Description
In 1970 EML released the venerable 400/401 Sequential Synthesizer. A portable synth and sequencer combination.

The synthesizer section is a dual VCO instrument offering only saw, square, and, noise waveforms. A multimode VCF helped shape the sound with low pass, high pass, and bandpass filtering. An envelope generator is also available with attack and release only. The unit is a semi modular monophonic instrument with a patch panel.

The accompanying 400 module is a 12 tone diatonic analog sequencer with a digitally controlled quantizer aboard. Allowing for a variable number of steps-per-octave nearly unheard of for it's day. It benefited the user who liked to explore alternate tunings and microtonal tuning. To top it off the 4000 also had voltage controlled envelope generators in 16 stages.
