The new C2 OS v2.00 update will give your Nord C2 the same B3 organ engine and rotary emulation as the new Nord C2D. This includes the improved B3 Key Click (with an added Key Bounce menu setting, and an extra high Key Click level available in the Sound menu), improved B3 Percussion behavior, improved B3 bass response and the new 122 Rotary model from the C2D (in both close and normal mic-positioning).
