+//3 - play with the multislider
+//4 - when you like a spot, click entry (become read) then a position in the 2D graph where this point should be
+//5 - do that for a few points
+//6 - click train
+//7 - the 2D graph controls the 10D
+//8 - if you like a new sound and you want to update the graph, just click entry, then where it should be in the 2D, then retrain when you are happy
