I'm not sure how many people know this or bother to do so, but if you make the sample end at delta counter value 0 (or close), you can get the volume of triangle and noise channels back up where they are supposed to be. This could be useful if you use really punchy/powerful kicks to get a ducking effect to the track. If the kick sample is short enough, you may not even notice the volume drop in triangle and noise channels. Although I'm not 100% sure if the DMC channel always starts samples at 0 in the delta counter. If not is there a way to make it do so?
I also added a short demo so you can actually hear the ducking in effect
