The EML 101 is a 4 VCO analog semi-modular patchable synthesizer with a multimode voltage controlled filter. 2 out of the 4 oscillators can also be used as LFO's with multiple waveforms.
EML was confident in saying they had the most stable oscillators over the competition at the time because they used OP amp circuits as opposed to transistors. it was thought OP amps had more stability and less drift. The instrument also had a unique ring modulation feature called a "variable modulator" that can move between being a ring modulator or to any percentage amplitude modulation.
The unit also has a 44 key duophonic keyboard. A nice feature was playing 2 notes at a time which was rare in these early days of synthesis design. Another welcomed feature was microtonal tuning.
Another cool feature was their Sample And Hold setting that they called "The Sampler"which as expected generated random ordered sequences of tones, or produced spontaneous changes in timbre, or control of the entire synthesizer in place of the keyboard.
And they didn't stop there until they put in 2 multi-stage envelope generators, 4 mixers, a noise generator, a microphone amplifier, and a full patch panel.
