Numerology gives you a step sequencing environment that provides all the immediacy and experimentation that you are looking for, but removes the limitations. It does this by giving you several powerful but easy to use sequencing modules and a flexible virtual studio environment for them to live in, complete with audio plugin hosting, audio mixing and a timeline for building arrangements.
Numerology's sequencers are not primitive modules that you have to spend weeks configuring and routing with other components just to get something playable. These are full-on MIDI and CV step sequencers that on their own are more powerful than most hardware sequencers, while still offering enough flexibility to satisfy even the most die-hard Tweaker.
But it doesn't stop there. A full suite of companion modules can be mixed and matched with the sequencers to expand their capabilities. LFO's, Envelopes, CV Mixers, MIDI Generators and processors, they're all there. There is even an integrated parameter modulation feature that makes it easy to automate anything from just about anything else.
