| Description | 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. |

    		| Velocity | 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. | Aftertouch | 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. |
