"The Lambda ES50 is a vintage (1979 / 1980) poly-ensemble type synthesizer with slightly editable preset orchestral sounds. It is divided into two sections: The Percussion set includes preset pianos, clavis and harmonics; The Ensemble section has presets for brass, strings, organ and choruses. Filter and envelope controls affect the different instruments individually. The Lambda has 96 discrete envelopes and VCAs - two for each key - a very unusual design. There are also vibrato and chorus effects.The Percussion group and Ensemble group each have their own separate volume contols and with the MS -01 controller foot pedal (also included), these can be blended during play as required. A joystick is proveded left of the keyboard for simultaneous control of pitch bends and chorus phase speed.
The String sounds are the nicest sounds this synth can create. With three oscillators you can vary and detune them enough to get a nice layered analog string. The piano sounds on their own are limited but they do add 'attack' to the blend of sounds as required. The Lambda is cased in a lovely polished wood that gives it that authentically vintage status. I have built a flight case (included) which has kept the original woodwork in very good condition except for two small chips on the front edge.
