Oberheim Legacy: In 1974, Tom Oberheim imagined a small synth as an accessory to his DS-2A digital sequencer. But it was Dennis P Collins, a gifted ARP engineer, who designed the multimode filter of the Synth Expander Module (SEM). This unique filter is a 12 db filter that cannot deny its lineage with the ARP 1047 (ARP 2500) and ARP 2023 (white Odyssey MK1) filters, 12 db filters also designed by Dennis P Collins. With two very fat VCOs and a devastating sync (also close to the Odyssey VCOs), the small SEM offers a powerful sound, very present in the mix and very different from Moog and other synths with 24 db filters. So despite its simplicity and a filter that does not enter self-oscillation, we can get a lot of sounds out of it. Accessible and easy to use, the SEM is a success. In 1975, Tom paired first two, then four, into a huge keyboard case, creating the first "true" polyphonic instrument in history, the "Four Voices." In 1976, the SEM was even expanded to eight. Nicknamed the "White Elephant," its sound was as enormous as the instrument itself! But in 1978, the brilliant Prophet-5 made it obsolete, and Tom designed the OB-X, whose channel cards were also clones of the SEM. Subsequently, the OB-XA and OB-8 used Curtis chipsets and no longer had quite the same sound. In 2010, Oberheim reissued the SEM identically, but with all surface-mount components. In 2011, the SEM PRO added just a MIDI interface.

NRsynth "Solo": This is an "extended" version of the SEM, handcrafted with traditional through-hole components. Only the envelopes have been modified for a punchier result; the rest is identical to the original synth. Additionally, the Solo features a sub-oscillator, a glide, white noise, and many more modulation options than the SEM. MIDI velocity is also supported. Finally, the white metal case gives way to a luxurious, classically crafted cabinet with waxed oak sides and black tolex, similar to a Marshall amp.

A patchbook of all Séraphin Palmeri's sounds is included with the device.
