I already did art. The denominator does not come into play. 130 is about quarters. Each quarter has 2 eighths. So, in one minute you would get 260 eighths.
It works both ways too. Try this. In a blank project that starts 4/4 at 120, write down four quarter notes. 1, 2, 3, 4. Now, change the signature to 8/8. Does the speed change? No. Now change to 2/2. Does the speed change? No. So, the denominator does not matter when it comes to tempo and Cubase. What DOES change is the click pattern if you activate the click, that will click quarters for 4/4, eighths for 8/8, and halves for 2/2. But the tempo number remains the same.
