Default SysEx parser goes haywire

[PoneyClairDeLune]

SysEx parsing errors out. Will not terminate parsing and start anew if the current byte goes higher than 127.

My current solution:

MidiParser.customInterpreter = function (type, file, rawMtLen) {
	// THIS MAY OR MAY NOT WORK PROPERLY!
	let u8Data = [];
	if (rawMtLen != null) {
		let metaLength = file.readIntVLV();
		if (type == 127) {
			metaLength = 1;
		};
		for (let c = 0; c < metaLength; c ++) {
			let byte = file.readInt(1);
			u8Data.push(byte);
			if (byte == 247) {
				return u8Data;
			} else if (byte > 127) {
				console.debug(`Early termination: ${u8Data}`);
				file.backOne(); // Added to let the pointer go back exactly one.
				file.backOne();
				return u8Data;
				//console.debug(`Start of another SysEx! ${u8Data}`);
				//u8Data.push(byte);
			};
		};
	} else {
		file.readInt(rawMtLen);
		u8Data[0] = file.readInt(rawMtLen);
	};
	return u8Data;
};

Update on the patch:

MidiParser.customInterpreter = function (type, file, rawMtLen) {
	// THIS MAY OR MAY NOT WORK PROPERLY!
	let u8Data = [];
	let metaLength = rawMtLen;
	if (rawMtLen == false) {
		metaLength = file.readIntVLV();
	};
	if (type == 127) {
		metaLength = 1;
	};
	for (let c = 0; c < metaLength; c ++) {
		let byte = file.readInt(1);
		u8Data.push(byte);
		if (byte == 247) {
			console.info(rawMtLen);
			return u8Data;
		} else if (byte > 127) {
			console.debug(`Early termination: ${u8Data}`);
			file.backOne();
			file.backOne();
			return u8Data;
		};
	};
	return u8Data;
};
