Why do I see two plugins listed - "Drumagog" and "Drumagog (Fixed Latency)"?

Drumagog now has two plugins to choose from when inserting onto a track: "Drumagog" and "Drumagog (Fixed Latency)". The fixed latency version is designed for use in hosts which have Automatic Plugin Delay Compensation (such as Pro Tools HD and Steinberg products). If you own one of these hosts, use the new "Fixed Latency" version for better compatibility.
