The relationship between velocity layer, note velocity, recorded sample level, and playback sample level

Suppose I’m making a drumset with several velocity layers.

  1. Should a sample that corresponds to a lower velocity layer be actually quieter as recorded? Or should all samples be of equal volume, and BeatBuddy will automatically decrease the level of the sample with a lower velocity layer during playback?

  2. If I have a velocity layer defined as, say, 80 to 110, will BeatBuddy decrease the level of the corresponding sample during playback for a note velocity of 100? Or will all notes belonging to a specific layer be played back at the same level?
