+ * Tests that should be performed:
+ * -------------------------------
+ * - Run without port connects (shouldn't crash)
+ * - Run without output ports connects (shouldn't crash)
+ * - Run with buffer size 0
+ * - Run with VERY LARGE buffer size (>1MB?)
+ * - Run with buffer size a prime number (and thereby not power of 2)
+ * - Run with HUGE number of midi events in one buffer (10000)
