The Synthi E is an educational form of the Synthi that had a complete teaching course built around it for use in colleges and schools. It was intended as a teaching aid into the principles of sound synthesis and electronic music. Small, housed in a brief-case and battery powered, the Synthi E was perfect for the student or teacher on the go! Simple as it may appear, it actually has some sophistiated features:
- Input Amplifier with low (Microphone) and high (line) level inputs.
- Envelope Follower providing a voltage proportional to the amplitude of the input.
- Oscillator 1 with true exponential voltage control of frequency and three simultaneous output waveforms (sine, triangle and voltage controlled pulse).
- Oscillator 2 for slow control voltages such as glissando or vibrato.
- Filter/Oscillator 3 with v.c. low, high and band pass filter or pure sine wave.
- Modulator for envelope shaping or ring modulation. Noise Generator.
- Trapezoid Generator for multiple simultaneous trapezoid waveforms. These may be used for envelope shaping (trigger mode) or for low frequency waveforms (free run mode).
- Manual-Slide tape Controllers (2) for obtaining control voltages. One slide-tape is stepped and may be used as a keyboard and the other for variable control. One provides a trigger pulse. Both may be temporarily marked or written on.
- Inverter to invert control voltages or signals.
- Monitor Amplifier and Loudspeaker with two input mixer faders.
- A 3-octave keyboard for controlling the Synthi E is available (DKE). This unit is a mechanical keyboard which plugs into the Synthi E. It provides the correct pitch voltage and trigger signal for the Trapezoid Generator. A switch on the Synthi E selects internal or external keyboard operation.

||As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key.
||Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
