A
polyphonic analog orchestral synthesizer with a 48-
note keyboard. Released in
1979.
The Lambda offers 9
preset sounds, and is
dibided into two
sections. The
percussion section features
pianos,
clavis and
harmonics, while the
ensemble section offers
brass,
strings,
organ and
choruses.
The sounds are generated by 3
VCOs,
modulated by a 60/120/360 degree
LFO to create
basic ensemble sounds. A single
VCF plus two
discrete VCA EGs per voice (!) affect the
instruments individually.
Vibrato and
chorus effects are also available.
For
interfacing with other equipment, the Lambda includes a
gate-out. Reportedly
third party MIDI retrofit kits are very easy to
install on the ES-50.
