"This EML 101 is fully serviced by in-house technicians, fully functional and in great condition. It sounds awesome.
The ElectroComp 101 is the successor to the rare ElectroComp 100 from Electronic Music Laboratories (EML), a small synthesizer company based out of Connecticut in the USA. Like the ARP 2600, the 101 is a patchable (1/4'' patch cords) semi-modular synth with a pre-wired voice path that can be over-ridden via patching. But unlike the ARP (or MiniMoog for that matter), the 101 has as many as four oscillators (two of which can go sub-sonic, for use as LFOs). The 101 is also Duophonic so you can play up to two notes at once. Another major distinction was that unlike Moog and ARP, who used transistors that would tend to drift out of tune under various operating temperatures, EML used op amps which proved to be far more stable and reliable.
Other onboard features include a voltage controlled 12 dB/oct multi-mode filter with resonance, two envelope generators, ring/amplitude modulator, noise, and sample-and-hold (they call this the "Sampler"). In addition, the 101 makes no distinction between control voltage and audio paths allowing just about any source to be patched to any control or audio input in any order. The 101 could easily be closed, secured and carried inside its wood casing.
This synthesizer is fantastic. It's warm, punchy, powerful and has lot of bite not to mention a sound that sets it apart from its contemporaries and, for that matter, any other synth."
