Add link to your page:
```HTML
<script src="SSSynthesiser.js"></script>

var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open('GET', "http://molgav.nn.ru/x/sviridovtimeforward.molgav", true);
xmlHttpRequest.onload = function () {
	var o = JSON.parse(xmlHttpRequest.response);
	sssynthesiser = new SSSynthesiser(o);
};
xmlHttpRequest.send();
```
Start play:
```javascript
sssynthesiser.startPlaySong()
```
Stop play:
```javascript
sssynthesiser.stopPlaySong();
```
Change instruments's properties:
```javascript
sssynthesiser.findSampleBySubPath("drums/000/Chaos_128/061_046-046_60_-4600.0_8-34789_32000").volume = 0.25;
```
Control play order:
```javascript
sssynthesiser.moveToNextPosition = function(){
	if((sssynthesiser.currentX == 3 && sssynthesiser.currentY == 2) || sssynthesiser.currentY < 1 || sssynthesiser.currentY >2 ){
		sssynthesiser.currentX = 0;
		sssynthesiser.currentY = 1;
		sssynthesiser.currentPosition = sssynthesiser.findPosition(sssynthesiser.currentX, sssynthesiser.currentY);
		return;
	}
	else{
		sssynthesiser.findAndMoveToNextPosition();
	}
};
```
Play a instrument:
```javascript
sssynthesiser.playKey(sssynthesiser.findSampleBySubPath(s),1000,45);
```
Play a drum:
```javascript
sssynthesiser.playSample(sssynthesiser.findSampleBySubPath(s),2000);
```
Play a chord:
```javascript
sssynthesiser.playChord(sssynthesiser.findSampleBySubPath(s),2000,[48,52,55,60,64]);
