Details
The Lambda ES-50 is fully polyphonic It has 12 main oscillators, one each for the notes of the chromatic scale. These are divided down (divide down) to create the other octaves. The ES-50 is also equipped with 3 oscillators per tone and offers the possibility of detuning them against each other. Two envelopes and a VCA are assigned to each key.
The Lambda has two sound-generating sections and two sound-shaping sections. The percussive instruments contain the sounds electric piano, piano, clav and harmonics as well as assigned sustain, decay and tremolo. The Ensemble instruments offer Brass, Organ, Chorus as well as String I and String II, also with vibrato effect. The presets can be mixed within and between the sections. The chorus phase effect, a mixture of chorus and phaser, is generated via a modulated BBD delay. (Source: amazona)
