No sound when convert from json to midi

[motniemtin]

I discovered a problem in your source, When the midi file switched to json everything was fine. But when switching from Json to Midi, the controlChange value when parse is equal to 0. The problem is that when parse json, the value does not convert to 0 ~ 127 but it is still 0 ~ 1.
Change Track.ts 252->270 to

fromJSON(json: TrackJSON): void {
		this.name = json.name;
		this.channel = json.channel;
		this.instrument = new Instrument(undefined, this);
		this.instrument.fromJSON(json.instrument);
		if (json.endOfTrackTicks !== undefined) {
			this.endOfTrackTicks = json.endOfTrackTicks;
		}
		for (const number in json.controlChanges) {
			if (json.controlChanges[number]) {
				json.controlChanges[number].forEach((cc) => {
					this.addCC({
						number: cc.number,
						ticks: cc.ticks,
						value: cc.value*127,
					});
				});
			}
		}
