Unfortunately, the order in which these machines need activated is random every time. Watch and listen for Emmett's cues, he will say them loudly, and in the subtitles they will be listed in all capitals. You must get every cue/command correct without messing up once. If you mess up once and Emmett comes down to tell you to listen for his cues, then press the button and quit to the XMB. Now restart up the game and load. This will put you back at the beginning of the mixing sequence so that you may try again. Alternatively, as DarkSeraphim666 so graciously pointed out, you can simply press and load from there. Emmett will come down stairs and inform you when you have hit the 25%, 50%, and 75% marks. The speed at which the cues come increases the further you are. Beware that about halfway through, Emmett's father will begin shouting similar cues. Ignore those and focus only on the ones said by Emmett. The cues and their respective machines are:


Stoke Fire:
-Fire
-Burning
-Hot
-Flame
-Bellowing

Sprinkle Bacteria Food:
-Eating
-Food
-Microorganism

-Vent

Turn Electrical Crank:

-Current

-Generated

Watch for those cues, then use the machine associated with them. They occur in a random order remember. Once you finish this sequence, Emmett will come down and talk to you.
