The create-midi-sequence snippet is missing from the current docs.

1. How do we extend a sequence that was added with the Create function?
2. How do we create a sequence that uses multiple time signatures?
3. What is the difference between a sequence and a track?
4. How many sequences can I have?
5. If I make a sequence that is one bar in 4/4 and I add 5 quarter notes to it, what happens?

@d-healey All of the answers depend on whether create appends the currently-loaded sequence. There's a typo in the docs, so the answer is unclear.

[d.healey]

@clevername27 Create adds a new sequence.

get the sequence time signature, modify it, set it back add your extra notes

	//	get current sequence event list
	local list = MIDIPlayer1.getEventListFromSequence(1);
	
	//	get current sequence timesignature
	local ts = MIDIPlayer1.getTimeSignatureFromSequence(1);
	Console.print(trace(ts));
	
	//	modify timesignature, here we extend it to 2 bars instead of 1
	ts.NumBars = 2;
	MIDIPlayer1.setTimeSignatureToSequence(1, ts);
	
	//	add extra notes
	local extraNotes = [];
	
	addNote(extraNotes, 1, 75, 127, 4, 1);
	addNote(extraNotes, 1, 72, 127, 5, 0.5);
	addNote(extraNotes, 1, 67, 127, 5.5, 0.3);
	addNote(extraNotes, 1, 65, 127, 6.11, 0.5);
	addNote(extraNotes, 1, 63, 127, 7, 1);
	
	//	push the "extra notes" into the current event list
	for (e in extraNotes)
		list.push(e);
	
	//	set the list back into the right sequence
	MIDIPlayer1.flushMessageListToSequence(list, 1);

2. How do we create a sequence that uses multiple time signatures?

I don't think that is possible, you have only 1 time signature object per sequence
But you could have several sequences with different time signatures and flip between them I guess

5. If I make a sequence that is one bar in 4/4 and I add 5 quarter notes to it, what happens?

The length of the sequence will be the same

Thank you for the details answers. So for this one, will the last note just not be played since it is beyond the length of the sequence?

[ulrik]

@d-healey Yes
