Drumaxx emulates real drum membranes & mallets.
I couldn't get the mac version to run in Logic 8. However it did load in other programs.
One suggestion I would have is to have dimensional values on each knobs so the user could write them down then build an approximation of their drum in real life. Like a drum shell designer. Also snare springs on / off, tightness, and size would be an interesting suggestion beyond the mallet noise knob. Searching the internet I couldn't find any software that lets you hear or design acoustic drums.
Perhaps this is similar to the Jomox M.Brane 1_1?
