-.SYNOPSIS
+    1) Loop through an array of bus objects. 
-    Rotates through specified Voicemeeter buses, unmuting one at a time.
+    2) Mute first unmuted bus
-.DESCRIPTION
+    3) If next bus in array exists, unmute it, otherwise clear unmuted variable.
-    This script connects to Voicemeeter Potato and allows the user to rotate through a set
+    4) If every bus in array is muted, unmute the first bus specified in array.
-    of buses (1, 2, 4, and 6). When the user presses Enter, the next bus in the sequence is unmuted,
+
-    while all other specified buses are muted. The user can exit the rotation by typing 'Q'.
