We first reviewd the Cicuit when it came out, Novation's new groovebox was great fun and very promising, however, it had a few short comings. Since then, almost a year back, Novation have steadily added features and transofrmed the Circuit into something rather different.
New features include:
OS 1.4 is a free download
Emulate multiple mics, change proxmity and axis on the fly with UA Hardware
This crazy oscillator now has even more features
