You need to trigger the subtractor, so I think he means play your keyboard, not "press play". Also the cv that goes into the pitch should be turned up to full on the back, or else it will be out of tune.
The difference between this and the other stuff discussed in this topic, is that this one follows the sync of the matrix, whereas the ones with the delayed sounds will follow your own timing (good or bad).
