1 - Archibald 3.4.2 Archibald is a virtual drummer which improvises on your patterns. As you're building your rythm in the step by step sequencer, you determine its margin of interpretation from 0 to 100%. It gives a better sound (which drummer would play two consecutive eighth notes making exactly the same shade and attack ?). License: Demo OS: Mac OS X 10.4 Size: 38.03 MB
