AbletonLink.cs is a wrapper script for UnityAbletonLink plugin. AbletonLink class is the singleton. So you can access it by using AbletonLink.Instance.

Write some code in Unity

Write some script to use this plugin. For example,

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Example : MonoBehaviour
{
	private AbletonLink link;

	void Update ()
	{
		double beat, phase, tempo, time;
		int numPeers;
		
		// We can get the latest beat, phase and tempo as follows.
        AbletonLink.Instance.update(out beat, out phase, out tempo, out time, out numPeers);

		Debug.Log ("beat: " + beat + " phase:" + phase + " tempo:" + tempo);
	}
}

Attach the script to a GameObject (e.g. Main Camera or something).
