Hi, I have been using the USB MIDI library, with some success. Recently, however, I have been trying to add support for midi clock and transport messages, like this: - <<code>> // create messages /** Create a Clock message * @returns A MIDIMessage */ static MIDIMessage Clock() { MIDIMessage msg; msg.data[0] = 0xF8; return msg; } /** Create a Clock message * @returns A MIDIMessage */ static MIDIMessage Start() { MIDIMessage msg; msg.data[0] = 0xFA; return msg; } /** Create a Clock message * @returns A MIDIMessage */ static MIDIMessage Continue() { MIDIMessage msg; msg.data[0] = 0xFB; return msg; } /** Create a Clock message * @returns A MIDIMessage */ static MIDIMessage Stop() { MIDIMessage msg; msg.data[0] = 0xFC; return msg; } <</code>> and: - <<code>> /** MIDI Message Types */ enum MIDIMessageType { ErrorType, NoteOffType, NoteOnType, PolyphonicAftertouchType, ControlChangeType, ProgramChangeType, ChannelAftertouchType, PitchWheelType, AllNotesOffType, ClockType, StartType, ContinueType, StopType }; /** Read the message type * @returns MIDIMessageType */ MIDIMessageType type() { switch (data[1]) { case 0xF8: return ClockType; case 0xFA: return StartType; case 0xFB: return ContinueType; case 0xFC: return StopType; default: switch((data[1] >> 4) & 0xF) { case 0x8: return NoteOffType; case 0x9: return NoteOnType; case 0xA: return PolyphonicAftertouchType; case 0xB: if(controller() < 120) { // standard controllers return ControlChangeType; } else if(controller() == 123) { return AllNotesOffType; } else { return ErrorType; // unsupported atm } case 0xC: return ProgramChangeType; case 0xD: return ChannelAftertouchType; case 0xE: return PitchWheelType; default: return ErrorType; } } } <</code>> The above code, added to the MIDIMessage.h file does not work as I expected and I wondered if someone might be able to shed some light on the problem. Many Thanks, James Spadavecchia
