Ah, that may be it. Assuming it has different velocity layers, I tend to use 120 for kick and snare (save for fills) and 90 / 75 for the toms (strong / weak hand). For the hi-hat and cymbals I’ll use 100, though sometimes a particular cymbal will be a tad weaker so I’ll push it to 120.
Remember the strong / weak hand part. If you’re a right handed drummer, you tend to emphasize the right hand hit a bit more. So you’ll have (LRLR) 120 100 120 100 for velocities. But there is also emphasis placed on the quarter note (assuming 4/4 time) so you’ll get (LRLR) 120 90 105 90. Etc. Same goes with toms, hi-hat, and ride cymbals.
