-    <p>
-      the biggest chiptune tracker ever made!
-    </p>
-    <p>
-      it allows you to create songs using a music tracker interface for several computer/game console/arcade sound chips.
-    </p>
-    <p>
-      it also offers DefleMask compatibility, allowing you to import your songs and even export them back for interoperability.
-    </p>
-    <p>
-      rationale for intense profanity: the tracker itself is clean, but a few demo songs and instruments contain a small amount of strong language.
