Psychic Modulation has re-worked and re-released Cerebrum-3 (v3.5) which is now available in free and full versions (the demo version is actually fully-functional, its only limitation being single instead of multiple outputs). It's available for Windows as a VST instrument plug-in. The full version costs $29.95.

Cerebrum-3 is a hybrid groovebox-style drum machine comprised of 5 drum synth modules, over 150 built-in drum sounds and an onboard bassline synth. Each drum section has its own dual A/B sequencer for beat-matching, as well as an Auto-Mix function.

Designed with live operation in mind, Cerebrum can be used for making complex beats on the fly that can be randomized, mixed, matched and manipulated in a number of ways.
