Behringer's 2XM clone of the Oberheim SEM. I bought it new; I hardly played it. Includes: power supply, Box, and instructions, etc. Analog, 2 SEM clones with identical features; the 2 voices can run together or separately, so each module can receive its own sequence. Each module contains 2 oscillators and 2 ADSRs, plus its own VCF filter. Low Pass, Hi Pass, and band pass, Notch filter, Semi-modular; control it with USB, MIDI, or CV.
