Waldorf, 0-Key Synthesizer (Pulse 2)

With the heart of its legendary 1990s predecessor, the Pulse 2 monophonic analog synth module gives you three analog oscillators and a true analog cascading filter, but Waldorf took it much further. The Pulse 2's filter circuits now sport Highpass and Bandpass modes that the original never had. You also get a powerful arpeggiator, an 8-slot modulation matrix, a large LCD display, and USB. Also new is analog Filter FM and Ring Modulation, as well as what Waldorf calls "paraphonic" modes that let you voice chords with up to eight notes. There are also 500 fully-editable sound programs onboard, so you'll never run out of inspiration crafting massive basses, snarling leads, and celestial pads. The Waldorf Pulse 2. You need it.
