|
*
|
|
* @msg SEQ_SETSYNC | Message sent to set the sequence's sync mode.
|
|
*
|
|
* lp1 is a far pointer to a MIDISync structure.
|
|
*
|
|
* @msg SEQ_SETUPTOPLAY | Message sent to tell the sequence to perform all
|
|
* tasks necessary to play. This may entail creating a tempo map for
|
|
* certain types of synchronization.
|
|
*
|
|
* @msg SEQ_OPEN | Message sent to allocate memory for and initialize
|
|
* the sequence.
|
|
*
|
|
* lp1 is a far pointer to a MIDISEQOPENDESC structure.
|
|
*
|
|
* lp2 is a far pointer to an HMIDISEQ to fill in.
|
|
*
|
|
* @comm This is the only message for which hMIDISeq is ignored.
|
|
* The seqHdr struct holds the number of tracks, the
|
|
* division type, and resolution of the sequence. The
|
|
* sequencer does all memory allocation, and much of the
|
|
* initialization here.
|
|
*
|
|
* @msg SEQ_CLOSE | Message sent to deallocate all memory used by a sequence.
|
|
* Sequence Handle no longer valid after this call.
|
|
*
|
|
* @msg SEQ_TRACKDATA | Message sent to provide a buffer of track data
|
|
*
|
|
* lp1 is a far pointer to a buffer of track data in std. MIDI file
|
|
* format.
|
|
*
|
|
* lp2 is the size of the buffer.
|
|
*
|
|
*
|
|
* @msg SEQ_PLAY | Message sent to play a sequence from current position.
|
|
*
|
|
* @msg SEQ_STOP | Message sent to stop the sequence.
|
|
*
|
|
* @comm Stops the sequence, but doesn't affect position.
|
|
* A subsequent Play message will resume from the point stopped at.
|
|
*
|
|
* @msg SEQ_RESET | Message sent to reset the sequence's position to the
|
|
* beginning of the piece.
|
|
*
|
|
* @comm Stops the sequence if playing, and sets it to play from the
|
|
* beginning.
|
|
*
|
|
* @msg SEQ_SONGPTR | Message sent to explicitly change the sequence
|
|
* position.
|
|
*
|
|
* lp1 is a song position.
|
|
*
|
|
* @comm If the sequence is in ppqn format, lp1 specifies 16th notes
|
|
* from the beginning of the song; otherwise, if the sequence is in
|
|
* SMPTE format, lp1 specifies absolute SMPTE time (hr:min:sec:frame)
|
|
* format.
|
|
*
|
|
* @msg SEQ_SETTEMPO | Message sent to explicitly change the sequence tempo.
|
|
*
|
|
* lp1 is the tempo for the sequence. For ppqn based sequences,
|
|
* this will be beats per minute. For SMPTE based sequences, this
|
|
* will be frames per minute.
|
|
*
|
|
* @msg SEQ_GETINFO | Message sent to get an info structure that reflects the
|
|
* current state of the sequence.
|
|
*
|
|
* lp1 is a pointer to SeqInfo structure.
