I have their latest version, DFH Superior. They have three big things going for them:
- Very high quality samples
- The way the hits are humanised - hit a snare drum twice and the hits don't sound the same
- They are raw sounds, just like you had recorded the drums yourself.
If you want authentic, high quality drums the only way to do better is to mic a real drummer, and even then most of us wouldn't do it as well.
The drawbacks?
- The interface is hardly user friendly (although they have just released a new version, which is probably better - I can't be bothered to load it right now)
- You have to programme them through MIDI; you can use other folks' MIDI files, once you have spent time remapping them. It's tedious.
- They are not a quick, simple solution; it takes a great deal of work.
And I agree with the tone of your comment Fusion, when I think you were saying I think that Toontrack don' thelp themselves much, or make it easily approachable. Nevertheless, they do sound great.
