detune #2 and #3 against #1 with the two little DETUNE knobs.
Of course these are just HF-VCOs, and they tend to interlock, so there
is a lower limit to the beat frequency, but if you keep in mind that most
other string ensembles only have one HF-VCO plus a 3-phase chorus
to simulate 3 VCOs, the Lambda is outstanding.Arguably the worlds best string/orchestral synth--even nicer than Solina
From carbon111:-The Lambda was Korg's second or third generation "polyphonic ensemble" board, released around 1979. The Lambda's sound is unique, very analog and verges on the obese at times.The Lambda sports 48 keys and is fully polyphonic as each voice is based on three high frequency VCOs feeding TOS/Divider circuitry. The thing that saves this from sounding just like any other "string machine" or paraphonic synth is the fact that each key triggers two seperate voltage-controlled envelope generators (one for each section) for a total of 96! There are 96 discrete envelopes and VCAs in this thing! The sounds are then sent through a filter then two seperate BBD analog delays that provide a rich, warm chorus. There is also a useful "tone" control which is a simple shelving LPF.
49 note keyboard (F-F), solid case with wide wood top
and end blocks. Layerable 70's strings / brass synth sounds
Built-in phase/chorus, speed controllable by up-down
joystick movement (left-right spring-loaded joystick
controls pitch bend)
Two sections - ensemble and percussion - separate and layerable.
Separate outputs, trigger out, inputs for sustain and
volume pedal (switchable to either or both sections)
3 oscillators per note, with tuning controls and associated
beat LEDs on front panel - great for real-time thickening
and detuning, couple with chorus/phase, gives a nice big sound.
