I try to serialise midi calls in time but it breaks down.

Show all headers | View raw

Without doing a countIn setInterval function that is closed "well in time" before rec is loaded it works perfect.

But as soon one try to run the countIn
MAINrecordMid.js:141 Uncaught TypeError: Failed to execute 'send' on 'MIDIOutput': Overload resolution failed.

//CALLED WHEN REC PUSHED IN HTML DOCUMENT
function recINIT() {
	console.log("recInit()"+activetrack);
	mode="Record";
	document.getElementById("keystream").value = "";
	//If record mode replace remove notes within boundary
	if (document.getElementById("recordmode").value == "REPLACE") {
		console.log("REMOVING EVENTS");
		removeTrackMessages(rectrack);
	}

	savetrack=activetrack;
	//Temptrack to record is 333 and "after cleanup" move the section into the realtrack.
