+    a note for future reference:
+
+    all stored swing values (like ones in remix.json) are the SWING RATIO - 0.5
+    for example, a swing ratio of 50% would be 0.5 - 0.5 = 0
+    and a ratio of 66.67% would be 0.6667 - 0.5 = 0.1667
+
+    you put that final value into tempoObj.SetSwing() to set it,
+    hence why the above functions use that weird formula and the below functions set it directly
+
+    in addition, you can get the swing ratio (as a percentage) from this value by
+    multiplying the value by 100, then adding 50
+
+    this is really stupid lol
+    minenice why didnt you write any of this down lmao - zeo
