The FM Drum machine is, in my opinion, the highlight of the DN2, and probably the machine I use the most. It’s a great starting point to quickly dial in drum sounds on its own, AND a fantastic exciter for the comb filters. The ability to mix between body / transient / noise layers is great.
Using the Comb- filter, you can get a lot of woody physical modelling percussion sounds. It sort of reminds me of the SSF Entity Percussion, or Intellijel Plonk in some regards. Comb+ tends to be better for strings, pianos, flutes, etc., but I’ve also gotten some great sounding snare and tom sounds out of it. The combo of FM Drum and Comb Filters is super versatile.
DN2 provides a lot of shortcuts for creating percussion sounds easily with the FM Drum machine, but it’s also a lot more versatile than any of the Nord Drum engines and personally I prefer the way it sounds. I’ve had Nord Drum 2 and 3p and they always seem to have a dullness to their sound I can’t get past.
