Nord Wave 2 61 Key Synthesizer

We say:

The Nord Wave 2 61-Key Performance Synthesizer combines four independent synthesizers into one unit, offering exceptional possibilities for layering classic waveforms and samples. This can all be monitored through the OLED displays for program and oscillator sections. This, along with the instantly tweakable, hands-on effects contribute to the Wave 2 being Nord's most versatile performance synthesizer ever.

Nord say: 

The Wave 2 is packed with a range of features that will help you find your sound. Four oscillator types, multi-layer capabilities, six filter types and a huge range of effects mean that you'll never run out of creative tools. This is done using Nord's trademark quality audio, with high-quality samples taken from Nord Sample Library 3.0.
