I don't think I'm using the proper terms, because I'm still having problems. The built-in custom grid snap values always assume 4/4 time signature, right? Let's say I'm in the middle of a song, and the current measure has a 4/4 time signature. If I use the built-in grid snap value 1/24, and then press Ctrl + Shift + Page Down FIVE TIMES. And then... I set a CUSTOM grid snap value of 1/24, and then I press Ctrl + Shift + Page Down FIVE TIMES. I should seek at the EXACT same speed, no? Because I'm doing that, and it's not. The custom grid snap value is 4 times slower than the built-in grid snap value.
