIDI.sendSysEx(16, USER, true);

should also work.
