Toontrack Drumtracker is really (just) an audio to MIDI converter. It's great if you have
a sampler to play the MIDI info as well, be this Superior Drummer or BFD etc.
Steven Slate and Drumagog incorporate the drum sounds for full replacement.
Having used both of these I would (and did) personally go for Slate Digital Trigger.
It's cheaper, does everything Drumagog does and allows you to get your samples over those
'less than perfect' drum sounds easily.

Hexadecimal binary coding anyone?
