Music Visualiser Troubles

It's quite difficult to describe what is the issue here so here is the code, insert any audiofile you have into the scene and drag it into the script via the inspector, add as many cubes as you like, tag them as "Cube" (make cube tag as "Cube" and duplicate), drag the camera from the scene into the script and run the scene.

 using UnityEngine;
 using System.Collections;
 
 public class SamplerScript : MonoBehaviour 
 {
     //Public Variables
     public int sampleNum;
     public int channel;

     //Private Variables
     private float[] arrVolume;
     private float[] arrFrequency;

     private float sumFrequency;
     private float avgVolume;
     private float avgFrequency;

     private float minFreq;
     public int cubeCount;
     private int count = 0;
     public GameObject[] cubes;
     private float divSamples;
     private int loopCount = 0;
 
     // Use this for initialization
     void Start () 
     {
         //Set Up Arrays
         arrVolume = new float[sampleNum];
         arrFrequency = new float[sampleNum];
         cubes = (GameObject[])GameObject.FindGameObjectsWithTag("Cube");
         cubeCount = cubes.Length;
         mainCamera.transform.position = new Vector3(cubes.Length / 2, 0, -cubes.Length / 2.5f);
         print("Cubes Positions");
         orderCubes();
     }

     {
         loopCount = 0;
         foreach (GameObject cube in cubes)
         {
             cube.transform.position = new Vector3(loopCount, 0, 0);
             loopCount++;
         }

         //Itterate through each sample

                 {
                     cubes[count].transform.localScale = new Vector3(1, arrVolume[i] * 40, 1);
