If you are viewing this listing you most likely know what this analog/digital synth, true multi-sampler, and sequencer is. It is an amazing piece of equipment and has no rival. Quite simply, nothing can do what this does. It has 4 ocs, 2 filters, 6 envelopes, time linearity modulation, continuously variable waveshapes, an amazing sampler, an amazing sequencer, an 8 band fixed filter bank, the ability to record every knob movement, effects, and both analog and digital synthesizers. If you are not familiar with this synth go to You Tube and type in Spectralis 2. You will want to get one the instant you hear its ability to make creative electronica of all current genres. Also, read reviews by googling Spectralis review. They are VERY RARE. Thanks for looking and good luck! Includes Joerg Schaaf's Spectralis Sample Library vol.2 and the user manual. Works everywhere with switching voltage.
