Nord Lead series. Nord Lead 2X In 2003 Clavia introduced the 2X, a refresh of the Nord Lead 2. It included increased polyphony (20 voice), high-resolution 24-bit 96 kHz DACs, and vastly expanded patch memory. The PCMCIA patch storage was removed. The 2X retains the synthesis engine of its predecessor and consequently its sound characteristics. Nord Lead 2X Anniversary Edition In 2008, Clavia released a special limited edition of the Lead 2X with inverted key colors (black keys and white sharps/flats) and special logos to commemorate the 25-year history of the Clavia company. Each unit (of only 300) came with an individually numbered certificate. Nord Lead 4 In 2013 Clavia announced the Nord Lead 4 at the annual Musikmesse show in Germany. The new variant boasts an updated sound engine, new filter sections and a "True Voice Unison" mode which can support up to 4 oscillators simultaneously. Furthermore, similar to the Nord Wave, the Lead 4 has a dedicated FX section featuring reverb, delay, crush and distortion. The ability to quickly edit sounds whilst performing live is made possible as a result of the new "variation" controls in which the user can map up to 7 control parameters per program. Also similar to the Nord Wave, the Lead 4 supports MIDI I/O over USB 2.0. Nord Lead A1 At NAMM 2014, Clavia announced the Nord Lead A1. The model attempts to make the Nord Lead line accessible to a wider user base, with a new oscillator interface and numerous enhancements intended to facilitate quick and creative sound design.
