We've been fans of the original Novation Circuit here - Nick bought one for his live setup and we often recommend it for people wanting a simple computerless music creation instrument.
The new Circuit Tracks, replaces the original Circuit and adds some new features and bakes in much of the Firmware updates that the original Circuit recieved. Indeed, we know there is also a roadmap for the new Tracks too.
