via this Reverb listing

"This is the holy grail of early digital additive synths: a true successor to Bell Labs' Alles Machine, built by Crumar and Digital Keyboards between 1982–85. With only ~700–800 units ever made and fewer than ~100 still running today this Synergy Mk. I stands as an ultra-rare, pro-grade instrument crafted for sonic innovators like Wendy Carlos who used it on the TRON soundtrack as well as her albums Digital Moonscapes and Beauty in the Beast.

This unit is fully functional and fully responsive. It harnesses a formidable engine of 32 digital oscillators capable of additive and phase-modulation tones, delivering 8 or 16 voice polyphony. You have 24 internal presets at your disposal, with cartridge expansion support. It’s standout feature is the ability to layer up to four distinct tones simultaneously, creating lush, shimmering textures or aggressive, harmonically rich leads. Sure, editing is minimal on-board, but that means its extremely user-friendly. Dial in a tone and go."

via this Reverb listing

"Step into the golden era of analog synthesis with this pre-owned 1975 ARP Axxe, a vintage monophonic synthesizer that delivers the unmistakable sound of the '70s. Introduced as a more accessible sibling to the legendary ARP Odyssey, the Axxe brought rich, punchy analog tones to players ranging from beginners to seasoned professionals. This early Mark I unit retains its distinctive black-and-gold aesthetic, robust metal chassis, and classic wooden side panels, all hallmarks of a time when craftsmanship and innovation defined electronic instrument design.

Renowned for its straightforward layout and characterful sonic palette, the ARP Axxe excels at producing gritty basslines, searing leads, and otherworldly effects. Its single-oscillator signal path, paired with a powerful resonant low-pass filter and classic ADSR envelope, allows for bold, expressive shaping with hands-on immediacy. Whether you're integrating it into a modular setup via CV/Gate or seeking that authentic vintage analog sound for your studio, the Axxe remains a sought-after gem with historical clout and musical relevance. Though this unit shows typical signs of vintage wear consistent with its age, it remains in solid playing condition and is ready for many more years of creative exploration."
