A rather enhanced version of the Leviathan sequencer, upgraded for Reaktor 4.1.
Archimedes supports a wider range of sequence mutations than Hobbes, more similar to that of Husserl than any of the other Metamusic ensembles. For example, pitch triggers can be restricted into ranges (so MIDI input in different octaves, for instance, can trigger different sequences); one sequence can change the volume of another sequence independent of whether it is also its trigger source; and so on. The tooltips provide lots of information.
This ensemble now has MIDI output, and with 4.1 it can thus be usd inside your Cubase or whatever sequencer you prefer to generate MIDI patterns for other synths.
The structure uses multiclient tables which greatly simplified the design and is much more robust.
